Personally I'd have slightly more water pillars (about 6-8 total because you want your 1st nymph to be a queen ideally), 2 quintessense (because quinting a queen can really make a massive difference against some opponents) and 2 Pulverisers for PC. To be honest, I'd personally have all towers instead of Supernovas, because you can't turn a Snova into a nymph. This is personal preference, however.
