Huh.
I wonder what kind of deck you're going for.
Seriously though, try to make your nymphs less.... random.
Going for green nymphs every time gives you pillar limited adrenaline spam. Going for red nymphs can combine with guardian angels for an infinite attack loop. Going for dark/entropy nymphs makes his creatures work for you. Going for gravity nymphs obliterates his quantums. Going for time nymphs speed your deck up alot. Going for aether nymphs gives you immortals.
Going for random nymphs just causes problems........ oh screw it that looks like an awesome deck. Might have issues getting water quantums though, I'll try it in the trainer.
Okay back. Some improvements:
Replace two quantum pillars with nymph's tears. Replace the ice bolts with anubis's. Replace both ice bolts with more water quantums. I spent the whole game waiting to get nymphs out, only to have the computer kill them easily. With this set up you'll have a safe source of immortality, back up blue nymphs, and you won't get pillar draws all game. Take an eternity too if you can, it'll save your butt once you get a grey nymph. Near the end game you start to run out of pillars, swap all your novas for quantum pillars to stop that if you want.
Your main issue is speed. The deck simply can't get going fast enough. It's a great concept, but it needs some work =/
