Once during your turn (before your attack), you may search your deck for any Castform and switch it with Castform Snow-cloud Form. (Any cards attached to Castform Snow-cloud Form, damage counters, Special Conditions, and effects on it are now on the new Pokémon.) Shuffle Castform Snow-cloud Form back into your deck. You can’t use more than 1 Temperament Poké-Power each turn.
