Search your deck for up to 3 basic Energy cards and attach them to your Pokémon in any way you like. Then, shuffle your deck.
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.)
