This is a full-fledged, three-phase routine from Pit Hartling's excellent book. It is full of fantastic card magic. A small book , but it packs serious punch.
David lessened the routine overall, I felt, by reducing it to a one-trick pony. However, props to him (or whoever's idea it was) to have the spectator flick the deck. In the years I've been performing this routine I never thought to try it. Excellent idea.
