Fairy crushing Toxicroak:
Toxicroak @ Expert Belt
Ability: Poison Touch (Dry skin if in a rain team)
EVs: 252 Attack, 252 Speed, 4 HP
Swords Dance/Sucker Punch/Rain Dance (for rain teams)
I came up with this while making a fighting type team. Poison Jab for STAB fairy removal, and EQ because every fairy is weak to poison or ground. Brick Break is for more STAB, and sucker punch to cover psychic. Swords dance boosts attack further. Rain Dance boosts Dry skin Toxicroak's HP.
