Think Nguyen - Triumph Under The Table

A participant selects a card from one half of the deck, which is then returned to the centre of that half. The deck is fairly shuffled, with one half face-up and the other face-down. A second spectator takes the deck under the table and mixes it further before handing it back to the performer, still out of sight. The performer claims they will turn all the face-up cards face-down without looking. When the deck is spread on the table, all the cards are indeed face-down, except for the selected card, which is face-up! As a final surprise, the performer asks for the spectator’s name. When the deck is spread again, a four-of-a-kind that matches the number of letters in their name is revealed, face-up, scattered throughout the deck.
