Unown

Choose a card from your hand and put it face down. You opponent guesses if that card is a Pokemon, Trainer, or Energy card. Reveal the card. If your opponent guess wrong, draw 2 cards. Put the card back into your hand.

Poke-POWER Shuffle

Once during your turn (before your attack), you may search your deck for another Unown and switch it with Unown. (Any cards attached to Unown, damage counters, Special Conditions, and effects on it are now on the new Pokemon.) If you do, put Unown on top of your deck. Shuffle your deck afterward. You can't use more than 1 Shuffle Poke-Power each turn.
