Once during your turn (before your attack), you may discard an Ultra Beast card from your hand. If you do, draw 3 cards.
Discard 2 Energy from this Pokémon. This attack does 170 damage to 1 of your opponent's Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
Add a card from your opponent's discard pile to their Prize cards face down. (You can't use more than 1 GX attack in a game.)
Pokémon-GX rule: When your Pokémon-GX is Knocked Out, your opponent takes 2 Prize cards.
