Maybe switch out a life nymph for something? I know they're an important part of the deck strategy, but are you really going to have enough quanta to play all 6 of them?
Overall this deck looks really great, though I doubt many people will have the nymphs necessary to play it xD Also, I think the nymphs can be left unupped. If I'm not mistaken, upping them just increases stats, and most people who have nymphs don't up them.
