As often as you like during your turn (before your attack), you may attach 1 Energy card to 1 of your Pokémon. (This doesn't use up your 1 Energy card attachment for the turn.) This power can't be used if Blastoise is Asleep, Confused, or Paralyzed.
Does 40 damage plus 10 more damage for each Energy attached to Blastoise but not used to pay for this attack's Energy cost. You can't add more than 20 damage in this way.
