Wow.....
I stand in awe mog!
I'd love to be able to do a false riffle shuffle like that, but believe you me, if I could I would! I spent about 10 minutes on the zarrow shuffle and I didn't even do one right, let alone invisible. The shank shuffle seemed a bit too obvious to me - but then spectators can be unusually obtuse sometimes (and it was done excellently

). And the third shuffle...wow, wow, wow!
You're brilliant mog!
Do I get away with my pitiful variant? I don't know. As I mentioned in another post, nobody's ever called me on it. However, spectators do have a tendency not to mention if they see something, so they may well have noticed and just not said anything. They did seem to like the effect though...(emerge triumphant...).
