Mercury - David Kong/Ellusionest
You cleanly show 4 cards to the spectators to be the four aces. You close the spread and without a single move, you spread the cards again to reveal one of them has turned face down. You close them, and once again spread them to reveal that the second Ace has turned face down. You continue this until all 4 Aces have magically turned face down in your hands. Amazing? Thats only the beginning!
You then reveal that the four cards you are holding have been the 4 kings all along, and theres not an Ace in sight. But where did those Aces go? You got it! Into the middle of the deck that the spectator has been holding the entire time!
CONDITION: BN in case
