Groudon Movesets & Wettbewerbs-Sets

In a metagame where Restricted Pokemon run rampant and the premier teams are sun teams, Groudon is easily a top contender. While Groudon is certainly threatening by itself, it's so good more because Drought serves as a catalyst for two of the metagame's most dangerous Pokemon, those being Charizard and Venusaur. Precipice Blades is Groudon's strongest STAB move and gives it access to Max Quake to boost its weaker Special Defense. Groudon has more consistent STAB options, but there is simply too much opportunity cost to reasonably justify them. Rock Slide gives Groudon means to hit Flying-types such as Zapdos and Yveltal, and most critically it threatens an OHKO against Dynamaxed Charizard via Max Rockfall. Swords Dance is useful for offsetting Intimidate from the likes of Landorus-T and Incineroar, and thanks to Groudon's bulk, it can oftentimes get one or even multiple boosts. Sitrus Berry improves Groudon's longevity as a bulky Swords Dance user and support Pokemon to Charizard and Venusaur. Alternatively, Groudon can run White Herb in order to offset Intimidate and make itself generally more threatening; however, Groudon oftentimes doesn't need to be more threatening because its teammates do that job. The given EV spread allows Groudon to outspeed -1 Thundurus and outspeed Tornadus while at +1, both of which are relevant given Groudon is often paired with Charizard, which can use Max Airstream, and Electroweb Regieleki. Groudon should always be paired with Venusaur and almost always with Charizard; there is simply little reason to not use Pokemon that are so powerful in the sun. Venusaur helps Groudon by thwarting Water-types such as Rotom-W, Blastoise, and Kyogre. In return, Groudon can thwart Fire-types like Incineroar and Coalossal. Charizard can assist Groudon by checking Grass-types such as Rillaboom and Venusaur, while Groudon can check Regieleki and Coalossal for Charizard. Regieleki is a great teammate for being one of the best answers to Kyogre teams, and it can also provide Groudon speed control with Electroweb. Grimmsnarl can provide dual screens to bolster Groudon's already good defensive stats, which can help it set up with Swords Dance more safely. Grimmsnarl can also mitigate Groudon's middling Speed via Scary Face or Thunder Wave. Porygon2 is a great partner for Groudon because it's a great check to Landorus-T with Ice Beam, most importantly, and also Calyrex-S with Eerie Impulse, which are both Pokemon that can greatly trouble Groudon teams. Porygon2 can also provide speed control to Groudon with Trick Room. Incineroar supports pretty much every Pokemon well and Groudon is no exception, appreciating Incineroar's ability to keep the likes of Venusaur, Rillaboom, and Calyrex-S in check if it's running Assault Vest. Umbreon is one of the best answers to Calyrex-S and also a solid answer to Calyrex-I, both of which can greatly trouble Groudon and its common teammates. Note that running Umbreon gives up the ability to reasonably justify Porygon2, which compromises the matchup against Landorus-T.

Precipice Blades, despite the accuracy concerns, is still Groudon's most effective way to deal damage. When Dynamaxed, Groudon can use Max Quake to boost its Special Defense, which is hugely effective in tandem with Assault Vest. Stone Edge is a strong option for hitting Pokemon immune to Ground like Thundurus, Charizard, and Yveltal, but Rock Tomb can be used to support Groudon's teammates by slowing down foes. Stone Edge also has the stronger Max Rockfall at 130 BP compared to Rock Tomb's 110. Fire Punch lets Groudon deal consistent Fire-type damage, as Heat Crash will fail against a Dynamaxed foe and does less damage to Zacian-C. Heat Crash, however, does more damage against most other non-Dynamaxed foes thanks to Groudon's weight stat, including getting the OHKO on Amoonguss. Shadow Claw lets Groudon OHKO Calyrex-S and do big damage to Lunala. Heavy Slam hits Grimmsnarl and provides Max Steelspike, giving it access to both defense-boosting Max Moves. Giga Impact is used for Max Strike, slowing down foes and keeping them in check for partners like Charizard, Zacian-C, and Calyrex-S. Assault Vest is massive for giving Groudon a leg up against special attackers; Kyogre, Calyrex-S, and Charizard all have a much harder time breaking through Groudon with additional Special Defense.

Precipice Blades is Groudon's best Ground-type move and deals spread damage without threatening its partner. Max Quake can help Groudon by giving it Special Defense boosts to better matchup against Calyrex-S and Kyogre. Rock Slide hits many common Pokemon immune to Ground like Charizard and Thundurus, and can deal significant damage when Groudon has boosted Attack. Rock Tomb, while significantly less threatening offensively, can be a great help for its partners like Yveltal and Lunala, allowing them to outspeed the faster Pokemon like Thundurus, Zacian-C, and Calyrex-S. Swords Dance is Groudon's best way at counteracting Intimidate from Incineroar and Landorus-T. Bulk Up is slower to boost its Attack, but the Defense boost can help against physical attackers, such as making Zacian-C's +1 Behemoth Blade a guaranteed 3HKO and instantly garnering an advantage in Groudon wars. At +1 Attack, it can OHKO 252 HP / 4 Defense Zacian-C. Sitrus Berry and Leftovers provide Groudon with slight HP recovery which goes a long way to improve its longevity, but White Herb helps cancel out Intimidate drops as well as some annoying drops from Max Moves like opposing Max Wyrmwind, Max Phantasm, and Max Darkness.

Groudon's great Attack and Defense make it a physical tank capable of taking on dangerous physical attackers like Necrozma-DM, Zygarde-10%, Zeraora, and Zamazenta-C. Groudon is a good Stealth Rock setter thanks to its ability to pressure and force out common Defoggers like Ho-Oh and Tornadus-T. Despite having lower accuracy than Earthquake, Precipice Blades is noticeably stronger, allowing Groudon to nab more KOs, such as an OHKO on Victini and Zygarde-10% at +0 and Necrozma-DM and Zamazenta-C at +2, all while avoiding damage reduction from Grassy Terrain. Stone Edge targets Flying-types like Yveltal, Rayquaza, and Ho-Oh, while Heat Crash more directly pressures Corviknight. Swords Dance helps Groudon force out defensive Pokemon that can comfortably take its hits or clear its Stealth Rock, most notably Landorus-T and Magic Guard Clefable. Alternatively, Toxic cripples Landorus-T and other switch-ins like Tangrowth. 16 Speed EVs help Groudon outpace neutral natured Magnezone without a Speed donation, as well as Victini at -1. Defensive Groudon is best used on bulky offense builds that can make use of sun. Fire-types are natural partners, thanks to Drought supercharging their attacks and their ability to cover for Groudon's Grass and Ice weaknesses. Victini is perhaps the best partner, using Groudon's sun and great Attack in combination with V-create to overwhelm even bulky Fire-resistant foes like Ho-Oh and Slowbro. Heatran is also notable thanks to its ability to take Fire-type attacks that Groudon teams tend to struggle against while also benefitting from Groudon's Speed donation and Stealth Rock to better act as a trapper. Defense receivers like Clefable, Alolan Persian, and Gastrodon act as secondary physical walls to make up for Groudon's lack of reliable recovery. The former two can provide pivoting and deal with physical threats that Groudon struggles against like Weavile, Kyurem-B, and Kartana, while Gastrodon can take on Kyurem-B and Choice Scarf Victini. Clefable and Gastrodon also absorb Scald and Knock Off that would cripple Groudon. Rotom-W, Landorus-T, and Corviknight appreciate Groudon's defensive donations to help clear away entry hazards. Ferrothorn, Tangrowth, and Buzzwole can also make use of these donations to help against special attackers.

Offensive Groudon forgoes its utility to become a fearsome wallbreaker. Thanks to its good natural bulk and defensive typing, Groudon finds ample opportunities to set up against common defensive Pokemon like Magic Guard Clefable and Tornadus-T. Precipice Blades is its preferred STAB attack to OHKO Zamazenta-C and defensive Necrozma-DM at +2. Stone Edge nails Flying-types like Ho-Oh, Rayquaza, and Tornadus-T and gives Groudon great neutral coverage. Boosted by sun, Heat Crash is the best option against Landorus-T, Skarmory, and Grass-types such as Ferrothorn and Tangrowth. Alternatively, Rock Polish patches up Groudon's mediocre Speed and turns it into a late-game cleaner. Depending on the team, Groudon can choose between several items. Leftovers helps it utilize its defensive stats, while Life Orb increases its damage output, allowing Groudon to OHKO Clefable and Slowbro with +2 Precipice Blades. Lum Berry is also viable to set up against foes that threaten to burn Groudon, such as Rotom-W and Gastrodon. Jolly is preferred on sets with Heat Crash to at least Speed tie with opposing Groudon and Zekrom, while Rock Polish variants prefer Adamant's Attack boost. Offensive Groudon fits on offense teams that appreciate its wallbreaking capabilities. Choice Scarf Victini appreciates Groudon breaking through or weakening physical walls like Giratina, Gastrodon, and Slowking and benefits from its sun and hefty Attack donation. Defensive Water-types like Rotom-W and Slowking pair well with Groudon, as they can safely pivot it onto the field, take Scald from opposing Defensive Water-types, and switch into Fire-type attacks from opposing Victini and Heatran that take advantage of Groudon's sun. In return, Groudon gifts them defensive stats and takes on Electric-types such as Tapu Koko and Dracozolt that they struggle against. Corviknight and Tornadus-T deal with Grass-types like Rillaboom and Kartana and provide Defog support. Answers to Ice-types, notably Weavile and Kyurem-B, are also necessary, making Ferrothorn and Clefable great teammates, as they also set entry hazards in Groudon's place.

