Retro Cave [Colorless]: If your opponent has 5 or more Prizes, shuffle your hand into your deck and then draw 6 cards. If your opponent has exactly 2 Prizes, choose 1 of your opponent's Evolved Pokémon. Your opponent puts the top card on that Evolved Pokémon on the bottom of his or her deck. (This counts as devolving that Pokémon.)
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 γ.
