I made a really boring deck with 5x jade dragon, 5x mitosis, 5x shard of readiness, 2x thorn carapace, some heals, and pillars/pends. It went 10-2, but that's probably about what your charger mitosis deck will get, I'd think. Yours might even do better. Maybe use Titan instead of Massive Dragon; it's cheaper and it has momentum, though it is vulnerable to permanent removal, and since you have no permanents except towers, it will draw removal like a magnet.
Also, I hope you have double or triple mark with that, otherwise you'll need gravity pendulums.
