First, the spectators' calls stop at any time during the magic card picking and signs the selected cards to ensure they are not stolen and no second identical card! Then the spectator puts away the cards and does not do any card control tricks!
Next, the magician pulls out a pen and sketches a heart on the back of the top card. With a shake of the card, the drawn heart begins to vanish bit by bit! The audience watches in amazement as the image of the heart fades away completely.
Opening the whole card again, I found that there was a heart painted on the back of one card. The missing heart found the spectator's card!
The card with the heart at the end can give the audience a memory, a perfect magic trick!
