How to make the Three Card Monte

Cut the Ace as shown...

...and tape it onto the Eight of Clubs.

Fold it back forming a flap.

Place the King behind the Ace-flap as shown.

Cover the rest of the King with the Eight of  Spades.

After the middle the card is removed, show you have only the two Eights left.  Simply slide the Eight of
Spades over until it covers the Ace-flap.
