Mystery Plate δ

Healing Oasis

If your opponent has 5 or more Prizes, search your deck for up to 3 basic Energy cards, show them to your opponent, and put them into your hand. Shuffle your deck afterward. If your opponent has exactly 2 Prizes, remove all damage counters from 1 of your 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 δ.
