The Annoying Doubles Garchomp that Could
IRS Agent (Garchomp) @ Focus Sash/Groundium Z/Assault Vest
Ability: Sand Veil
EVs: 252 Atk / 252 Spe / 4 SpD
- Rock Slide
- Dragon Claw/Poison Jab
- Swords Dance/Protect/Poison Jab
This one's a fun one for doubles. The premise is simple: abuse Sand Veil with something carrying Sand Stream, and then use Earthquake and Rock Slide to your heart's content. It makes a good partner with Flying types, the Sand Stream setters, and Vikavolt+Garchomp creates a very nasty DisQuake combo.
Earthquake and Rock Slide don't even need explanations. Stone Edge is another option, but for the sake of annoying an opponent, hitting both enemies with a nasty flinch chance is better. Dragon Claw is reliable STAB, and Poison Jab can give an unexpected smack to Fairy types. Swords Dance allows Garchomp to reach obscene levels of power, and Protect is a mainstay in Doubles. Focus Sash allows Garchomp to take multiple super effective hits before dying, Groundium Z gives Garchomp a terrifyingly strong Tectonic Rage, and finally, Assault Vest gives Garchomp some nice special bulk, though you can't use Swords Dance or Protect with it. Max Speed allows Garchomp to outspeed many crucial threats, courtesy of its 102 Speed stat naturally outrunning base 100s.
