ACAAN Carta al numero by Gianluigi Sordellini

From a deck of cards, the spectator selects a card and then loses it in the deck without showing it to anyone. The performer takes another deck of cards, shuffles it, and shows that each card is in a random position. He notices two twin cards in the center. Taking advantage of this, he says it's a sign of fate and that he will use the twin cards to find the selected card, even though he doesn't know what it is. He shuffles the deck again, and magically, the pair of twin cards capture a card, which turns out to be the twin of the chosen one. Undeterred, the performer adds the value of the twin cards plus the captured card, and by counting down from the top of the deck to the resulting number, he arrives at the card selected by the spectator.
