The Jinx Prediction
The performer sets aside three prediction cards to return to later. The participant chooses four cards from the deck, and they are placed in a row on the table.
The participant is told that one of the cards they chose is special, and they are asked to use their intuition to choose which one it is. They have a completely free choice among their four cards, and they have the opportunity to change their mind as many times as they like.
Once they've settled on one card, they look at what it is and are surprised to see that it matches the three predictions the performer set aside at the beginning to form a perfect four of a kind.
What's even better is the three cards they didn't choose are ALL revealed to be blank.
The performer ends clean and everything can be examined.
