Altered Creation-GX
For the rest of this game, your Pokémon's attacks do 30 more damage to your opponent's Active Pokémon (before applying Weakness and Resistance). If this Pokémon has at least 1 extra Water Energy attached to it (in addition to this attack's cost), when your opponent's Active Pokémon is Knocked Out by damage from those attacks, take 1 more Prize card. (You can't use more than 1 GX attack in a game.)
