I held back one star only because you can't truly demonstrate that the deck is mixed (ie. with a
shuffle) and on my third ever demonstration of this effect, I had a lay person ask a question about
the deck (which I won't say here for the sake of protecting the secret), but their guess was right.
I of course avoided answering truthfully and instead pointed out that they had cut the deck as many
times as they liked and still selected six separate numbers. A fun trick with friends...likely will
not use this in any of my professional performances.
