Trevenant & Dusknoir-GXオーロット&ヨノワールGX

At the end of your opponent's next turn, the Defending Pokémon will be Knocked Out. If this Pokémon has at least 1 extra Psychic Energy attached to it (in addition to this attack's cost), discard all Energy from your opponent's Active Pokémon. (You can't use more than 1 GX attack in a game.)
