Vaporeon-GX

Once during your turn (before your attack), you may heal 30 damage from your Active Water Pokémon.

This attack does 30 more damage times the amount of Water Energy attached to this Pokémon.

Heal all damage from all of your Water Pokémon. (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.
