Darkrai GX - 88a/147 - Alternate Art Promos Holofoil
Once during your turn (before your attack), if this Pokémon is in your discard pile, you may put it onto your Bench. Then, attach a Darkness Energy card from your discard pile to this Pokémon.
This attack's damage isn't affected by Resistance.
If your opponent's Active Pokémon is affected by a Special Condition, that Pokémon is Knocked Out. (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.
