Yveltal GX (79/131) - [SM: Forbidden Light] Holofoil

Heal from this Pokémon the same amount of damage you did to your opponent's Active Pokémon.

This attack's damage isn't affected by Weakness or Resistance.

If your opponent's Active Pokémon has exactly 4 damage counters on it, 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.
