Was searching for something that checks Charizard-Y and Tapu Koko for Aurora Veil Volcarona Hail that's not affected in a bad way by Tapu Fini's Misty Terrain (e.g. Dragalge). Turns out, such a thing really exists. With the plethora of resistances, covered by an Aurora Veil, you can just go fire off them Shadow Bones.
