I was looking/hoping for a streamlined version of the all-slights presentation. Instead, this is a
clearly, pedantically clearly, explained version that uses a gimmick.
It will play will
for laypersons and there is a discussion of how to bring the gimmick into and out of play. Still,
it is not as strong as if you were able to do it instantly with someone else's cards.
Also,
the Penguin listing talks about performing this with business cards. That is never explained and is
unlikely to be at all practical given the method presented.
Finally, while the gimmick is
not provided with this effect there is some discussion about how you can come by one, either with
included in another purchase or making it yourself. And, even though I've been making them for
years there was something mentioned that I hadn't tried yet and may make their preparation even
easier.
That said, the presentation is clean and I like that the trick can involve
multiple spectators in a way that makes them look good.
