David has taken the Duel Match premise to incredible new heights with a complete change of method.
By rolling two dice, your spectator generates a random number. You cleanly count to this number from either end of a rainbow deck and remove their chosen back design.
The deck is now completely spread to show that there really is only one card with this unique back design. The dice are rolled again and once again the cards are counted from either end of the deck to arrive at a random value. The deck is completely spread to show absolutely no duplicates are in play.
In essence, your spectator has created a random playing card from these two free selections. You now ask him to open an envelope that has been sitting in view from the very beginning -- inside is a perfect duplicate of the card that has been created.
Your package comes complete with a very special custom deck, two beautiful dice and full video tutorial. Fortuity is so easy to do; even a beginner could do it with only a few minutes of practice.
No Loaded Dice, any numbers can be rolled (or use imaginary Dice)
All the cards can be shown both front and back
Absolutely Zero Sleight of Hand
