Aside from the quantum towers and supernovas, each cremation could fuel a fire spectre for 9 turns, so you have a lot of fire quanta unused... how about adding minor phoenixes and getting rid of the photons and spectres? (which are very poor)
Then, since it's mainly a buff deck, you could test with some blessings and chaos power in the trainer, along with something to speed up the draws
Another interesting option you have is getting rid of fire/photons and making it a deja-vu speed deck. Here's mine, hope this helps...
