Moves
Drain Punch is Timburr's primary STAB move, as it provides a form of recovery and gets a damage boost from Iron Fist. Mach Punch is a decently strong STAB priority move with good coverage. Knock Off hits the Ghost- and Psychic-types, including Pumpkaboo-XL, Gastly, and Slowpoke, that resist Fighting and weakens opposing Pokemon by removing their Eviolites. The final moveslot is dedicated to a coverage move. Fire Punch lets Timburr OHKO Ferroseed, and hits Foongus and Croagunk hard. Ice Punch hits Foongus, Mudbray, and Flying-types such as Vullaby, while Poison Jab OHKOes Cottonee and does significant damage to other Fairy-types. Thunder Punch is also an option to hit Mareanie and Flying-types.
Set Details
The given Attack investment allows Timburr to hit as hard as possible, especially when coupled with an Adamant nature. The remaining EVs maximize Timburr's mixed bulk. Moving the SpD investment to Spe allows it to hit 12 Speed, enabling it to outspeed Pumpkaboo-XL and Snubbull and deal significant damage to both. Timburr can run an alternative EV spread of 116 Atk / 156 Def / 156 SpD / 76 Spe with a Jolly nature to better take special hits, but it would rather not stay in against special attackers in the first place. Iron Fist boosts the power of Drain Punch, Mach Punch, Fire Punch, and Ice Punch, allowing Timburr to hit harder, while Guts allows it to capitalize on status moves to increase its power. An Eviolite is used to boost Timburr's bulk as much as possible.
Usage Tips
This Timburr set should be used as an offensive pivot, switching in when it can, regaining its health with Drain Punch, and forcing switches. Timburr's typing makes it a great Knock Off absorber, so it's able to switch in on many Knock Off users, such as Pawniard, and threaten them. Later in a match, Mach Punch can be used to pick off weakened threats. Take advantage of Timburr's coverage options to surprise would-be checks, such as Vullaby if Ice Punch is run and Snubbull and Spritzee if Poison Jab is run.
Team Options
Pokemon that can deal with Poison-type foes are essential for Timburr to perform its role. Overcoat Vullaby takes on Foongus reliably, Chinchou makes a good switch-in to Mareanie, and Abra can take on most Poison types offensively. Checks to Fairy-type Pokemon are also important, including Skrelp, Mareanie, Foongus, Ferroseed, and Pawniard. Vullaby and other bulky Flying-types offensively threaten Timburr, so switch-ins to these Pokemon, like Onix and Chinchou, synergize well with Timburr. Pursuit trappers, such as Alolan Grimer and Pawniard, can take on Abra and other Psychic-types that threaten Timburr offensively. Offensive Pokemon that appreciate Timburr's ability to counter Pawniard, such as Gastly, also make good partners. Finally, if Timburr is not running Guts, a cleric such as Snubbull or Chinchou can cure Timburr of burns, which cripple its offensive potential.
