Electrode GX

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.

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.)
