The spectator selects a card (e.g. Jack of Clubs), and is lost in the deck. The spectator may even shuffle the deck. The magician takes the deck back and takes out 4 cards that he believes will help him determine what the selection is. All four cards happen to be the selection, the Jack of Clubs!
But, the magician feels sorry for the Jack of Clubs that he is all alone, and so with a tap of the deck, he summons the three other Jacks to be with the other Jack of Clubs.
Now that the four Jacks are here, the magician will now show their acrobatic abilities. Each Jack is placed face down on the table. The Jacks them proceed to jump all over the deck, and even jump into the deck from the magician's pocket!
