ARBITRIUM  combines a Double Prediction with Any Card At Any Number (ACAAN) into a compelling and easy to follow plot that baffles audiences.

The performer removes a mystery, odd-backed lucky card from his wallet and isolates it, then two decks are introduced- a number deck and a standard deck of cards. Both decks are spread for the spectator to choose ANY card from each (they really do touch any card from each deck!). Next, instead of a tedious counting procedure found in most ACAANs, the performer retrieves the isolated lucky card, which is then turned over to show its not only a perfect match to the freely selected card, but it also has the chosen number permanently drawn across it! An exact coincidence- proving that it truly is a lucky card! 

Key Points:

• The description above is how the effect plays out every time (no "best case scenario")
  
• Very practical method
  
• Easy to do
  
• Resets in under 10 seconds
  
• Multiple versions taught, including variations with just one deck
  
• Can be adapted to a variety of other creative ideas aside from cards and numbers (such as names, drawings, colors, etc.)
  

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

"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

Note: There is a one-time, easy DIY construction to setup the decks for the effect, which uses materials that most magicians likely already have.