Groudon is one of the most threatening Dynamax sweepers in AG. With its good Attack stat and solid movepool, Groudon can find many opportunities to force out foes such as Necrozma-DM, Tyranitar, Zekrom, and Ho-Oh and set up for a potential sweep. Swords Dance turns Groudon into a deadly wallbreaker, allowing it to 2HKO Zygarde-C and Giratina as well as and OHKO Lunala and Zygarde after minor chip damage. Stone Edge allows Groudon to hit Flying-types such as Ho-Oh and Yveltal that would otherwise be a nuisance for it. Under Dynamax, Stone Edge turns into Max Rockfall, setting sand that breaks Lunala's Shadow Shield. Aerial Ace turns into Max Airstream, allowing Groudon to outspeed almost the entire metagame after a Speed boost. Maximum Speed investment with a Jolly nature allows Groudon to outpace Calyrex-S after Max Airstream has been used, while Life Orb guarantees several key OHKOs and 2HKOes after a Swords Dance boost. Groudon's best fit is on hyper offense teams, although it can also fit well on balance and bulky offense teams. On hyper offense, teammates such as Shuckle and Excadrill are able to provide immense support for it through entry hazards such as Sticky Web and Stealth Rock, respectively, enabling it to better break through its extremely limited checks. Groudon can force out common entry hazard setters such as Necrozma-DM, Tyranitar, and Ferrothorn, which is valuable because Shuckle cannot remove opposing entry hazards and Excadrill's Rapid Spin can be blocked by Ghost-types such as Marshadow and Calyrex-S. Zacian-C in particular is a good wallbreaker that can lure in Necrozma-DM and weaken Zygarde-C, and Yveltal can pressure Ghost-types like Lunala, Calyrex-S, and Giratina for Groudon and Excadrill. Teammates like Ho-Oh and Necrozma-DM can Imposter-proof Groudon, stalling out Ditto's Dynamax turns to somewhat reliably check it. Ferrothorn can check Choice Scarf Kyogre and provide Spikes support for Groudon on bulky offense teams. Other setup sweepers such as Xerneas, Nasty Plot Calyrex-S, and Dragon Dance Necrozma-DM appreciate Groudon KOing walls such as Necrozma-DM, Tyranitar, and Ferrothorn for them. In return, they can pressure walls such as Zygarde-C and full health Lunala that Groudon struggles with. To maximize Groudon's sweeping potential, the foe's Dynamax should be wasted by powerful teammates such as Xerneas, Zacian-C, and Kyogre. Groudon should generally be used mid- or late-game once its biggest checks in Zygarde-C and Lunala have been weakened from teammates' offensive pressure.

Groudon sets itself apart from other Prankster users with its stellar offensive presence, forcing out much of the tier. Haze, thanks to Prankster, out-prioritizes boosted foes and removes stat boosts. Topsy-Turvy inverts these boosts, further limiting the opponent, but will fail against threats like Yveltal and Psychic Surge Mewtwo. Thousand Arrows is a consistent STAB option, boasting 100% accuracy and the ability to force out Ho-Oh. Alternatively, Thousand Waves, when combined with Volt Switch or Entrainment, allows Groudon to pivot around while trapping and eliminating Imposter and Poison Heal users. Parting Shot lets Groudon fast-pivot in front of dangerous threats while simultaneously cutting the damage that the switch-in takes. Groudon can use Glare to provide its team with Speed control and an occasional free turn due to a full paralysis. Precipice Blades as a second STAB option enhances Groudon's offensive presence with its additional power. Groudon requires little to no support and should be used primarily to shore up a team's weaknesses rather than as the core of a team. Offensive teams greatly appreciate Groudon imposter-proofing their setup sweepers as well as checking opposing setup while also maintaining offensive pressure. Giratina and Zygarde-C are some of the few Pokemon that can switch into Groudon reliably, so Pokemon that can threaten them like Xerneas and Kyurem-B pair excellently with Groudon.

When holding a Choice Band, Groudon is a frightening wallbreaker that can easily blast holes in defensive cores, so long as it can get onto the field against the defensive Eternatus sets and Steel-types that it forces out. While it's less reliable than Thousand Arrows, the extra power from Precipice Blades enables Groudon to OHKO Zamazenta-C if it opts for Mold Breaker, or to take down Xerneas and Regigigas after a layer of Spikes on Adaptability sets. Trick neutralizes common physical walls such as Giratina and Fur Coat Lunala, and Glacial Lance is another strong option against Giratina that also knocks out Zygarde-C. U-turn can be used to pivot out from physical walls into a specially offensive teammate such as Dialga or Pixilate Xerneas, and these Pokemon can create opportunities for Groudon by inviting in easy prey like Zamazenta-C and Solgaleo. Poison Heal Regigigas sets with Swords Dance and Wicked Blow can weaken Giratina, Zygarde-C, and Fur Coat Lunala so they can no longer switch into Groudon's attacks. Against Imposter users, a teammate with solid physical bulk and reliable recovery can handle the imposter's attacks. Strength Sap Xerneas or a defensive Giratina set can perform this role effectively.

Preventing Groudon from setting up Spikes is a nightmare, as it ignores Magic Bounce with Mold Breaker and threatens huge swathes of the tier with Thousand Arrows and Glare. Strength Sap keeps Groudon healthy throughout the game, which allows it to repeatedly switch into foes such as Zamazenta-C and defensive Ho-Oh sets. Zekrom, Magearna, and other slow wallbreakers love Groudon's efficiency at spreading Spikes and paralysis; with Spikes up and foes such as Xerneas and Palkia paralyzed, they're far more difficult to switch into or force out. While Imposter Chansey must risk being crippled by paralysis to switch in against Groudon, it's still important to ensure that Chansey cannot freely set up Spikes when it does. Poison Heal Xerneas with Rapid Spin and Strength Sap helps out with this, as it can clear away Spikes, is unaffected by Glare, and can easily heal off damage from Thousand Arrows.

With a specially defensive set, Primal Groudon notably acts as a great switch-in to Primal Kyogre and a reliable way of wasting Dynamax turns from Xerneas. Stealth Rock is a great move on Primal Groudon, since its bulk and typing give it numerous switch-in opportunities against common Pokemon such as Zacian-C, defensive Necrozma-DM, and Ho-Oh. Although uninvested, Precipice Blades is a powerful STAB move that 2HKOes Primal Kyogre and non-Dynamaxed Xerneas. Stone Edge is mainly run in order to force Ho-Oh, the best Defogger, out immediately. Overheat severely punishes Yveltal if it tries to switch into Primal Groudon, OHKOing it after little prior chip damage. It also lets Primal Groudon OHKO Necrozma-DM and Ferrothorn and force recovery from Arceus-Ground. Rest allows Primal Groudon to wall Ho-Oh, defensive Necrozma-DM, and Arceus-Water throughout the entire game by curing it from Toxic poison. It also makes up for Primal Groudon's lack of reliable recovery so it can repeatedly check Primal Kyogre even during longer matches. Toxic is a niche option to cripple offensive checks such as Mega Rayquaza, Yveltal, and Primal Kyogre if they attempt to switch in on an attack or use of Stealth Rock. Roar racks up entry hazard damage and prevents Primal Groudon from being used as setup fodder by Zygarde-C, Mega Rayquaza, Smeargle, Vivillon, and an overly confident Xerneas, but it is hard to justify over other moves. Sleep Talk alongside Rest deters Pokemon like Primal Kyogre, Xerneas, and Mega Gengar from switching in and taking advantage of Primal Groudon while it is asleep, but such a set is completely walled by Flying-types and struggles to set Stealth Rock against Ho-Oh without proper team support. 252 HP and 36 Defense EVs guarantee that Primal Groudon is never 2HKOed by Zacian-C's Close Combat when healthy. The remaining EVs with a Sassy nature are used to maximize its Special Defense without compromising its damage output. If not running Overheat, Primal Groudon should use a Careful nature. A fully physically defensive EV spread with an Impish nature can be used to make Primal Groudon much better against Zacian-C, but this job is done better by Necrozma-DM, since the latter has reliable recovery and Close Combat is still a 3HKO on physically defensive Primal Groudon. Primal Groudon fits best on balance and bulky offense teams in need of a Primal Kyogre check, Stealth Rock setter, and way of wasting Xerneas's Dynamax turns. It is also a good Zacian-C check, since it is able to switch in on all of said foe's moves except Close Combat and Assurance if entry hazards are in effect. Early-game, play aggressively with Primal Groudon since only defensive Zygarde-C and Refresh Arceus formes truly counter it. Use Stealth Rock if there's a good opportunity to, but don't hesitate to use an attack or Toxic instead if you expect your opponent to send out a powerful wallbreaker like Yveltal, Mega Rayquaza, or Primal Kyogre. Even though Primal Groudon resists most of Zacian-C's moves, Close Combat is too powerful for it to handle, so having a teammate like defensive Necrozma-DM or Zygarde-C is a good idea. Ho-Oh and Primal Groudon form a potent defensive core compressing Stealth Rock and Defog that also works well at wasting Dynamax turns from the likes of Xerneas and Yveltal. Furthermore, Primal Groudon can switch into Water- and Electric-type attacks from Pokemon like Primal Kyogre and Zacian-C, while Ho-Oh can switch into support Arceus-Ground. Having your own Primal Groudon check is important too, so take a look at team options such as Zygarde-C and Arceus-Ground, both of which also improve the matchup against Mega Rayquaza, one of the most dangerous threats to Primal Groudon. Finally, Ditto can come in after Primal Groudon has been defeated by Zacian-C, Xerneas, or Mega Rayquaza and proceed to reverse sweep. It is a recommended teammate, especially if Primal Groudon is running Rest, because Primal Groudon leaves its team dangerously vulnerable to sweepers when asleep.

Primal Groudon is one of the most fearsome offensive threats in AG thanks to its impressive offensive movepool and ability to hit foes incredibly hard both physically and specially while being accompanied by its solid natural bulk, which makes it difficult to revenge kill. Eruption provides Primal Groudon with the ability to break through physically defensive support Arceus formes, notably Arceus-Ground and Arceus-Dark, that would otherwise wall it. Fire Blast can also be used over Eruption for its consistency. This consistency allows Primal Groudon to soft check Zacian-C and Primal Kyogre without having to compromise its wallbreaking prowess. Precipice Blades gives Primal Groudon a tool to do good damage even if it's been chipped enough to reduce Eruption’s power meaningfully, as well as letting it break through specially bulky Pokemon like Chansey, which would otherwise wall it. In addition, Precipice Blades also gives Primal Groudon a way to damage Primal Kyogre, Arceus-Water, and Eternatus. Stone Edge is chosen to hit Flying types, such as Ho-Oh and Mega Rayquaza, that would otherwise switch into Primal Groudon with near impunity. Alternatively, Rock Tomb can be used, trading some power for the ability to cripple switch-ins, notably affecting Zacian-C and Mega Rayquaza that attempt to switch into a predicted Stone Edge or Precipice Blades, respectively. Swords Dance allows Primal Groudon to boost past many Pokemon that would otherwise check it, such as Giratina, Zygarde-C, and Arceus-Water, all of which would otherwise be able to whittle down Primal Groudon's health while recovering off its hits. Swords Dance further strengthens Primal Groudon's offensive presence if it's been chipped too much for Eruption to be useful. Hidden Power Ice can alternatively be used for the ability to KO Zygarde after it switches into one of Primal Groudon's other moves and OHKO Rayquaza as it switches in. Either Stealth Rock or Rest can also be used over Swords Dance. Stealth Rock enables Primal Groudon to take advantage of the many switches that it is capable of forcing, while Rest allows it to recover from chip damage and status in order to replenish Eruption's power. A Hasty nature does not lower Primal Groudon's Special Defense, giving it at least some capability to deal with Primal Kyogre and support Arceus formes while still maximizing its speed and power. Primal Groudon fits well on all manner of balanced and offensive teams thanks to its incredible breaking power, defensive utility, and natural bulk. Because it can struggle to break through defensive Pokemon like Arceus-Water, Zygarde-C, and Giratina, Primal Groudon appreciates teammates that are capable of taking advantage of them, such as Xerneas, Eternatus, and Yveltal. Similarly, Pokemon such as Mega Rayquaza, Eternatus, and Zacian-C that can pressure Primal Groudon's checks are good teammates as well. All of them hugely appreciate Primal Groudon's wallbreaking prowess, which facilitates their late-game cleaning. Gothitelle is another good teammate, as it can trap both Arceus-Water and Zygarde-C lacking Dragon Tail. If Rest is used over Swords Dance, Primal Groudon should be used on a bulkier team, preferably one with either Chansey or Diancie to provide cleric support to complement Rest. On more offensive teams, Primal Groudon's relatively slow Speed can become a hindrance, so it fits best with Sticky Web support. If it's used on offense without Sticky Web support, Primal Groudon should opt for Rock Tomb over Stone Edge in order to punish switches by ensuring that it can get another hit off against potential faster switch-ins. Those teams, in return, appreciate Primal Groudon's ability to heavily pressure most common Defoggers, including Ho-Oh and support Arceus formes. Primal Groudon should be used with caution throughout the match, ideally brought in on free turns or predicted switches in order to minimize chip damage and maximize Eruption's power. Owing to Primal Groudon's weakness to chip damage, it pairs well with reliable Defoggers on balance teams, such as Ho-Oh, Giratina, and support Arceus formes. On offense, however, pressure from Primal Groudon's teammates can prevent the foe from setting Stealth Rock at all. Most of the tier's common Stealth Rock users, including Necrozma-DM, Tyranitar, and opposing defensive Primal Groudon, can't switch into Primal Groudon itself, further reducing opportunities for foes to set Stealth Rock.

