You may have up to 4 Basic Pokémon cards in your deck with Unown in their names
Once during your turn (before your attack), you may search your deck for another Unown and and switch it with Unown. (Any cards attached to Unown, damage counters, Special Conditions, and effects on it are now on the new Pokémon.) If you do, put Unown on top of your deck. Shuffle your deck afterward. You can't use more than 1 Shuffle Poké-Power each turn.
Search your deck for up to 2 Pokémon Tool cards and attach them to any of your Pokémon (excluding Pokémon that already have a Pokémon Tool attached to them). Shuffle your deck afterward
