I think you'll like this a lot. Four aces and four kings are shown. The kings are palced faced down in front of your spectator.
Now one by one the aces in your hands change to become the kings (this knock thier socks off). As you point to the cards on the table you ask where they think the aces are?
As your spectators turn over the cards they belive to be the aces the see the four kings & you are left still holding the aces!
This effect is great, we completly sold out at this years Top Secret Magic Day in Milton Keynes!
