This is a great trick...if you practice practice practice. The concept is wonderful but it uses a
very angle sensitive move. This is definately not for beginners. I would say this trick is good for
about 3 people but no more than that. Once you get this trick down, it's pure awesome. You can even
ask what their birthday is and their card is at that number from the top. Pretty cool. As a magician
you might not be that satisfied with the method, but to the audience it is absoutely amazing which
is all that matters. If you think you could use this trick then get it!
