This was a lot of fun to play with, and a couple gods are much easier. However, i think the queen turns around more matches than the nymph does, whereas the nymph is only usually useful when you're already in control of the match, with just a very small handful of exceptions.
Building up 12+ air quanta early enough in a match to control the board is not really feasible for a rainbow unless your mark is air. Maybe if i had 2 air nymphs just to increase their draw rate, i could justify changing my mark and tweaking the deck to compensate, but just 1 nymph that isn't very good against 5 or so gods is just not effective. Besides, entropy or time mark are both extremely effective against every god in *all* situations, so i think its a wash.
If i had several air nymphs, i do believe i could make a god grinder that skips certain gods, kind of like how nymphomania works, but getting several air nymphs is a long ways off.
Very fun and interesting alternative, but as puppy mentioned, its not better.
