The two of the most common mutation decks are the Entropy-based 30 card deck with Druids+Photons+Life Mark, and the partially-fully upgraded FG grinding Mutation Rainbow with Druid+Otyugh+Boneyard. Your deck looks like a hash between the two, and I suggest focusing on just one if you're really gunning for effectiveness.
As for general suggestions for your deck:
Decks exceeding 37 cards in size usually have some form of draw acceleration or stalling. I suggest taking out some cards for 2 Golden Hourglasses, and adding either a Fog or Ice Shield (or even both). You could also add Sundials to your deck.
Novas are great when there are 6 of them in a 30 card deck, but once either of those numbers changes, it just goes down from there. I would suggest taking out all 5 and replacing them with Quantum Pillars. Novas are a onetime thing, and Quantum Pillars beat them out after four turns.
Quanta balance, gravity quanta specifically, is off. Elite Otyughs and Pulverizer are rather quanta hungry alone. Swap an Elite Otyugh out for a Parasite - Parasites are rather underrated and good at what they do; they're cheap, so you have a better chance of getting it out; even if it's flimsy, it triggers Boneyards when it dies, so you don't lose out completely.
Whatever changes you make, try to keep it under 40 cards if you can.
