PokÃ©-Power Jet Stream
Once during your turn (before you attack), if Blastoise is your Active PokÃ©mon, you may flip a coin. If heads, discard an Energy card attached to Blastoise, if any. Then, if there are any Energy cards attached to the Defending PokÃ©mon, choose one of them and discard it. This power can't be used if Blastoise is affected by a Special Condition.
Energy Cannon 40+
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.
