1. Mark is obviously Entropy, yes?
2. You can safely go down to ~7-8 Quantum Towers without too much of a problem when you're running Supernovas.
3. Schrödinger's Cat is sort of weak and redundant, since you already have FFQ and Boneyard to pump out creatures to mutate/devour as needed. You could experiment with using the Cat instead of FFQ to generate creatures with Boneyard and strengthen Bone Wall.
4. Aflatoxin and Fractal sort of seem tacked on, as you already have high quanta usage from the main combo cards in both
(Boneyard, Bone Wall) and
(Quints) already.
5. Use more Hourglasses. A general rule of thumb for Hourglass counts in FG-rainbows is 2 Hourglasses for 35 cards or fewer, 3-4 for ~40 cards, and 5-6 for 45+ cards or so.
