Is this will be a golem?
if so, it's seems to be very potent in that deck.
But comparing to the other card generating cards, it's strong, clearly in upped. In SoSep, you can't really know how useful it will be, Alchemist need a lot of type of quanta to be useful, but this is mostly reliable (2 card out of 6-10) and in some element you nearly never can get useless card, especially in
, where you can get Unsummon, Twin Universe, Silence, or Fractal. So, in most case (~67%), it's lets you to play an another Lab golem. Optionally it could become a 4|3 psionic immortal from one card (Okay, ~4.1% is not that high).
So I find Mitosis synergy secondary (like, it can be killed before it's starts Mito-ing itself), I find more problematic the Aether version.