Groudon is a threatening setup sweeper in AG thanks to its solid Attack stat and decent natural physical bulk, which can allow it to set up on forced switches against the likes of Necrozma-DM, defensive Primal Groudon, Tyranitar, and Ho-Oh. Precipice Blades is chosen over Earthquake to have a chance to OHKO Arceus-Water and defensive Zygarde after a Swords Dance boost while also breaking Giratina under Dynamax. Stone Edge gives Groudon a vital coverage move, enabling it to OHKO Ho-Oh and Mild Yveltal without a boost and also hit Mega Rayquaza. Notably, after a Swords Dance boost, Stone Edge OHKOes Mild Dynamaxed Yveltal from full, and Max Rockfall OHKOes any Dynamaxed Yveltal. Aerial Ace rounds out the set, as it gives Groudon a way to boost its Speed under Dynamax, allowing it to outspeed almost the entire unboosted metagame after one Max Airstream with a Jolly nature. Life Orb is chosen for its significant damage boost, which allows Groudon to land critical OHKOs on the aforementioned threats after a Swords Dance boost. An Adamant nature ensures these OHKOs, but it is worth noting that a +1 Speed Adamant Groudon cannot outspeed a Jolly Zacian-C. To overcome this issue, a Jolly nature can be used, which allows Groudon to outspeed Xerneas, Yveltal, and Modest Kyogre and Primal Kyogre while still being fairly powerful. Groudon fits best on hyper offense teams, especially those that can provide Sticky Web support to make up for Groudon's average Speed. These teams greatly appreciate Groudon's ability to break through just about every Defogger in the tier, and on them, Groudon often forces the opponent's Dynamax without even needing to Dynamax itself. Groudon greatly appreciates Stealth Rock support, which ensures the OHKO on Arceus-Water and a near-guaranteed one on defensive Zygarde with +2 Precipice Blades, as well as on Yveltal and Primal Kyogre with Stone Edge and Precipice Blades, respectively. Groudon can also fit on balance teams, although its average Speed means that it appreciates paralysis support from Pokemon like defensive Glare Zygarde-C and Thunder Wave Necrozma-DM, both of which can generate more setup turns for Groudon. Wallbreakers that can pressure defensive Zygarde-C and Giratina are important teammates to have on both Sticky Web and balanced teams. Good examples include Swords Dance Arceus formes and Ultra Necrozma on Sticky Web teams, Zacian-C on balance, and Mega Rayquaza on both. Teammates that can outright exploit Zygarde-C and Giratina, such as Yveltal and Xerneas, are equally effective options. If Groudon is used on balance, Perish Song + Whirlpool Arceus-Dark pairs especially well, since it's capable of removing Zygarde-C. Moreover, Arceus-Dark also takes great advantage of Giratina and Lunala, which avoid the OHKO from +2 Precipice Blades and can cripple Groudon with Will-O-Wisp. Since Groudon is weak to Ditto, Zygarde-C can help to Imposter-proof it on balance, while the likes of Mega Rayquaza and Yveltal can provide a Ground immunity on Sticky Web teams. Late-game cleaners that benefit from Groudon's immense wallbreaking capabilities are wise teammates on balance as well, with Zacian-C, Dragon Dance Mega Rayquaza, and Calm Mind Arceus formes being good examples.

This set turns Primal Groudon into both a good Stealth Rock setter and a wallbreaker. Primal Groudon can easily find opportunities to set Stealth Rock up or use Swords Dance against foes it forces out such as Zacian-C and Necrozma-DM. Swords Dance turns Primal Groudon into a powerful wallbreaker that can surprise and decimate bulkier teams lacking Arceus-Ground. It is especially useful for breaking past defensive Zygarde with some prior chip damage, and it also allows Primal Groudon to beat Defoggers such as Lunala and Arceus-Water. Precipice Blades is its strongest STAB attack and achieves nearly perfect coverage with Rock Tomb or Stone Edge, which targets Flying-types such as Ho-Oh and Yveltal. The EV spread guarantees that Primal Groudon is never 2HKOed by Primal Kyogre's Ice Beam after Stealth Rock damage and that Zacian-C never 2HKOes Primal Groudon with Close Combat. The Speed investment makes it faster than positive-natured Arceus formes after one use of Rock Tomb, allowing it to set Stealth Rock versus them reliably. Crucially, it also allows Primal Groudon to outspeed defensive Zygarde and Lunala and potentially break past them. The remaining EVs go in Attack with an Adamant nature to increase its wallbreaking capability. An EV spread of 4 HP / 252 Atk / 252 Spe with a Jolly nature also works very nicely as a surprise factor, since it notably lets Primal Groudon outspeed Yveltal and support Arceus-Ground and Speed tie with Timid Primal Kyogre. Usually, it is best to set Stealth Rock up as soon as possible against offensive teams. Against balance teams that rely on defensive Zygarde-C to check Primal Groudon, weaken it first while taking care not to activate Power Construct, then use Swords Dance to break through it the next time Primal Groudon comes in. Having teammates that can handle Mega Rayquaza is important because it doesn't fear much from Primal Groudon; Zacian-C and Eternatus can check it offensively, while defensive Zygarde-C can paralyze it with Glare or phaze it with Dragon Tail as long as Mega Rayquaza doesn't carry a Dragon-type move. Zygarde-C also helps a lot against opposing Primal Groudon. Having solid counterplay to Arceus-Ground such as Ho-Oh and Ferrothorn is required, too. Since this set fits best on offensive teams that can use Primal Groudon as a Stealth Rock setter and wallbreaker that facilitates sweepers' task, sweepers such as Zacian-C, Xerneas, Yveltal, and Dragon Dance Necrozma-DM make for good partners. The former two can also help with checking opposing Yveltal, which can easily use Primal Groudon as an opportunity to switch in and Dynamax. Zacian-C, in particular, greatly appreciates Rock Tomb support, since it prevents Speed-boosting sweepers such as Dragon Dance Mega Rayquaza and Ultra Necrozma from becoming faster than Zacian-C while inflicting enough damage to put them in KO range of Behemoth Blade.

Items Light Ball: When paired with Fling, this lets Groudon paralyze foes while breaking through Focus Sash, paralyze Ground-types, and bypass Taunt. Sitrus Berry: Sitrus Berry gives Groudon a chance to turn some 2HKOs into 3HKOs, such as Zacian-C's Behemoth Blade when using a physically defensive spread. Custap Berry: Groudon often gets into the activation range for Custap Berry, letting it get one last attack in before going down. This can be paired with Endure for more reliable activation, at the cost of coverage or paralysis spreading. EV Spreads 252 HP / 196 SpD / 60 Spe with Careful: This EV spread lets Groudon avoid an OHKO from Modest Life Orb Yveltal's Max Darkness, while outspeeding up to Choice Scarf Kyogre after paralysis. 252 HP / 76 Atk / 116 Def / 4 SpD / 60 Spe with Impish: This spread allows Groudon to avoid a 2HKO from Adamant Zacian-C's Behemoth Blade with Sitrus Berry, while still outspeeding Choice Scarf Kyogre after paralysis. 252 HP / 196 Atk / 60 Spe with Adamant: A more offensive spread is a suitable option for Custap variants, and makes Groudon a better Dynamax user.

Eruption is Primal Groudon's best way to deal damage quickly, 2HKOing anything that doesn't resist Fire when at full power. Earth Power complements Eruption by hitting common Fire-resistant Pokemon like Incineroar and opposing Primal Groudon, but it's important to chip Incineroar into KO range; otherwise, its 50% Berry will be activated should it be holding one. Overheat is another extremely powerful Fire-type STAB move Primal Groudon makes perfect use of, as it can OHKO Xerneas before it boosts with Geomancy and isn't reliant on its remaining HP unlike Eruption. Roar trades the attacking option to be a one-time check to boosted Xerneas, as it can take the Moonblast and then phaze it. Protect is necessary for conserving HP and keeping Primal Groudon safe from faster attackers for a turn, including Z-Move users like Lunala and Ultra Necrozma. Hidden Power Ice has limited usefulness, but it is justifiable for hitting Mega Salamence and Mega Rayquaza. A Timid nature with 252 Speed EVs is generally preferred to be as fast as possible, ensuring you Speed tie at worst with opposing Primal Groudon, but running Modest nets a guaranteed OHKO on 4 HP Xerneas with Overheat, as well as way better rolls on bulky Primal Groudon with Earth Power. Because special attacking Primal Groudon focuses on Speed and power rather than bulk, it plays better on fast-paced teams that match its tempo. This is typically in the form of Mega Kangaskhan and Tornadus, which open games fast with Fake Out and Tailwind to get the ball rolling. Mega Salamence can also be a great partner for it, as it checks opposing Primal Groudon. Xerneas and Ultra Necrozma enjoy its ability to threaten Steel-types, though the latter prefers physical Primal Groudon more often due to it matching up better against Incineroar.

