Bulky Hazard Controller
Baltoy @ Eviolite Ability: Levitate EVs: 196 HP / 196 SpD / 116 Def Calm Nature IVs: 0 Atk - Rapid Spin - Stealth Rock - Psyshock - Rest
This mon serves as a hazard clearer and a hazard setter at the same time. Rest is for recovery with the cost of 2 turns asleep. Its Eviolite-boosted bulk makes STAB Psyshock stronger as it uses its special defense stat to attack, and Baltoy's special defense is the best thing about it. It's nice ability and decent typing makes it immune to 2 types. Rapid spin so it can clear hazards for the team. Hope you like this moveset :).
