Cacturne

Choose 1 of your opponent's Pokémon that has any damage counters on it. This attack does 50 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)

You may discard a Grass or Darkness Energy attached to Cacturne. If you discard a Grass Energy, the Defending Pokémon is now Poisoned. If you discard a Darkness Energy, the Defending Pokémon is now Paralyzed.
