I received a forward with a playing cards and david copperfield. How did it work?

There are six face cards in a row. It says to pick one card. Just look at it, don't touch it or put the mouse over it. Then when you scroll down it shows David Copperfields face and says to look into his eyes thinking of the card. Then scroll down again and your card will be gone from the six. Does anyone know how this works? It happens every time.

The cards that you see in the beginning are all changed. None of them stay the same, so it doesn't matter which one you pick.
Reply:Look closely at the cards. The six cards are different each time. None of the suits are the same. So no matter which card you pick, the exact card you chose will not be there!
