Quaquaval Promo = Quaquaval EX
Rapid strike energy = Reversal Energy
Deck Idea : Use Quaquaval to attatch energy to your Quaquaval EX, then return those energies to your hand during your turn. Irida pieces this deck together by allowing you to grab rare candies or Lumineon V/Pyumuku/Radiant Greninja for extra draws.
Edit: I would reccomend adding a copy of superior energy retrieval and super rod in the deck.
