Attach this card to 1 of your Pokémon in play. That Pokémon may use this card's attack instead of its own. At the end of your turn, discard Mystery Plate β.
If your opponent has 5 or more Prizes, draw 3 cards. If your opponent has only 1 Prize, choose 2 Energy cards attached to the Defending Pokémon (1 if there is only 1). Your opponent shuffles those cards into his or her deck.
