Upon watching the trailer I immediately thought of Inferno by Joshua Jay, though with a different presentation. I've performed Inferno for some time now, and while it is an excellent trick, this just looks more streamlined and straight to the point. Less props, less storytelling – compared to Inferno – but with the same great reactions. How similiar are these tricks? Also, can another spectator hold the card throughout the routine? And does the magician have to reveal the card, or can it be folded up by a spectator?
