I tried forever to make a FG deck with air nymphs and couldn't figure out how to get it done with even a meager winrate. I started by using tears and wind towers but then decided to see if I could even win if I had blue nymphs in trainer and I failed. And I don't think you'd be able to create a more efficient t50/AI3 deck, as blue nymphs are slow. My current opinion is that nymphs are relatively useless collectors items.
If you were shooting for an upped pvp deck or something, I'd start by trying:
Mark of Fire
16 wind towers
3 explosions
6 gas
2 nymph
2 fog
2 eagle eyes
Of course, that deck's hot garbage against mirror/jade shields.
Whatever you do, I'd definitely throw in all of your shards of readiness.

And let us know if what you try works!
