The user copies the target’s last move. The move can be used during battle until the Pokémon is switched out.
This move is replaced by the target's last successfully used move, and its PP changes to 5. If the target hasn't used a move since entering the field, if it tried to use a move this turn and failed, or if the user already knows the targeted move, this move will fail. This effect vanishes when the user leaves the field.
