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 PokÃ©mon.) If you do, put Unown on top of your deck. Shuffle your deck afterward. You can't use more than 1 Shuffle PokÃ©-Power each turn.
Hidden Power 10
Choose 1 of the Defending PokÃ©mon's attacks. That PokÃ©mon can't use that attack during your opponent's next turn.
