Heart Catcher by JT

Heart Catcher is a very visual location effect. A spectator selects a card, sign his name on it, then the card is shuffled back into the deck. The magician draws a heart on the back of the top card, then the heart disappears very visually. Finally, the heart goes onto the back of the selected card.

Advantages:

Very visual but super practical.
Easy to do, no sleight of hand needed.
