Haxorus @ Leppa Berry
Ability: Unnerve
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Outrage
- Fling
- Earthquake
- Poison Jab
Heck, the SpD and most Speed EVs aren't necessary
Leppa Berry for if the Whimsicott Protects 16 turns in a row
Fling because it works well with Leppa
Adamant because it is a good vocabulary word
Mold Breaker because it goes through abilities such as Prankster and Air Balloon
Outrage Kills (Often enough for this set to be suggested) Haban Berry if you really want to guarantee the win. I don't like Haban because I want to ensure the Whimsicott Matchup
