From the mind of Tony Ho - A visual card change effect.
Your spectator selects any card from a normal deck, signs their name on the card and puts it in the middle of the deck. You shuffle and take a card out from the deck, it's not spectator's card. You fold and hold it on your hand. With a shake of the hand, the card visually changes to the spectator's signed card.
