Predestination by Gary Jones

Gary Jones has got a trick here that's about as easy as breathing. It's self-working, which means you can basically sit back and watch even the experienced magicians look a bit confused.

Here's the setup:

You whip out some picture cards and mention a joker with a secret scribbled on its back. The joker takes a little break on the side. Then you show two picture cards at a time, letting the spectator pick whichever they like while they note it down. It's genuinely their choice, no smoke and mirrors on that front.

After four picks, you flip over the joker to show you had their choices pegged from the start. Why it works so well is anyone's guess, but it does, trust me.

Comes with everything you need, and you'll get a handle on it quicker than you can make a cup of tea. It's ready when you are. Just remember, don't be too smug when it all pans out.