Precipice Blades is Primal Groudon's best Ground STAB move, as the potential damage output is too high to consider more accurate moves with lower payoff such as Earthquake and Stomping Tantrum. It's powerful enough to OHKO Tapu Koko at -1 Attack and specially defensively Incineroar otherwise. Fire Punch serves as a more reliable STAB option that's capable of OHKOing Grass- and Steel-types such as Amoonguss, Mega Metagross, and Kartana under Desolate Land. Swords Dance allows Primal Groudon to boost its already sky-high Attack to insane levels, letting it OHKO Xerneas with +2 Fire Punch and counteract Intimidate. Dragon Claw is a good coverage option for Mega Salamence and Mega Rayquaza, which would otherwise wall it. Substitute allows Primal Groudon to block Intimidate and Spore while also giving it more freedom to attack, as it can safely sponge a hit from Primal Kyogre or opposing Primal Groudon that it would not have been able to otherwise. 108 HP and 252 Special Defense EVs guarantee that Primal Groudon will always survive an Earth Power from opposing Modest Primal Groudon, while 148 Attack EVs let Primal Groudon always OHKO 4 HP Mega Rayquaza at -1 Defense with Dragon Claw. Bulky Primal Groudon typically plays games at a slower pace because it isn't sweeping everything in a matter of turns, so pairing it with Pokemon like Incineroar, Tapu Fini, and Amoonguss, which thrive in this playstyle, is advised. A Pokemon to help with the Primal Groudon mirror match is advised, usually in the form of Mega Salamence or Groundium Z Landorus-T + Mega Gengar, as the former can wall it outright, while the latter can trap and remove it with Tectonic Rage. Primal Groudon is a great partner for Xerneas and Ultra Necrozma, as it can remove Incineroar, Mega Metagross, and Celesteela.

Moves Stealth Rock provides immense support by chipping down opposing threats. Swords Dance is an alternative option if another teammate already has Stealth Rock, enabling Primal Groudon to break through its checks such as Sablenite Mew and Hippowdon after one setup boost. It also helps Primal Groudon in covering threats that would otherwise check a purely mixed set such as Landorus-T due to it acting as a hybrid of its previous sets. Precipice Blades acts as a primary Ground-type STAB move that hits most neutral targets incredibly hard even when unboosted. Overheat is Primal Groudon's secondary STAB option that decimates the majority of its physical checks such as Arceus-Ground, Buzzwole, and Skarmory under the harsh sunlight, making Primal Groudon incredibly difficult to properly account for defensively. Eruption is a slightly more powerful option that can be used instead, as it does not lower Primal Groudon's offensive capabilities after every use; however, it relies on it staying relatively healthy. Stone Edge is a great coverage option that lets Primal Groudon target Flying-types that would like to come in against its Ground-type STAB moves such as Zapdos, Ho-Oh, and Pinsirite Entei. Smack Down may be used instead with the added benefit of grounding the aforementioned Flying-types so that Primal Groudon can target them with its Ground-type moves the following turn. However, it inflicts much less damage overall. Hidden Power Ice is another useful coverage option that can be run in the last slot to lure in and take out common Dragon-type switch-ins such as Pinsirite Zygarde, Mega Salamence, Zygarde-C, and Rayquaza, all of which can stomach Primal Groudon's STAB moves. Toxic is a useful utility option that may be used to cripple some of Primal Groudon's most common switch-ins, which include Manectite Mew, Gliscor, and Giratina-O, deterring them for the rest of the match. Set Details EVs are fully invested in Primal Groudon's Special Attack and Speed in order to maximize its offensive capabilities. A Naughty nature is preferred, as the reduced Defense from a Lonely nature would give Primal Groudon a slightly harder time checking threats such as Entei and Kartana, and it still lets Primal Groudon hit as hard as possible both physically and specially. A Naive nature may also be used to maximize Primal Groudon's Speed, letting it outpace threats such as Adamant Altarianite Zygarde and Manectite Magearna. A Naive nature also allows it to outspeed threats such as Lucarionite Terrakion and Lunala with Sticky Webs support. However, the extra boost in power provided by a Naughty nature is usually more useful in most cases. Desolate Land provides Primal Groudon with a crucial immunity to Water-type moves and a boost to its Fire-type STAB moves, letting it deal colossal damage to most neutral targets. Red Orb is required to allow Groudon to undergo Primal Reversion, turning it into a devastating wallbreaker. Usage Tips This Primal Groudon set aims at punching holes through the opposing team by utilizing its amazing mixed offensive potential to break through the majority of defensive threats in the tier. This means that Primal Groudon should primarily be using its STAB moves throughout the beginning of the match in order to wear down opposing walls for its teammates. Stealth Rock should be used when Primal Groudon can force and incoming check to switch in, as it can leave itself in a disadvantageous position if it decides to use the utility option versus common Magic Bounce users such as Blissey and Mew alongside other defensive threats that can threaten to wear it down immensely like Gliscor and opposing Primal Groudon. If Primal Groudon is carrying Swords Dance, it can exploit the switches it forces as an opportunity to set up and potentially break through its aforementioned checks. Primal Groudon should utilize its Fire-type STAB move when luring in threats that would otherwise appreciate coming in against Precipice Blades such as Hippowdon, Aggronite Buzzwole, and Landorus-T. Primal Groudon should not utilize Overheat too liberally, as otherwise it will be forced to switch out because of the Special Attack drops. If running Eruption, Primal Groudon should prioritize conserving its health to maximize the power of its Fire-type STAB move. Toxic is a great way to punish incoming defensive threats that can take on any of Primal Groudon's attacking options; however, be mindful of potential Magic Bounce users again, as Primal Groudon does not appreciate having the status condition afflicted upon itself. Team Options Additional wallbreakers such as Cameruptite Magearna and Tapu Lele can help provide additional offensive pressure to Primal Groudon's checks like Lucarionite Zygarde, Giratina, and Latiasite Toxapex, while the aforementioned threats also appreciate Primal Groudon's ability to set up Stealth Rock in return. Checks to opposing Ground-types, which include Gliscor, Golisopod, and Ho-Oh, can be extremely useful for Primal Groudon, as they can help cover its sole weakness when factoring in the effects of the harsh sunlight. Sticky Web support from setters like Shuckle may also be useful in order to enable Primal Groudon to outpace threats such as Terrakion, Kartana, and Tapu Lele; however, it should be noted that Primal Groudon should be running a Naughty nature if used in conjunction with Sticky Web. Partners that can set up Stealth Rock may be necessary if Primal Groudon chooses to forego the option itself, as the extra entry hazard chip damage can be crucial at times to secure certain 2HKOs against targets such as Mew and Zygarde. Good setters include Terrakion, Landorus-T, and Skarmory. Alternatively, team members that can remove entry hazards such as Arceus-Ground, Zapdos, and Mew aid Primal Groudon by removing entry hazards that can wear it down over time. Partners that can combat offensive Sticky Web teams may also provide utility considering Primal Groudon's weakness to the aforementioned archetype. Good examples include Altarianite Zygarde, Pinsirite Kartana, and Yveltal. Cleric and Wish support from partners like Blissey, Magearna, Shaymin-S, and Jirachi can be used to great effect especially if Primal Groudon is running Eruption due to its lack of reliable recovery, prolonging its longevity immensely and increasing the power of its STAB move as well.

Moves Stealth Rock is a great utility move that provides both Primal Groudon and its teammates immense support by chipping down opposing threats. Precipice Blades acts as Primal Groudon's primary STAB move, allowing it to target the Fire-, Steel-, and Electric-types it's intended to check such as Raikou, Victini, and Magearna while still dealing consistent damage against most neutral targets. Overheat is a powerful secondary STAB option especially under the harsh sunlight that can break through threats that would like to come into Primal Groudon's Ground-type attacks such as Arceus-Ground and Aggronite Buzzwole. The burst damage also aids Primal Groudon in providing immediate offensive momentum to its team, as it usually forces out offensive threats due to the fear of Overheat. Lava Plume is a more reliable yet considerably weaker option that provides Primal Groudon the chance to burn its targets, letting it check physical threats slightly better. Toxic is a great utility move that can cripple opposing walls such as Gliscor, Mew, and most support Arceus formes, preventing them from switching into Primal Groudon repeatedly throughout the match. Primal Groudon can run Roar over either Overheat or Toxic to phaze certain setup boosting threats such as Manaphy, Xerneas, and Altarianite Zygarde, preventing the aforementioned threats from sweeping its team. However, it generally offers much less utility compared to its other supportive options, making it less desirable as a result. Set Details 160 EVs are invested in Defense with a Relaxed nature to ensure that Primal Groudon avoids the 2HKO from threats such as Lucarionite Terrakion and Necrozma-DM. The rest of its EVs are invested in both HP and Special Defense to turn Primal Groudon into a respectable specially defensive tank that can check certain attackers such as Magearna, Azelf, Raikou, and Manaphy more consistently, allowing it to avoid the 2HKO from their coverage moves. Primal Groudon can still choose to run maximum investment in Special Defense with a Sassy nature to better check threats such as Manaphy, Magearna, and Volcarona, but the lack in physically defensive investment means that certain physical wallbreakers like Kartana and Zeraora have a slightly easier time breaking through it. Desolate Land sets harsh sunlight, granting Primal Groudon a crucial immunity to Water-type moves, permitting it to come into threats it otherwise would be unable to such as Golisopod and Manaphy. Red Orb is required to undergo Primal Reversion, granting Groudon an additional Fire typing that lets it check Fairy- and Fire-types. Usage Tips Primal Groudon is best used as a defensive pivot that is able to come in against most specially attacking threats such as Raikou, Azelf, Magearna, and Volcarona, force them out, and proceed to set up Stealth Rock reliably. However, due to Primal Groudon's lack of reliable recovery, it is advised to preserve its HP as much as possible so it can pivot in against threats such as Entei and Magearna without being worn down. Therefore, sacrificing a teammate may be necessary at times to bring in Primal Groudon safely. Moreover, Primal Groudon should set Stealth Rock whenever it is able to force a switch, as it can otherwise be worn down rather quickly if it chooses to set it up versus threats such as Terrakion and Kartana. Overheat is best used to hit key targets that would like to switch into Precipice Blades such as Zapdos, Arceus-Ground, and Landorus-T. However, one should not mindlessly spam the move, as the drop in Special Attack often forces Primal Groudon out alongside the fear of potentially letting in Blue Orb users in for free. Toxic should be used to cripple opposing defensive walls such as Venusaurite Zapdos and Arceus-Fairy, severely hampering their longevity as they come in in an attempt to check Primal Groudon. Be mindful of common Magic Bounce users such as Mew, Mandibuzz, and Blissey, as they can reflect Stealth Rock and Toxic, which can leave Primal Groudon in an unfavorable spot. Team Options Checks to opposing Ground-types such as Manectite Mew, Skarmory, and Giratina-O can all be useful partners for Primal Groudon, as they help deal with the threats that can break through it like Lucarionite Zygarde, Arceus-Ground, Landorus-T, and Gliscor. Wallbreakers that can capitalize on Primal Groudon's ability to set up Stealth Rock such as Kartana, Tapu Lele, and Zygarde may be considered as well due to the entry hazard chip weakening down their respective checks. Entry hazard removal can be very useful for Primal Groudon, as it is often pivoted in against many attacks, and the chip damage can wear it down significantly. Good partners for this role include Mew, support Arceus formes, and Zapdos. Due to Primal Groudon's ability to check most Magearna variants, teammates that are otherwise weak to Magearna such as Darkrai, Tapu Lele, and Arceus-Fairy pair well with it. Cleric support from teammates like Blissey and Magearna is also recommended due to Primal Groudon's tendency to be statused by the threats it usually comes in against such as Arceus-Fairy and Golisopod. Blissey is especially useful for passing Wish to Primal Groudon, which can help increase its longevity immensely.

