Emergency Card trick

A card is selected, and the magician attempts to read spectator's mind and fails. He removes an Emergency Card (EC) . This tells me that your card was the 2S. The EC is unfolded to show 2S. Wrong.

Then, your card must be the 5S. The EC is then unfolded to show the 5S. Wrong again. Was it a black card? No. I see. That means your card must be the 7H. EC is unfolded to show 7H. No! I'm positive you will see your card this time.

EC is unfolded to show all 52 cards. Do you see your card? You do! I knew it all the time. Which one was yours? The Two of Diamonds?

Emergency Card is unfolded to 8' x 11 ?? to show the 2D!

Sized to fit in hip pocket or the cellophane on a pack of cards, ready whenever you need it.
