Assist

Uses a move from another Pokémon in the user’s party, both selected at random. Moves from fainted Pokémon can be used. If there are no eligible Pokémon or moves, this move will fail. This move will not select Assist, Chatter, Circle Throw, Copycat, Counter, Covet, Destiny Bond, Detect, Dig, Dive, Dragon Tail, Endure, Feint, Fly Focus Punch, Follow Me, Helping Hand, Me First, Metronome, Mimic, Mirror Coat, Mirror Move, Phantom Force Protect, Quick Guard, Roar Shadow Force, Sketch, Sleep Talk, Snatch, Struggle, Switcheroo, Thief, Trick, Whirlwind, or Wide Guard. This move cannot be copied by Mirror Move, nor selected by Metronome or Sleep Talk.

The appeal’s quality depends on its timing.
