Mutation is more a control Spell, while Improved Mutation is awesome to use in your creatures. Unupped fallen elves don't work that well.
Being a deck with more than 30 cards makes it harder to draw the creatures you want. Also, you don't have so many creatures to use the Bonds effectively. I would rather go for CC instead of healing.
You WANT 6 photons and 6 Sparks or Deja Vus to have many mutants. If you feel you have the quanta, go for Photon + 2/3 Mitosis.
Lastly... quantum pillars, no Novas. This isn't a rush and the pillars will be more effective.
