I read the description and was positive I knew the method. I wasn't going to buy it. Then I watched
the trailer, and I was stumped. I had to know how it worked. I got it and had that "a-ha moment." As
with all of Gary's stuff, this is straightforward but completely baffling. It uses a principle found
in a couple of commercial gimmicked decks, but you don't have to buy them. You can make this up
using regular decks.
This is an excellent card/mentalism effect like Max Maven's Predixion.
I recommend it highly.
