Your deck is truly screaming for more Afla. A death nymph would go great here.
Also, nice choice on the sanctuary and spine carapace on the second deck - it lets stuff wonder around the cells unharmed.
Btw, Y U NO flooding? Flooding does not kill the cells, and you will use Chimera on the turn you fractal the Vultures, and even then they will still dmg even if you don't. Though they will die then.
