It is a hands off impossible card divination that can be done with any regular deck and no gimmicks.
Either you or your spectator shuffles the cards. While your back is turned they cut to a card, they memorize it, and they bury it somewhere in the deck. You turn your back around, and with 100% accuracy, you can go through the cards and remove their thought of card.
To perform this effect, you will need a very small setup that takes only a few seconds.
