Here is a miracle beyond words! 

You take the deck of cards out of the box, throw the card box up in the air to show it is empty and then close it up and put it down on the table. You then spread the cards and present the 'poRtal' card, which is then placed on top of the card box. Then a card is selected by either you or the spectator. It is then thrown towards the 'poRtal' card on top of the card box, and the selected card vanishes. You then open up the card box, and inside is the spectator's selected card.
