Once during your turn (before your attack), if your opponent has 4 or more Benched Pokémon, you may choose 1 of them and shuffle that Pokémon and all cards attached to it into his or her deck. This power can't be used if Dusknoir is affected by a Special Condition.

Put 5 damage counters on the Defending Pokémon. Then, count the number of Prize cards your opponent has taken and put that many damage counters on the Defending Pokémon.
