Ability Twilight Eyes
When you play this Pokémon from your hand to evolve 1 of your Pokémon during your turn, you may discard an Energy attached to your opponent's Active Pokémon.
This attack does 30 damage for each Energy card in your opponent's discard pile. (You can't use more than 1 GX attack in a game.)
When your Pokémon-GX is Knocked Out, your opponent takes 2 Prize cards.
