Note that for many of the routines already mentioned, one can change the presentation in order to spell to the name of the card, not just count to a random, arbitrary number. The magician takes the deck and names any random card, and spells it out, one card per letter off the top of the deck, and ends on an indifferent card. The deck is then handed to the spectator, who is asked to spell to their own card (which is "unknown" to the magician). They do, and the last card used to spell their card is turned over, and it is their card!
