There's a good chance you've recognized something 'clockish' about this trick, and you're correct.
This is however a very original variation and Astor is a brilliant thinker, so it's a good one. He
teaches an original deck stack that makes the trick almost completely self-working. The wheel prop
is neat idea, interesting in appearance which is always good, and comes with a nice plastic sleeve
to keep and transport it in. Provide your own deck. His accent is strong and some parts I had to
listen hard to understand. It helped that I knew the 'clock' principle so if you're interested in
this, maybe do an online research of the principle first, which will make understanding the dvd
easier. 5-stars for Astor originality of a classic principle.
