First, have the spectator shuffle the deck thoroughly. Then, have them select a card at random and sign its face. Return the signed card to the deck and place the deck on the table. Then... The deck silently begins to move and separates into two piles. When you check the card at the split, it is indeed the signed card. Finally, hand the deck to the spectator and have them confirm everything. The product includes two DVDs and a gimmick.