Moves Rock Polish enhances Primal Groudon's Speed to respectable levels, enabling it to outpace key threats such as Diancite Tapu Lele, Terrakion, and Darkrai after one boost. Fire Blast is an incredibly powerful STAB move when used in conjunction with the harsh sunlight, permitting Primal Groudon to heavily dent most neutral targets that it hits, including most support Arceus formes. Precipice Blades acts as Primal Groudon's secondary STAB move, hitting the specially defensive walls that otherwise stomach its primary STAB move such as Blissey and opposing defensive Primal Groudon for considerable damage. Hidden Power Ice is a great coverage option that covers the Dragon and Flying-types that can otherwise wall Primal Groudon's STAB moves such as Zygarde, Mega Salamence, and Giratina-O. Stone Edge may be used instead to hit specific targets such as Ho-Oh and Golisopod for more considerable damage; however, Hidden Power Ice generally provides more coverage. Set Details EVs are fully invested in Primal Groudon's Special Attack and Speed in order to maximize its offensive capabilities. A Naughty nature is preferred, as the reduced Defense from a Lonely nature would give Primal Groudon a slightly harder time checking threats such as Entei, and it still lets Primal Groudon hit as hard as possible both physically and specially. The Speed investment allows Primal Groudon to outspeed Necrozma-DM without any boosts and outspeed key threats such as Lucarionite Terrakion and Ultra Necrozma with Sticky Web support. Desolate Land amps up the power of Primal Groudon's Fire-type moves, letting it hit most neutral targets incredibly hard under the harsh sunlight. It also lets Primal Groudon soak up any Water-type moves used against it, enabling it to check threats it would otherwise be unable to like Primal Kyogre and Manaphy. Red Orb is equipped to allow Groudon to undergo Primal Reversion, turning it into one of the best mixed wallbreakers in the tier. Usage Tips Primal Groudon should only set up once checks such as Venusaurite Hippowdon, Blissey, Ho-Oh, Lunala, Gliscor, and Arceus-Ground have been properly weakened beforehand, as it can otherwise lose the offensive momentum it needs if the aforementioned threats are kept relatively healthy beforehand. Its STAB moves should be spammed the majority of the time due to how much damage they can do against most neutral targets, where coverage options such as Hidden Power Ice and Stone Edge should be used to hit threats such as Zygarde and Ho-Oh, respectively. Team Options Due to this set's lack of Stealth Rock, partners that can set up the entry hazard are extremely beneficial, as they can wear down Primal Groudon's checks in Ho-Oh, Golisopod, and Zapdos. Good setters include Landorus-T, Arceus-Fairy, and Terrakion. Offensive threats such as Tapu Lele, Kartana, and Darkrai appreciate Primal Groudon's ability to break through most defensive cores, where the aforementioned threats can often clean up late-game once Primal Groudon has broken down walls such as Mew and Skarmory. Partners that can cover Primal Groudon's sole weakness to Ground-type threats when factoring in the effects of Desolate Land such as Golisopod, Landorus-T, and Pinsirite Cobalion may be useful, as they provide Primal Groudon a fail-safe option in covering Pokemon such as Arceus-Ground and opposing Primal Groudon. Entry hazard removers like Zapdos and Arceus-Ground can provide utility in eliminating the entry hazard chip damage that may severely weaken Primal Groudon throughout the match and leave it prone to being revenge killed. They also relieve it from the potential Speed drop of Sticky Web, which can otherwise hamper its sweeping capabilities.

Moves Stealth Rock provides both Primal Groudon and its teammates with immense support by chipping down opposing threats. Swords Dance enables Primal Groudon to break through some of its checks that may attempt to wall it such as Hippowdon and Sablenite Blissey, meaning it can set up and keep entry hazards on the opposing side more reliably. Precipice Blades acts as Primal Groudon's primary STAB move, dealing a significant amount of damage against most targets with the slight drawback of it being inaccurate. Earthquake can be used as a more reliable option; however, the decrease in power can be noticeable at times especially when facing threats such as Buzzwole, Arceus-Ground, and Mew. Rock-type coverage complements Primal Groudon's STAB Ground-type moves perfectly, hitting the Flying-and Grass-types that would attempt to switch into Precipice Blades such as Mega Salamence and Celebi. Smack Down is useful in grounding Flying-types and Pokemon with Levitate such as Skarmory and Latiasite Toxapex, respectively, so that Primal Groudon can hit them with its Ground-type STAB move the following turn. Stone Edge is a much more powerful option that can deal more immediate damage against threats where the effects of Smack Down would not matter as much, such as Ho-Oh and Golisopod. Set Details This set calls for maximized investment in Attack EVs with an Adamant nature to fully capitalize on Primal Groudon's amazing offensive presence, allowing it to 2HKO the likes of Lucarionite Zygarde and Altarianite Landorus-T with Precipice Blades. The given Special Defense and HP investment ensures that Primal Groudon can survive a +2 Focus Blast from Xerneas as well as avoid being KOed by Altarianite Landorus-T's Earthquake and Arceus-Ground's Judgment. More Speed investment can be given to enable Primal Groudon to outpace certain threats such as Necrozma-DM, Gliscor, and opposing Primal Groudon; however, forfeiting defensive investment means that it can struggle to properly check the threats it's supposed to. Alternatively, Primal Groudon can run more Special Defense by forfeiting investment in Attack to better check threats such as Magearna and Primal Kyogre. Red Orb is required for Primal Reversion, turning Groudon into a devastating wallbreaker with Desolate Land to activate harsh sunlight and blessing it with a crucial immunity to Water-type moves that permits it to come into threats it otherwise would be unable to such as Golisopod and Manaphy. Usage Tips Stealth Rock should be set up as soon as possible, as the extra chip damage it provides can be extremely beneficial in breaking through the opposing team much more consistently. Primal Groudon can often find the opportunity to set it up due to the numerous switches it can force when facing threats such as Magearna and Raikou. However, one must be mindful of potential Magic Bounce users that can reflect Stealth Rock such as Blissey, Mew, and Buzzwole. In this case, Primal Groudon should primarily attempt to properly break through the aforementioned threats by using its attacking moves or setting up a Swords Dance so that it can threaten common Sablenite users subsequently on the switch. Smack Down can be properly used to lure in and exploit threats that can switch into Primal Groudon's Ground-type STAB moves such as Zapdos, Latiasite Toxapex, and Skarmory, as it can scare out the aforementioned threats after grounding them, potentially giving it an opportunity to setup entry hazards or boost its Attack via Swords Dance. Team Options Primal Groudon appreciates partners that can check opposing Ground-types such as Zapdos, Skarmory, and Golisopod, as the aforementioned Pokemon cover Primal Groudon's sole weakness. Special attackers such as Magearna, Lunala, Darkrai, and Tapu Lele appreciate Primal Groudon's ability to break through walls like Blissey, Sablenite Magerana, and Gyaradosite Toxapex, while the aforementioned wallbreakers can dent walls that Primal Groudon may struggle with such as Hippowdon, Buzzwole, and Giratina. Other physical wallbreakers can help apply additional offensive pressure to Primal Groudon's checks, overwhelming the opposing team. Good examples include Terrakion, Ho-Oh, Entei, and Lucarionite Zygarde. While Primal Groudon can switch into certain neutral special attacks due to the small investment in special bulk, it can still be easily worn down if repeatedly brought in against threats such as Magearna and Raikou. Therefore, teammates that can ease its burden such as Entei and Aggronite Mew may be beneficial as well. Pokemon that can use Primal Groudon's checks as setup fodder may also be handy in potentially securing a sweep late-game as well, while Primal Groudon is able to cover their own checks as a result. Good examples of this include Celebi, Giratina-O, and Altarianite Zygarde. Entry hazard removal or reflection from partners such as Arceus-Fairy, Sablenite Blissey, and Mew can aid Primal Groudon in coming in more frequently, as it can avoid entry hazard chip damage. Blissey is particularly useful, as it can provide both Wish and Heal Bell support for Primal Groudon as well, increasing its longevity immensely.

