Marshadow-GX

This Pokémon can use the attacks of Basic Pokémon in your discard pile. (You still need the necessary Energy to use each attack.)

This attack does 50 damage times the amount of basic Energy attached to this 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.
