Once during your turn (before your attack), you may attach 5 Energy cards from your discard pile to your Pokémon, except Pokémon-GX or Pokémon-EX, in any way you like. If you do, this Pokémon is Knocked Out.
Crush and Burn-GX
Discard any amount of Energy from your Pokémon. This attack does 50 more damage for each card you discarded in this way. (You can't use more than 1 GX attack in a game.)
When your Pokémon-GX is Knocked Out, your opponent takes 2 Prize cards.