Moves V-create deals fatal damage to targets that do not resist it such as Dialga, Mega Audino, and Xerneas, letting Primal Groudon check these threats. Shore Up keeps Primal Groudon's HP high, letting it continually check threatening Pokemon such as Regigigas and Mega Diancie. It has double the PP of Morning Sun, making it preferable for longer games. Stealth Rock is also viable, as Primal Groudon forces many switches, and the move gives it something to do as Prankster Dragon-types such as Giratina and Zygarde-C switch in. Alternatively, Bolt Strike deals heavy damage to Mega Slowbro, Celesteela, Ho-Oh, and other Fire-immune Steel-types like Celesteela. When boosted by Electric Terrain, Bolt Strike is a 2HKO against Mega Slowbro. Anchor Shot traps some defensive switch-ins, such as Primordial Sea Celesteela, Mega Slowbro, and Ho-Oh, preventing them from escaping the followup move. It also threatens to trap Imposter users that are not running Shed Shell, preventing them from safely switching into or staying in against Primal Groudon. Will-O-Wisp deals useful chip damage to common switch-ins such as Giratina, Zygarde-C, and Mega Slowbro and KOes Sturdy Shedinja. Thousand Arrows may be run instead of Bolt Strike as another strong STAB move that can invalidate Ho-Oh and Celesteela as checks. Primal Groudon can set other entry hazards such as Spikes if your team already has a Stealth Rock setter, but this mandates a Magic Bounce teammate to prevent Imposters from doing the same. Set Details Intimidate can soften physical blows the first time Primal Groudon comes in, allowing it to be a better check to some physical attackers that might otherwise deal fatal damage to it, such as opposing Primal Groudon. Electric Surge powers up Bolt Strike and prevents Primal Groudon from being put to sleep. Lastly, Download is useful if Primal Groudon gets an Attack raise, but this boost is often removed or stolen by its counters via Haze or Spectral Thief. Red Orb gives Primal Groudon a far more useful defensive typing, higher physical bulk, and greater power behind its attacks. An Impish nature is preferred to bolster Primal Groudon's Defense so it can better take boosted and super effective hits, notably guaranteeing that it survives Regigigas's +1 Facade after Stealth Rock damage and giving it a good chance to avoid the 2HKO from Mega Diancie's Precipice Blades. A Careful nature allows Primal Groudon to handle Mega Diancie's Boomburst better but results in Primal Groudon being 2HKOed by Precipice Blades on the switch. Usage Tips This Primal Groudon set usually plays as a defensive pivot by forcing switches that its teammates can capitalize on. Early-game, Anchor Shot is a risk-free move to click, as the only common Pokemon that can safely avoid being trapped are Zygarde-C, Giratina, Shed Shell Imposter users, and Flash Fire Aegislash. Giratina is a fairly passive Pokemon and Aegislash cannot risk taking a possible Ground-type attack, but Primal Groudon should scout Imposter users for a possible Shed Shell, which can cause them to deplete Primal Groudon's PP if they successfully trap Primal Groudon. Most other switch-ins can easily be trapped and then removed the next turn with Bolt Strike or have Stealth Rock set up on them as they pivot out. If running Stealth Rock, it is important to scout for Magic Bounce Pokemon by using Will-O-Wisp if Primal Groudon has it or by analyzing how your opponent responds to Primal Groudon. Most teams are forced to switch the same Pokemon into Primal Groudon as it comes in, making your opponent more predictable. You can use this tendency to dictate your opponent's plays, maintain momentum, and wear their team down with entry hazard damage and double switches. Be mindful of the low PP of V-create and Bolt Strike, as after either move is used up, Primal Groudon becomes far easier to switch into for the opponent. If you need Primal Groudon to check a threatening Pokemon such as Mega Diancie, Mega Beedrill, or a Poison Heal user like Regigigas or Xerneas, play more carefully with it and ensure that its HP stays high enough to take them on. Team Options This set fits on many balance teams thanks to its ability to force predictable switches. Powerful special or mixed wallbreakers, such as Choice Specs Mega Diancie, Ash-Greninja, and Pixilate Mega Mewtwo X can threaten Primal Groudon's common checks such as Shedinja, Zygarde-C, Flash Fire Steel-types, Mega Garchomp, and Giratina, and they appreciate Primal Groudon trapping and KOing their standard defensive answers such as Soundproof Mega Slowbro and Celesteela. Primal Groudon can Imposter-proof Mega Diancie and Ash-Greninja if they do not carry a Ground-type attack, as well as Pixilate Mega Mewtwo X. Setup checks such as Prankster Zygarde-C, Prankster + Haze Registeel, and Choice Scarf Imposter users can give the team a safety net against unexpected setup Pokemon, allowing Primal Groudon to play more defensively against setup-heavy teams. RegenVest Pokemon such as Dialga and Primal Kyogre check special attackers and pivot Primal Groudon in safely with U-turn. Poison Heal users such as Xerneas, Mega Tyranitar, and Regigigas provide an additional layer of protection against status, can remove items such as Shed Shell and Leftovers with Knock Off, and spread their own status to help Primal Groudon, while Primal Groudon can check powerful wallbreakers that might force them out. If Primal Groudon is running Stealth Rock, a Magic Bounce teammate that resists V-create such as Zygarde-C or Giratina can prevent Imposters from setting up Stealth Rock against your team.

Moves Shell Smash sets Primal Groudon up to sweep the opposing team and outspeed the entire unboosted metagame. V-create deals enormous damage to targets neutral to it such as Mega Audino and Arceus, and, at +2, it can even land OHKOs on targets that resist it such as Primal Kyogre and Mega Gyarados. However, the Speed- and Defense-lowering effects leave Primal Groudon slightly more vulnerable to revenge killing from Choice Scarf and priority users. Thousand Arrows allows Primal Groudon to hit Flying-types with its STAB Ground-type move and has respectable power at +2. Alternatively, Precipice Blades has a noticeably higher damage output against bulky neutral targets such as Flash Fire Ferrothorn but cannot hit Flying-types, which may allow a daring opponent to more easily pivot around Primal Groudon with immunities. +2 Precipice Blades also is a guaranteed OHKO against both Mega Mewtwo formes, sparing Primal Groudon from having to use V-create on them. Power Trip is another option that hits Mega Slowbro, Giratina, Ho-Oh, Flash Fire Celesteela, and Flash Fire Ferrothorn hard. Fleur Cannon is the best move to complement Fire-type coverage, severely damaging physically defensive Pokemon that can take Thousand Arrows and V-create such as Giratina, Zygarde-C, and Mega Slowbro. +2 Fleur Cannon has a chance to OHKO non-Assault Vest Giratina after Stealth Rock damage. Ice Beam is viable alongside Power Trip, as it hits Dragon- and Ground-types super effectively, notably OHKOing Zygarde-C at +2 regardless of its set. However, Primal Groudon loses the ability to OHKO Giratina. Core Enforcer can allow Primal Groudon to stay in against Prankster + Haze Dragon-types such as Zygarde-C, though Primal Groudon will take severe damage from the opponent's Core Enforcer if it sets up a second time, and its ability will be suppressed, degrading V-create's power. Bonemerang is another niche option that allows Primal Groudon to break through Focus Sash and Substitute users, but it is only marginally more powerful than Thousand Arrows and has lower accuracy. Set Details It is best to use a Naughty nature so that Primal Groudon's offenses are not degraded. Most priority moves are physical, and Primal Groudon can tank a few of them if it's healthy. Primal Groudon is still able to outspeed base 140 Speed Pokemon, such as Mega Mewtwo Y, after Shell Smash followed by a Speed drop from V-create. Even with a Naughty nature, Primal Groudon is still able to survive special priority moves from full HP. Red Orb is mandatory for Primal Reversion, which increases Primal Groudon's Attack, Defense, and subpar Special Attack. Download gives Primal Groudon a boost to one of its offensive stats, which synergizes well with Shell Smash. +3 Special Attack is enough to OHKO all variants of Giratina with Fleur Cannon except Assault Vest ones, which can still be KOed after Stealth Rock damage. +3 Attack allows Primal Groudon to OHKO non-Fur Coat Giratina with Precipice Blades. Usage Tips This set operates mainly as a late-game sweeper, but against teams without reliable checks to it, it can be used as a wallbreaker or an emergency check to a physical attacker. It is a good idea to keep Primal Groudon healthy enough to take priority moves such as Fake Out + Extreme Speed from Kyurem-B. Scout for status moves such as Mega Steelix's Glare and Assault Vest users' Poison Fang so that Primal Groudon does not recklessly switch into them and get crippled. Slow pivots are great for scouting for such moves and can get Primal Groudon in safely throughout the game, and Primal Groudon's threatening presence and low list of switch-ins help to maintain momentum. Utilize entry hazard damage and make offensive double switches to wear down Primal Groudon's checks, such as Giratina and Zygarde-C. Several other sorts of checks must be dealt with as well. Prankster users can remove Primal Groudon's boosts, shut it down with Encore, or force an unfavorable trade with Destiny Bond. Focus Sash users with Spectral Thief such as Mega Mewtwo X can stop Primal Groudon's sweep as well and must be worn down before Primal Groudon can sweep. Once Primal Groudon's checks have been dealt with, pivot Primal Groudon in against something that it forces out, such as a Steel-type, for a free setup turn. Be very wary of Imposter users, because they can easily countersweep or, at best, force a two-for-one trade with your Prankster Destiny Bond user. Try not to reveal Primal Groudon's set to Imposter users before it is ready to set up, as your opponent will then be unsure of what they must preserve to check it. If you have a teammate to Imposter-proof this set, keep it alive to protect yourself from being counterswept by Imposters. Be careful of faster attackers such as priority and Choice Scarf users, which can accumulate significant chip damage on Primal Groudon after its defenses have been lowered with Shell Smash or or V-create. Do not be afraid to switch Primal Groudon out after it sets up and KOes a Pokemon to save it for later, as its bulk, especially physically, is surprisingly good and might allow it to set up again. Team Options This Primal Groudon set functions as a late-game sweeper and cleaner for both offensive and balance teams, as it can easily gain a free turn to set up. Wallbreakers are key to setting the stage for its sweep. Examples include Mega Garchomp and Choice Band Mega Mewtwo X. These Pokemon can chip Primal Groudon's standard checks such as Giratina and Zygarde-C into KO range of Fleur Cannon or Ice Beam, force trades with Prankster users, defeat Sturdy Shedinja with Moongeist Beam or Photon Geyser, and wear down Imposter users that switch in to scout their sets. Imposter-proofing this set depends entirely on the coverage. For example, Shedinja can Imposter-proof all variants and keep up pressure by using U-turn on the Imposter's forced switch. Primordial Sea Celesteela can handle variants with Precipice Blades. Hyper offensive teams may not want to lose momentum switching into an Imposter-proofer, so a Focus Sash user such as Magic Guard Mega Diancie can use Spectral Thief to steal the boosts from an Imposter that copies Primal Groudon and continue sweeping with them. Offensive entry hazard setters like Stealth Rock Mega Diancie, Mold Breaker Spikes Mega Gengar, Spikes Kartana, and Spikes Xerneas can help weaken walls and break Focus Sashes with their hazards. Kartana and Mold Breaker Gengar with Pursuit can threaten Shedinja, one of the most reliable checks to this set. Flash Fire Steel-types like Registeel can switch into -ate users and threaten to trap Imposters that switch into them, both of which are otherwise threatening to Primal Groudon. Another setup sweeper such as Shell Smash Mega Tyranitar, Shell Smash Mega Gengar, or Belly Drum Necrozma-DM can finish sweeping where Primal Groudon leaves off if it is somehow KOed. Since many teams carry just a single Prankster user, trading for it can allow the other sweeper to sweep unhindered. Mega Tyranitar and Necrozma-DM can also weaken walls like Giratina and Zygarde-C early-game so Primal Groudon can KO them later. Bulky entry hazard control Pokemon such as Defog Giratina and Pixilate Rapid Spin Mega Diancie are useful as partners to allow Primal Groudon to survive priority moves. They can also pivot Primal Groudon in with a slow U-turn and absorb status moves aimed at your offensive Pokemon. Giratina can also opt to run Z-Parting Shot to give Primal Groudon a second chance at sweeping. A way to offensively check Mega Mewtwo Y and Mega Gengar is useful, as they heavily damage and outspeed Primal Groudon before it sets up. Choice Scarf Adaptability Mega Gengar and Tough Claws Mega Beedrill check these threats and can use U-turn on predicted switches. Choice Band Adaptability Mega Tyranitar can Pursuit trap Giratina, Mega Gengar, and Mega Mewtwo Y to help Primal Groudon.

