Naganadel & Guzzlord-GX #260

Turn all of your Prize cards face up. (Those Prize cards remain face up for the rest of the game.) If this Pokémon has at least 1 extra Psychic Energy and 1 extra Darkness Energy attached to it (in addition to this attack's cost), take 2 Prize cards. (You can't use more than 1 GX attack in a game.)
