You give a spectator the four Kings while you retain the deck. The spectator mixes the Kings and lays them on the table. You give the deck a cut stating that your task is to try to cut to the Queens—the spectator's task is to try to psychically pick the King that will be the perfect mate for the Queen. You remove the top card of the deck, and the spectator picks ANY King—he has a completely free choice of card. Despite the conditions, the two cards prove to be the King and Queen of Clubs!
This is successfully repeated with the remaining three Kings, with one final surprise. The final King is placed face-up on the deck, and the matching Queen magically appears below him. Finally, you turn over this King revealing the name "CASANOVA" printed on his back!
This is based on a Derek Dingle premise that appeared in Pallbearer's Review.
You require 4 double-backed cards to match your deck.
Remove the Kings and Queens—write the name CASANOVA on the back of the King of Hearts—then arrange the eight cards as follows—reading from the top down (note the fourth pair is in reverse order): KC-QC-KD-QD-KS-QS-QH-KH.
Place these cards face down on top of the deck, then scatter the four double backers randomly throughout.
1. Say, "You will all have heard of the famous lover Casanova. Although he has the reputation as the worlds greatest lover, he did have rivals. Three, in fact, and they were so similar to the real Casanova that very often, it was hard to tell them apart. So I'll use the four Kings to represent all four lovers."
Hold the deck with the faces towards you and spread through, removing the four double-backers, placing each on the table in a row as you come to them. As you lay them out, say, "Although we know these are the Kings, I want to keep each Kings identity secret from you so no one knows where any one King is in the row."
2. Hold the deck face down in dealing grip. Explain once more that the cards represent Casanova and his three rivals, adding, "I will give you one piece of information only, and that is the King of Hearts is most probably the real Casanova for obvious reasons... its suit!"
Tell the audience that you will try to locate the four ladies of the deck—the Queens—using your sense of touch alone. As you say this, carry out the actions of a Double-Undercut, but do not transfer any cards. In other words, in this instance, the cut is completely false.
3. Now lift the top two cards at the inner end and push the double forward until it is sitting off the deck, held in place by your thumb. Ask the spectator to pick up any King and give it to you. Take this card and place it square on top of the double, then flip over all three cards onto the deck. This reveals the Queen of Clubs. Comment that you found the Queen of Clubs, then push it over, revealing the King of Clubs—the card the spectator apparently selected. Lay both cards on the table.
4. Say that you will try to cut to a second Queen. Here, you carry out a Double Undercut taking the top cards of the deck to the bottom. Now carry out Step 3 exactly as above.
5. Repeat Step 4 in its entirety once more.
6. At this point, there are three married pairs lying face up on the table. Only one King (double-backer) remains. It is obviously the King of Hearts. Point out that despite the freedom of choice the spectator had, Casanova has waited until last.
As you are talking, Double-Cut the top card to the bottom, then obtain a break below the top two cards. Pick up the final card and place it on top of the deck, then without pause, flip over all three cards above the break as one. Sure enough, it is the King of Hearts.
Say, "It seems that Casanova has a mind of his own, and in fact, the ladies are attracted to him."
Push over the King to reveal the face-up Queen below it. Lay both cards on the table as if the trick is over. Then say, "Actually, there should have been no confusion about which card was the real Casanova when the cards were lying face down because its quite obvious!"
Conclude by turning over the King of Hearts to reveal the name, adding, "I dont know how you missed it?!" The cards can be examined, and while that is happening, you have ample misdirection to steal away the four double-backers at the bottom of the deck. Removing the card case from your pocket creates a perfect opportunity to ditch the four fakes.
