Disable

Disables the target’s last used move, preventing its use for 4–7 turns, selected at random, or until the target leaves the field. If the target hasn’t used a move since entering the field, if it tried to use a move this turn and failed, if its last used move has 0 PP remaining, or if it already has a move disabled, this move will fail.

“For four turns, the target will be unable to use whichever move it last used.”
