This from my 7 Gods game thread (
http://elementscommunity.org/forum/index.php/topic,21129):
I'd like to know what happened in that game vs. Primordial Soup, RR. I've noticed some strange situations in which having a couple of Rustlers with Mitosis seems to make the AI not activate the (spawned) Rustler's Photosynthesis -- I thought it was a problem with Rustler, but it looks like it might have happened to you with Viruses. If that's the case, it's a problem with Mitosis, not Rustler.
Yes, mitosis is probably linked to this. A possibility is that the AI did not want to activate mass creature control until I have more than two creatures. This is what I originally thought, thus, I didn't play my Elite Queens or Otyughs. But if you have the same problem with mitotic rustlers then the problem most likely be mitosis. Also, the original retrovirus with mitosis was the first creature played, if that might effect anything. Some of the retroviruses were played from the hand and still did not use their ability.
The pattern seems to be that once there are 2 or more creatures with Mitosis on the enemy field, it simply declines to use any active skills whatsoever.
