I'd remove:
Both Novas
Momentum
Chaos Power
Precognition
Ray of Light
I agree with this, but to add on:
-one dimensional shield is far too luck-reliant for my liking. Chances are you'll either not draw it when you need it, or have a better shield out (like bone wall), so either add another dimensional shield or 2, or replace it with a second bone wall.
-You may want to remove some sundials, because they don't seem to pull their weight after the nerf, from my experience.
-I would suggest adding in either a second bone wall or another good shield (my suggestions for the other shield are jade shield (that's the upgraded green one) because it can't be destroyed/stolen and prevents 2 damage, or a diamond shield because it prevents 3 damage, or a permafrost shield)
-i'm still just experimenting with it, but you could try replacing boneyard with aflatoxin, or just adding aflatoxin (but it does conflict with other high-cost cards in terms of quanta) because it gives you something really good to reverse time with eternity, and a constant supply of creatures to devour/mutate
-also another quintessence or 2 wouldn't hurt (especially if you remove the dimensional shield)
