ARBITRIUM is an incredibly powerful double prediction effect that leaves audiences baffled- including magicians!

Imagine placing a lucky card, your prediction, in your pocket. You then bring out two decks, one with numbered cards and one standard deck. The spectator makes an actual free choice from each deck, selecting one number and one playing card. You then remove your lucky card to show its not only a perfect match to the freely selected card, but it also has the chosen number boldly drawn on it! An exact coincidence -- proving that it truly is a lucky card!

The 50-minute video download covers multiple variations, including versions with just one deck. You will also learn how to adapt it to a variety of other creative ideas (such as names, drawings, colors, etc.). You will also find a bonus video that shows how using a common utility device can even further enhance the routine. Better yet, you'll discover how easy this is to do, how easy it is to reset, and how very practical the handling is.

Here are a few quotes from reviews over at The Magic Cafe:

"This is a very practical to perform, strong, deceptive effect and it uses a nice marriage of principles to make it all work."
– Matt "Mayavi" Packard

"Well structured and thought out routine. An effect I predict that all, or at least most, will use if the ACAAN plot is your thing.... It won't end up at the bottom of a magic drawer... Recommended!"
– Rizzo

“It is obvious that David has worked this as it is a well conceived set of principles that come together beautifully. The selection of the card is actually devilishly brilliant and will seem incredibly fair to any spectator. If you like what you see in the trailer, this is a no brainer.”
– Jason L

"If you have no issues with doing a one-time setup and carrying two decks specific for this effect, then this is a very interesting piece that is guaranteed to floor spectators"
– ash2arani

Please note that there is a one-time, easy DIY construction to setup the decks for the effect, which uses materials that most performers likely already have.
