Trancentwist by Peter Pellikaan

The problem with packet tricks, as we see it, is that the plots are too confusing. What makes "Transcentwist" so great is that you sit back and watch as very simple, direct magic starts unfolding. The backs of four Queens change from black, to orange, to purple, to green. When all of the cards are turned over one last time, they have changed into Aces, each one with a different-colored back. Stunning!What's even better is that the packet effect is so easy to perform. You make up the cards yourself. You'll need 4 different colored backs, and a roughing stick or some sort of roughing solution.
