Abilities & attacks
ITEM
Once during your turn (before your attack), if you have Unown I, Unown T, Unown E, and Unown M on your Bench, you may search your deck for a Trainer card, show it to your opponent, and put it into your hand. Shuffle your deck afterward. You can't use more than 1 ITEM Poké-Power each turn.
Hidden Power
Choose an Energy card attached to the Defending Pokémon and put it face down. Treat that card as a Special Energy card that provides Colorless Energy and doesn't have any effect other than providing Energy. Put that card face up at the end of your opponent's next turn.