Moves Stealth Rock allows Primal Groudon to support itself and its teammates by applying chip damage to any foe that switches in. Stealth Rock is especially easy to set up when combined with Primal Groudon's ability to force switches against almost any Pokemon. Precipice Blades is Primal Groudon's primary STAB move and lets it maintain a great offensive presence, 2HKOing Xerneas and Arceus. Earthquake can be used as a more accurate alternative to Precipice Blades at the cost of power; however, the drop in power is often very noticeable, notably not being able to 2HKO Xerneas and Arceus. Lava Plume is Primal Groudon's other STAB move and has great power under Desolate Land, and when used in tandem with a 30% burn chance, it lets Primal Groudon cripple a plethora of physical attackers by burning them as well as weaken down walls. Stone Edge can be used over Lava Plume to hit Ho-Oh, mostly because non-Rock-type coverage variants are forced out by Ho-Oh. However, just keep in mind this is only recommended if you are running this set on a Ho-Oh-weak team. Roar is used to phaze setup sweepers like Xerneas, Mega Rayquaza, and Arceus, and it helps rack up residual damage with Stealth Rock. Thunder Wave can be used over Roar to cripple fast threats, which help Primal Groudon and its teammates deal with threatening wallbreakers. Dragon Tail can be used over Roar as well to phaze Ground-immune Dragon-types like Mega Rayquaza and Giratina-O and can specifically hit Mega Rayquaza for a lot of damage while phazing it. However, one disadvantage of running Dragon Tail over Roar is the inability to phaze Xerneas, which is one of AG's most prevalent setup sweepers, and even if Primal Groudon is running Thunder Wave, it can at least lower Xerneas's Speed. Set Details The given EVs let Primal Groudon survive a Focus Blast from a +2 Xerneas, even after taking chip damage from Stealth Rock and one layer of Spikes. If you're running Stone Edge on Primal Groudon, use an Impish nature instead. In addition to that, the EVs allow Primal Groudon to avoid the 2HKO from Primal Kyogre's Ice Beam, Arceus-Rock's Judgment, and Giratina-O's Shadow Force. A Relaxed nature lets Primal Groudon survive an Earthquake from +2 Arceus and a Precipice Blades from opposing support Primal Groudon. A Careful nature with an EV spread of 248 HP / 8 Def / 252 SpD could be used instead to let Primal Groudon face Xerneas and Primal Kyogre more easily but makes it harder for Primal Groudon to take physical attacks. Usage Tips Use Primal Groudon to support its teammates by setting up Stealth Rock and crippling foes with Thunder Wave; this is the main focus of the set. Don't rely solely on Primal Groudon to set up Stealth Rock and paralyze foes, as its vulnerability to all forms of entry hazards and ability to get pressured by Arceus make it difficult to set up Stealth Rock repeatedly. Try to spam Lava Plume because of its incredible chance of burning foes. Be wary of using Primal Groudon's Ground-type STAB move if the opponent still has a Ground-immune Pokemon on their team, as they can switch it in on Primal Groudon and attempt to capitalize off of it. Set up Stealth Rock early-game for as much residual damage on the opponent's team throughout the match. Use Primal Groudon as a phazer to setup sweepers like Mega Rayquaza, Arceus, and Xerneas. Try to avoid a situation where Primal Kyogre can switch in on Primal Groudon to allow the harsh sun to stay up and to avoid Primal Groudon getting forced out, giving Primal Kyogre a free KO; the same applies for Mega Rayquaza coming in on Primal Groudon and making it setup bait. Team Options Primal Groudon doesn't like facing Ground-immune Dragon-types like Mega Rayquaza and Giratina-O, with the latter being able to remove Primal Groudon's Stealth Rock with Defog; Fairy-types like Xerneas, Mega Diancie, and Arceus-Fairy can be used to take care of them, and they appreciate Primal Groudon's ability to take care of the Steel-types that threaten them. Klefki can be a decent teammate because it can set up Spikes to complete a Stealth Rock + Spikes entry hazard setting core to further help cripple the foes that Primal Groudon cripples with its moves and Stealth Rock, and it additionally can take care of most of Primal Groudon's checks with Swagger + Foul Play. Arceus-Ground is also very threatening because a +1 Judgment OHKOes Primal Groudon and a +2 Earthquake 2HKOes it; Skarmory, Lugia, and Mega Rayquaza can check it. Aromatherapy and Heal Bell support from Xerneas, Blissey, Mega Diancie, and Chansey is useful to help Primal Groudon get rid of status ailments. Ho-Oh checks like Mega Diancie, Arceus-Rock, and Arceus-Water are good because Ho-Oh threatens Primal Groudon with Earthquake and it can't do anything in return. Entry hazard removers like Giratina-O and Arceus-Fairy get rid of the entry hazards that severely weaken Primal Groudon. Pokemon that can take down support Arceus formes, such as Ho-Oh, are good, considering that a lot of support Arceus formes are weak to Ho-Oh's STAB and coverage moves. Pokemon that benefit from Stealth Rock support like Xerneas, Mega Rayquaza, and Arceus are good teammates because it helps them turn would-be 2HKOs into OHKOs.

Moves Earthquake is Groudon's main STAB move and allows it to dent most neutral targets, even without Attack investment, and is much more reliable than Precipice Blades on a support set. Stealth Rock gives Groudon the ability to indirectly weaken foes for it or its teammates to finish off. Thunder Wave lets Groudon cripple fast wallbreakers like Darkrai and Ho-Oh on the switch. Rock Tomb can be used over Thunder Wave to deal decent damage to Ho-Oh and still act as a form of speed control. Dragon Tail is Groudon's main phazing move because it can damage Mega Rayquaza and isn't stopped by taunt. Roar is an alternative phazing move to Dragon Tail that hits behind Substitute, evades Protect, and hits Fairy-types. Set Details 248 HP and Defense EVs let Groudon act as a bulky tank that can survive powerful physical attacks from Mega Rayquaza, Arceus, and Primal Groudon. 12 Speed EVs let Groudon outspeed Mega Diancie before or on the turn that it Mega Evolves. Lum Berry lets Groudon check status spreaders like Klefki and Darkrai temporarily. Usage Tips Utilize defensive Groudon as a lead to efficiently set up Stealth Rock and cripple any non-Ground-type foes with Thunder Wave. Use this set to capitalize on Swagger + Foul Play Klefki and OHKO it in return or to check sleep inducers like Darkrai and surprise them with an attack. Don't try to switch Groudon in on powerful special attackers like Xerneas due to its lack of special bulk that leaves it 2HKOed or OHKOed often. Be wary of Flying-types like Mega Rayquaza and Lugia because they can often take advantage of Groudon's lack of coverage. Spam Thunder Wave when the Ground-types on the opponent's team are gone to support teammates by crippling fast foes. Team Options Regular Groudon has trouble dealing with Water-types due to the lack of Desolate Land, so teammates like Mega Rayquaza are almost mandatory. Special walls like Clefable are good teammates because they can cover Groudon's low Special Defense and provide Wish support to give Groudon a form of recovery. Pokemon that appreciate entry hazard support to get easier KOs like Mega Rayquaza and Arceus are good teammates. Fairy-type checks like Mega Gengar, Ho-Oh, and Arceus-Poison are great for taking care of Xerneas. Options for dealing with Primal Kyogre such as Primal Groudon are recommended, as this set struggles immensely with Primal Kyogre, contrary to the other listed sets.

Moves Swords Dance gives Primal Groudon a way to boost its Attack to monstrous levels, letting it break through many bulky walls like Lugia. Thunder Wave is a great utility move that allows Primal Groudon to cripple and set up on a plethora of faster foes like Xerneas, Lugia, and Arceus-Water. Precipice Blades is Primal Groudon's main STAB move because it gives it the ability to OHKO many neutrally effected foes after one Swords Dance. Rock Slide lets Primal Groudon hit Ground-immune foes like Lugia, Ho-Oh, and Yveltal; paraflinch foes when used in tandem with Thunder Wave; and it is more accurate than Stone Edge at the cost of less power. Fire Punch can be used as a secondary STAB move, but the lack of a way to reliably hit Flying-types is quite noticeable when Primal Groudon uses dual STAB over Precipice Blades + Rock Slide. Set Details Maximum HP EVs and 48 Special Defense EVs allow Primal Groudon to survive a Focus Blast from a +2 Xerneas after Stealth Rock Damage. 12 Speed EVs allow Primal Groudon to outspeed maximum Speed Diancie before it Mega Evolves. 196 Attack EVs and an Adamant nature let Primal Groudon maximize its power while maintaining enough bulk to survive moves from threatening foes. Usage Tips Use Primal Groudon early-game to paralyze as many foes as possible to make it easier to keep Primal Groudon's Swords Dance boosts for longer periods of time later on in the match and to break through walls for teammates to finish off later. Try to set up on more passive Fairy- and Steel-types like Clefable and Ferrothorn to take minimal damage while completing the set up. Setting up will likely force the passive foes out, so try to paralyze the switch-in. Don't spam Thunder Wave too often until all opposing Ground-types are eliminated, as the lack of momentum can be detrimental later on in the match. Try to avoid setting up on Toxic users like Arceus-Water if possible; however, this may be required to remove Arceus-Water from the match. Primal Groudon should be played offensively so Pokemon like Mega Rayquaza can't freely pivot into it and ruin its sweep. Team Options Stealth Rock setters like Dialga and Deoxys-S are good teammates for weakening foes to give Primal Groudon more KOs against bulkier Pokemon like Arceus-Water and Lugia. Other setup sweepers like Geomancy Xerneas, Swords Dance Mega Rayquaza, and Extreme Killer Arceus can potentially sweep after Primal Groudon cripples, weakens, or KOes their checks. Primal Groudon gets checked by Dragon-types and Ho-Oh easily if it runs Fire Punch, so teammates like Klefki, Mega Diancie, and Arceus-Rock are great teammates to deal with them. Healing Wish users like Jirachi and Latias are good to fully heal Primal Groudon to let it have a chance at sweeping again. Pokemon that appreciate support Arceus formes being gone like Mega Rayquaza and Extreme Killer Arceus are good teammates for this set as well. Mega Gengar is a good teammate for removing Skarmory for non-Fire Punch variants.

