Any ideas on how to cut it down? I took out 3 of each card but then I would die before I would be able to get a good amount of posion out.
Well, you're trying to do too many things at one time for 1. also you have supernovas/quantum towers but are only using a few elements. The combination on quantum/novas should be at least 15 here if not more. Also balance your quant usage more if you want a rainbow, you're very heavy on death quanta usage. Maybe add hourglasses, PC, CC if you want to stay rainbow.
Personally, I would make this a duo/trio and focus more on 1 or 2 things.
