the Council and the Revisionists should both have a starting cohort, and I'll make an update fairly soon that fixes them. Feel free to define as you wish for now, but I'll be giving the Revisionists an Expert (who the crew then gets to define) while the Council will start with a Cohort of Tracers (I'm aware that this will result in a "control" council start that gives them 2 starting gangs, the intent is to use my post-update bug-fix update bring the Black Hats and Dynasty up to the level of the two new crews by giving them an additional choice of bonus at creation).
Yeah, the inversion lab wording change was mostly to try to explain how a player would even go about using it in the game. It's tough with the word count in the claim bubbles, but I still want to allow it to do fun things like you propose. I'll try to figure out a way to leave it open- ended while also prompting the imagination.
