I'd check out this guide by my mate @BitterSteel. He really breaks it down quite well and he's done some awesome stuff with his Professor X!https://forums.playcontestofchampions.com/en/discussion/256739/professor-x-in-depth-how-to-use-guide#latest
The best rotation is dropping suicides. I'm a 100% suicides player (My roster reflects it. It's a non-traditional set-up) and I simply can't play Prof X with them on. So he sits unawakened on the bench. Curious to see the answers to the OP's question because I do like the champ but I'm currently looking for any rotations that help me as a suicides guy with this champ.
