No Entry

A very clever and totally baffling card effect.  
Effect 
Any card is freely selected  signed and lost in the deck (really lost  no control the signed card is replaced anywhere) Two jokers are removed from the deck and a previously examined paper clip is put on the two jokers fastening them together. The two jokers are placed to one side  there are genuinely only two cards.  
The spectator tries to cut to their signed card but fails. The two jokers are picked up and shown on both sides  they are still fastened together with the paper clip.  
The paper clip is removed. The two jokers are spread  but now there is a third card trapped between them  the spectator removes this card it is their signed card. 
A very easy and brilliant principle that you will love to do. 
Comes complete with special gimmick and full instructional DVD.
