This is incredibly simple to do once you have to move down -- since it's the only move in the trick.
I changed it a bit though, so it doesn't use blank cards. My version is to write "NO!" on
every other card, so that the hand that they choose is the only card in the deck without "NO!"
written in big black lettering across the face.
Overall, this is genius and I'm going to be
performing it with my own style all night tonight at my show!
