Mega Sableye & Tyranitar 

If your opponent's Pokémon-GX or Pokémon-EX is Knocked Out by damage from this attack, take 1 more Prize card.

If this Pokémon has at least 5 extra Energy attached to it (in addition to this attack's cost), discard the top 15 cards of your opponent's deck. (You can't use more than 1 GX attack in a game.)
