Rotom

Poké-PowerMischievous Trick

Once during your turn (before your attack), you may switch 1 of your face-down Prize cards with the top card of your deck. This power can't be used if Rotom is affected by a Special Condition.

Choose 1 of your opponent's Pokémon. This attack does 20 damage for each Energy attached to that Pokémon. This attack's damage isn't affected by Weakness or Resistance.