Moves Rock Polish helps Primal Groudon outspeed the entire neutral metagame after one boost, which makes it a deadly late-game sweeper. Precipice Blades is Primal Groudon's main STAB move and allows it to hit opposing Primal Groudon, Mega Gengar, and Arceus-Poison super effectively and deal a lot of damage to threatening foes like Arceus. Dragon Claw can be used to let Primal Groudon 2HKO the Dragon-types that normally wall it such as Giratina-O and Mega Rayquaza. Swords Dance can be used to give Primal Groudon a double dance set to let it perform as an insanely fast and strong attacker, allowing it to deal with bulkier threats like Lugia and Arceus-Water more reliably. Stone Edge lets Primal Groudon hit Flying-types like Ho-Oh and Yveltal super effectively and is optimal with Swords Dance because it can easily KO the aforementioned Lugia. Fire Punch can be used over Stone Edge to let Primal Groudon hit Steel-types like Skarmory and Ferrothorn super effectively, provides great neutral coverage in general, and is more reliable than Precipice Blades in the sun; however, it gives Primal Groudon the burden of not being able to hit Flying-types as reliably. Set Details Maximum Attack EVs and an Adamant nature grant Primal Groudon an outrageous offensive presence. 56 Speed EVs guarantee that Primal Groudon outspeeds Choice Scarf base 90 Speed Pokemon like Dialga, Kyogre, and Zekrom after a Rock Polish boost. 104 HP EVs and 96 Special Defense EVs let Primal Groudon survive a +2 Focus Blast from Xerneas. 124 Speed EVs can be used instead to let Primal Groudon outspeed faster Choice Scarf users like Jirachi and Genesect, but it sacrifices either Primal Groudon's ability to check Geomancy Xerneas or a substantial amount of damage. Usage Tips Use Primal Groudon to force out Pokemon like Xerneas and set up Rock Polish (and Swords Dance if you're running it) on said switches. Try to get rid of or weaken opposing Mega Rayquaza and Giratina-O before sending Primal Groudon in to sweep. Swords Dance can be a good option for pressuring support Defoggers like Arceus-Water but is less reliable against Mega Rayquaza. Non-Swords Dance variants need support Arceus formes and other physically bulky teammates gone to successfully sweep. Keep Primal Groudon healthy if it's needed for checking Fairy-types. Team Options Primal Groudon pairs well with offensive Pokemon like Mega Gengar, Yveltal, another Primal Groudon, and Arceus-Water to take care of Lugia, defensive Primal Kyogre, and Ground Arceus. Mega Gengar is an especially useful teammate for variants of this set that lack Fire Punch to give your team a way of trapping and KOing support Arceus formes and Skarmory. Darkrai is a good teammate because it can outspeed and put all of Primal Groudon's checks to sleep to help it set up later in the match. Powerful wallbreakers like Mega Rayquaza and Ho-Oh can weaken walls like Lugia to help Primal Groudon wear down the opposing team easily. Stealth Rock support from Pokemon like Arceus-Fairy and Deoxys-S is important to chip at the health of Flying-type foes and break Focus Sashes on common users like Smeargle, as the former can reliably check Mega Rayquaza and the latter can easily fit onto most offensive archetypes.

Moves Stealth Rock allows Primal Groudon to support itself and its teammates by turning more 2HKOs into OHKOs due to chip damage, and it is easy to set up thanks to Primal Groudon's ability to force foes out with its offensive pressure. Precipice Blades is Primal Groudon's main STAB move, as it lets it 2HKO most of the AG metagame. Dragon Tail lets Primal Groudon phaze most setup sweepers; it is particularly useful against Mega Rayquaza due to its Dragon weakness and decent power. However, it leaves Primal Groudon without a way to phaze Geomancy Xerneas due to its immunity to Dragon-type moves. Fire Punch can be used over Dragon Tail to give Primal Groudon a strong, sun-boosted secondary STAB move, letting it easily damage a vast majority of the metagame neutrally, as well as being able to OHKO Skarmory, Ferrothorn, and Bronzong. Stone Edge lets Primal Groudon hit threatening Flying-types like Yveltal, Lugia, and Ho-Oh super effectively. Rock Tomb can be used over Stone Edge to give Primal Groudon a more accurate Rock-type move, but the power drop is quite noticeable; however, it still lets Primal Groudon OHKO Ho-Oh and has the benefit of lowering the foe's Speed. Set Details 76 Speed EVs let Primal Groudon outspeed every Pokemon up to uninvested Xerneas and Yveltal. 152 HP EVs and 44 Special Defense EVs let Primal Groudon survive a +2 Focus Blast from Geomancy Xerneas after Stealth Rock and an Earthquake from +1 Mega Rayquaza. 236 Attack EVs and an Adamant nature let Primal Groudon 3HKO physically defensive Xerneas and 2HKO opposing Primal Groudon. Usage Tips Play Primal Groudon with minimal risk if it needs to perform both as a Geomancy Xerneas check and as a Stealth Rock setter reliably. Try to set up Stealth Rock early-game to have as much of an effect throughout the match as possible, or when Primal Groudon is forcing a switch. Use Dragon Tail when you predict that the opponent is trying to bring in an entry hazard clearer or a foe is trying to set up. If you're running Fire Punch on Primal Groudon instead, it's safe to use the move when you aren't sure what Pokemon is going to be brought in because of the decent damage it deals after the sun and STAB boosts. If you can predict that a faster foe is switching in, try to use Rock Tomb because it can cause normally threatening Pokemon to switch back out or get KOed. Team Options Offensive Ground-immune Pokemon like Mega Rayquaza and Giratina-O are good teammates for switching in on opposing Ground-types like Primal Groudon. Ho-Oh helps with covering some of Primal Groudon's weaknesses to special attacks and Ground-type moves. Fairy-types like Xerneas and Mega Diancie are helpful for taking care of the Dragon-types that threaten Primal Groudon, like Arceus-Dragon and Mega Rayquaza. Ghost- and Dark-types like Mega Gengar, Darkrai, and Yveltal are useful for threatening stall and balance teams, which Primal Groudon otherwise struggles with. All of the aforementioned teammates appreciate Stealth Rock support from Primal Groudon in return. A more reliable Xerneas check is recommended due to Primal Groudon being unable to do so after being whittled down by other attacks.

Moves V-create is an incredibly powerful STAB move but comes at the cost of a Defense, Special Defense, and Speed drop; however, the OHKO potential is usually worth it. Sacred Fire is a good alternative option because it does not lower Primal Groudon's stats and can burn the foe; this residual damage is very useful against Giratina and Mega Slowbro, whose Poison Heal sets are particularly crippled if their Toxic Orb has not yet been activated. Thousand Arrows has neutral coverage on the whole metagame, and it is a more spammable move than V-create. Precipice Blades is an alternative option for more damage, and it also can be used to better deal with Imposter users because one's own Flying-types do not have to worry about the Smack Down effect that is a component of Thousand Arrows. U-turn can be used to gain momentum and slowly wear down Primal Groudon's counters. Synthesis is a recovery move that benefits greatly from Desolate Land, enabling Groudon to heal 2/3 of its HP, at the cost of having only 8 PP. Stealth Rock and other support moves can be run effectively in Primal Groudon's last moveslot. Set Details Holding Red Orb is currently the only way to access Primal Groudon due to Primal Groudon's ban. 252 Attack EVs and a boosting nature make Primal Groudon hit as hard and possible, and maximum HP investment makes Primal Groudon as bulky as possible, while 8 Speed EVs allow it to outspeed Pokemon of the same base Speed with 0 or 4 Speed EVs. Download can boost Groudon's Attack once before Red Orb triggers; however, Primal Groudon must be switched into a Pokemon whose Special Defense is higher than its Defense, or else Download will provide a useless Special Attack boost. Intimidate is an alternative that can be used to force out fast physical attackers like Mega Mewtwo X. Primal Groudon's ability after Primal Reversion is Desolate Land, which provides a boost to Fire-type moves and a Water immunity. Usage Tips V-create should be used carefully because it has few PP and Groudon is often forced to switch after using it as a result of the stat drops. Thousand Arrows is Primal Groudon's primary means of attacking, and zero relevant Pokemon resist it thanks to its inherent Smack Down effect. U-turn is highly useful, as momentum and scouting are extremely important elements of Balanced Hackmons, and U-turn provides both. Burns from Sacred Fire help Primal Groudon wear down its checks and counters, like Mega Slowbro, faster. Stealth Rock is ideally used on the switch, but be careful of Magic Bounce from random defensive Pokemon. Primal Groudon generally can safely switch into passive walls such as Registeel and Regirock. If possible, try to scout the foe's abilities first, as Levitate and Flash Fire, for instance, can be devastating to Primal Groudon under certain circumstances. Team Options Mega Rayquaza is an excellent partner for Primal Groudon, as they can beat each other's counters. Mega Rayquaza can eliminate Giratina and Mega Slowbro, while Primal Groudon can significantly damage Steel-types and Fur Coat Chansey, both of which inconvenience Mega Rayquaza. Mega Gengar beats both of Primal Groudon's main counters, Mega Slowbro and Giratina; however, it is not a great switch-in due to its low bulk. It is highly recommended you run a counter to Primal Groudon on your team, such as Mega Slowbro or Giratina, so that Imposter users cannot exploit your set.

Moves Thousand Arrows is the best STAB option and pressures frail Pokemon. Thousand Waves is an alternative STAB option that can trap the foe, but it cannot hit Flying-type Pokemon. U-turn gains momentum, and it can slowly wear down Groudon's switch-ins. Reliable recovery is essential to all walls and other defensive Pokemon in Balanced Hackmons, so make sure you run Recover or one of its clones. Stealth Rock and other team support moves can be run effectively in Groudon's last moveslot. Leech Seed can siphon HP from the foe (a function that is particularly useful against Imposter Chansey, which has a high HP stat) and KO Sturdy Shedinja. Set Details The given EV spread makes Groudon as physically bulky as possible in order to minimize damage from moves such as Mega Mewtwo X's V-create. Safety Goggles protects Groudon from Spore and other powder moves and, less importantly, Hail. Toxic Orb is used to trigger Poison Heal, which gives Groudon additional recovery and turns Groudon into a means of blocking status. Usage Tips Groudon is an excellent counter to Tyranitar, Regigigas, and Mega Mewtwo X. These Pokemon frequently trouble Registeel + Giratina cores, making Groudon a good supplemental option. While unlikely, it is possible for fast special attackers like Mega Mewtwo Y to carry Water- or Ice-type coverage, which may be able to beat Groudon, so scouting is recommended if possible. Poison Heal is preferred for countering Tyranitar and Regigigas because these sweepers often carry Knock Off and status-inflicting moves such as Sacred Fire and Spore, neither of which matters much provided that Toxic Orb has already been activated, so it is important to get Poison Heal Groudon a safe switch so that it can be badly poisoned. Team Options Giratina can switch into highly threatening Water- and Grass-type attacks for Groudon. Gengar can check Mega Slowbro and Giratina. Chansey can deal with several of the strong specially attacking threats that can threaten defensive Groudon sets. Chansey's Imposter set is also very helpful for scouting for coverage moves that might threaten Groudon, such as the aforementioned uncommon Water- and Ice-type moves from Mega Mewtwo Y. Registeel is a good counter to Pokemon with -ate abilities, which can easily threaten Groudon with Boomburst.
