Permanent blanket effects massively slow down AI response time

[P-rus]

There are a number of cards that are impossible to play, not because of bugs but, because changes to card type or timing definitions cause the AI to take much longer to hash out the choices. So far the cards that seem to do this are:
-Teferi, Mage of Zhalfir
-Mycosynth Lattice
-Enchanted Evening
-Teferi, Time Raveler

I understand discovering/fixing these issues would be problematic. Barring that, would it be possible to simply have an AI bypass function on the Dev menu to shut off AI function and/or allow manual control of the NPC's? What I have been doing is spawning Mindslavers to control the AI, but that's getting a bit tedious.
