D.I.E. by Sirus Magic

A spectator's card is chosen randomly, by the throw of a paper dice. They can throw as many times as they like. When they are happy with the number, they will count from a deck, to that number, to choose a card. When they have their card, they will be very surprised to find, that the dice was influencing them the whole time, without realizing, The Die itself, when unfolded, is made from a matching duplicate of the card they "freely" choose!
Based on a revamped 30+ yr old principle, this simple (for the performer) yet effective principle allows the spectator or any number of spectators to get involved, seemingly do all the work, and yet still create a miracle revelation at the end of the effect.
