You will show the prediction of the playing card on the card box and tell the spectator that he will choose this card. After the spectator really chooses the card you predicted, you will ask him if he understood how the whole illusion works. Whatever the spectator says. You will smile and reveal that none of this actually happened. You will show that all the cards in the deck are blank. Spectator's card is now also blank and no prediction is written on the box.
This trick doesn't use any complicated manipulations, you don't have to steal anything away and you can create your own gimmick in less than five minutes from things you may already have at home.
This is Fata Morgana.
