Celesteela-GX

This attack does 30 more damage for each Colorless in your opponent's Active Pokémon's Retreat Cost.

Turn all of your Prize cards face up. (Those Prize cards remain face up for the rest of the game.) (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.
