Torner by Maulanas

There is a string hanging from your card box with a piece of tape stuck to it with the writing "Your Card" on it. The spectator picks a card and places it back in the deck.

The piece of tape that says your card instantly changes into the corner of the chosen card. When you find the chosen card in the deck a corner is missing.
