This is almost a great effect. Fairly easy to do, and it really does baffle people. I just wish
there was some way to clean up the presentation and make the "behind the back" part feel less
awkward. So far, I haven't come up with any ideas.
I also think the "blank reveal" should
be eliminated. In my mind, this provides symmetry to the two reveals that could lead a smart
spectator back to the method. I just don't think it's worth it. The first reveal is strong enough
as it is.
The bonus materials are pretty good, however they're not different enough from
the main effect to be considered "additional" effects. They're more like optional variations. "The
Amazing Four Aces Trick" is particularly good, but it does require a pretty good amount of prep.
However, I think it's worth it because it hits just as hard, it adds some humor, and the book
provides the requisite cover that allows you to avoid having to go behind your back with the cards.
