Unfortunately, that screws up your ability to MC them and make them eat/wear stuff. I guess you could make it a race when they wake/rest. Apply the mind control, plant the item, then have a trigger to suggest when they wake/rest. But a lot of people would still beat you. That makes me want to skip MC altogether and just use the points in some other path.
Also, I'd thing not having gag would suck for poisoners, since it's their only good way of preventing people calling for help. If you're planning to be a scroll-abusing poisoner, seems like you need a lot of time to work your mojo, which you "usually" wouldn't be allowed.
