Naganadel & Guzzlord-GX

Once during your turn (before your attack), you may discard a Pokémon from your hand. If you do, heal 60 damage from this Pokémon.

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 {P} Energy and 1 extra {D} 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.)
