Effect: Spectator freely cuts off some cards from the top of the deck and looks at the top card of the bottom part of the deck. The cards they cut off are counted. Let’s say there are nineteen cards. Now the spectator cuts the bottom portion of the deck, thus losing their card. The nineteen counted cards are replaced back on top of the bottom portion of the deck.
Now with no moves whatsoever, the cards are counted off the deck again, one card at a time, until nineteen cards have been counted. Amazingly, the spectators chosen card is found at the nineteenth position, and it is face up to boot!
No duplicate cards used. A 52 card deck is used, and it may be used to do your other magic miracles as well. This is a killer effect that can be done at once. Can be repeated repeated.
