Once during your turn (before your attack), you may discard a basic Energy card from your hand. Porygon-Z is the same type as that Energy Card until the end of your turn. This power can't be used if Porygon-Z is affected by a Special Condition.
Flip 3 coins. This attack does 40 damage times the number of heads.
