Linking heart by Zoen's

Imagine a card is chosen and signed and the magician draws a hear on the back of the card.
then the magician draws another heart on a random card and strangely with a little shake, the heart dances across the back of the card.
The heart then vanishes and strangely when we look for the spectator's card in the deck, the heart appears linked to the other heart on back of the spectator's card.
