The Fan Control is actually one of my favorite controls. It's simple, deceptive, all that jazz... what more could you want? But I still use things like a Double Lift, Pass ,Tilt, etc. But one of the best controls, and similar to Fan Control in the fact that the spectator can shuffle the deck as much as they want, is just Top Palming their card off the deck and having them shuffled them up. Then take it back and add it to the top. But I've never actually used this in a performance- I'm not that comfortable with palming yet.
