You show that your 'pet deck' has the ability to READ A SPECTATOR'S MIND!  A spectator thinks of a card. The pack informs him that it is not ready, and then informs him when it is ready.  Cards are dealt face up for another selection and a card appears which tells you to have the card selected face down.  Instead of telling the spectator the selected card, it asks for a hint.  You show a blank card and place it in top of the deck, telling the deck to tell the selected card or it will be recycled.  The card is turned over and written on the blank card is now the name of the selected card.  A weird plot!
