PoliwrathニョロボンUnlimited

Poké-PowerStrange Spiral

Once during your turn (before your attack), if Poliwrath is your Active Pokémon, you may discard a basic Energy card attached to Poliwrath. If you do, the Defending Pokémon is now Confused. This power can't be used if Poliwrath is affected by a Special Condition.

Flip a coin until you get tails. This attack does 40 damage plus 20 more damage for each heads.
