You must discard a Basic Grass Energy card from your hand in order to use this Ability. Once during your turn, you may put 3 damage counters on 1 of your opponent's Benched Pokémon.

If your opponent's Active Pokémon already has any damage counters on it, this attack does 120 more damage.

Pokémon ex rule: When your Pokémon ex is Knocked Out, your opponent takes 2 Prize cards.
