Aerodactyl-GX

As long as this Pokémon is your Active Pokémon, your opponent's Basic Pokémon's attacks cost Colorless more.

This attack does 50 damage times the amount of Energy attached to your opponent's Active 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.
