The four 10's are removed from a regular deck and clearly shown, then placed Face-Up to the side.
A card is selected from the same deck and returned back to the center. The four 10's are spread and one 10 is now Face-Down it is the 10H.
This tells me you selected a heart� for the first time they name their card. Lets say it�s the 3H. The entire deck is spread Face-Up, only one card is Face-Down in the center. The spectator looks at all the other cards THERE IS NO 3 of Hearts.
Now for the killer ending. The card in the deck is flipped face up, it is the 10 of HEARTS.The face down card in between the 10's is turned face up it is the 3 OF HEARTS.
