Mega Abomasnow Movesets & Competitive Sets

Refrigerate Mega Abomasnow is an excellent revenge killer that differentiates itself from other -ate Speed users with its resistance to Thousand Arrows, immunity to Spore, and low Speed stat that allows it to underspeed many of the format's slow pivots. Fake Out and Extreme Speed form a potent combination that allows Mega Abomasnow to threaten chip against sweepers lacking King's Shield and revenge weakened foes with its strong priority STAB attacks. Fake Out on its own is also able to chip opposing sweepers lacking King's Shield, letting Mega Abomasnow hard switch into unboosted sweepers on a prediction and either chip them or force them out. Boomburst is an incredibly powerful STAB move that with an Icicle Plate OHKOes opposing Giratina and allows Mega Abomasnow to force non-Wonder Guard users out the majority of the time if healthy. Stealth Rock allows Mega Abomasnow to support its team through entry hazard setting, capitalizing on Mega Abomasnow's ability to force out offensive threats; Parting Shot and Gastro Acid are good alternative options, as the former helps to retain momentum against even slow pivot Wonder Guard users like Mega Audino and Primal Kyogre, while the latter forces most opposing Wonder Guard users to switch due to the threat of Boomburst and Extreme Speed. Since Boomburst already OHKOes Giratina without any investment, Abomasnow can throw its EVs into HP and Attack. A Brave nature and 0 Speed IVs minimizes Mega Abomasnow's Speed, giving it the ability to underspeed slow pivots like Wonder Guard Mega Audino and Chansey. Mega Abomasnow works best on teams that appreciate its ability to revenge kill non-Wonder Guard sweepers, such as offense, bulky offense, balance, and dual Mega Mewtwo X teams. In particular, it works well with the ubiquitous Shell Smash Primal Groudon + Prankster Giratina + Wonder Guard Xerneas core, as even Prankster Giratina proves to be insufficient counterplay to opposing Mold Breaker Primal Groudon on its own. Offensive pressure from Primal Groudon helps retain momentum against teams that rely on Wonder Guard Xerneas to come in on Mega Abomasnow, especially if Mega Abomasnow runs Parting Shot; Prankster Giratina, especially variants running Will-O-Wisp, can switch in on healthy Huge Power users using a Fighting-, Fire-, Poison-, or Steel-type attack and force them out with either Encore or the threat of a burn. Wonder Guard Xerneas can pass Substitutes to Mega Abomasnow, which allows Mega Abomasnow to set Stealth Rock or threaten opposing switch-ins with Gastro Acid. Mold Breaker users, in particular slower ones like Mega Tyranitar, Choice item Mega Rayquaza, and Mega Latios, also appreciate Mega Abomasnow's ability to revenge kill faster threats. On faster offensive teams, Imposter Chansey is a good partner, as Mega Abomasnow struggles to deal with King's Shield sweepers; in return, Mega Abomasnow can threaten Mega Gengar and Mold Breaker Mega Diancie, two Pokemon Imposter Chansey can't prevent from setting up easily. Offensive Shadow Tag users, in particular Mega Mewtwo X, Mega Mewtwo Y, and Mega Latios, are good partners for Parting Shot Mega Abomasnow due to being able to remove Wonder Guard users not running Shed Shell, such as Xerneas and Safety Goggles Primal Kyogre. Mega Abomasnow can work well on dual Mega Mewtwo X teams due to being a fairly reliable lone revenge killer, though it faces stiff competition from other -ate users such as Kyurem-B and Mega Rayquaza. Lastly, defensive Wonder Guard users are extremely valuable for Mega Abomasnow, as they can provide Defog, Aromatherapy, and Wish support, helping for removing entry hazards, protecting against Dark Void Mold Breaker sweepers, and providing for Mega Abomasnow's longevity respectively, while also disrupting Substitute + Baton Pass Wonder Guard users coming in and trying to set up with Whirlwind.
