SINK Them with JB Magic's SHIP Deck!   Instructional DVD Included with Ship Deck!  You claim that  you have a prediction.  The 4 aces are removed from a RED deck and placed off to one side.  The spectator is asked to  THINK of ANY card, NOT the SUIT just the VALUE.  Lets assume they are thinking of a 4.  Next they are asked to mix the four aces, these are laid out in a row.  Each ace represents each suit, they select any one of the four aces NO FORCE etc.  They pick just one ace and that card's suit is used. Lets say they pick hearts.   In a fair manner they've now selected the 4 of hearts.  The SAME deck is spread across the table, face down.  In the deck there is now one card face up and one card only.  It is the 4 OF HEARTS!  The 4 is removed and flipped over it is the ONLY card with a BLUE back in the RED deck!
Sounds & Looks Impossible, NOT with Ship deck! Instructional DVD Included with special Bicycle Deck.
