For the rest of the game, your Pokémon's attacks do 30 more damage to your opponent's Active Pokéon (before applying Weakness and Resistance). If this Pokémon has at least 1 extra Energy attached to it (in addition to the 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
