"Window Swap" is a visual effect where a spectator chooses a card and signs it. Then, the signed card is returned to the deck. Next, the magician chooses a random card, different from the card signed by the spectator. Then, the magician uses a special card with a window. He places it over the random card and, with a snap of his fingers, it transforms into the signed card!


It will impress the spectator! And they can check both the signed card and the special card afterward.
