Ultimate Free Choice by Alexander Hermann

"Ultimate Free Choice" by Alexander Hermann (the living German one, not the French one that died in 1896) is a deceptively simple routine with a punchy and surprising ending that will leave them stunned.
After informing your audience that you have a prediction in your pocket, you spread the deck face down and invite someone to participate in what could be best described as an "anti-card trick." Instead of selecting a card they want to keep, they choose a card they wouldn' pick. This process is repeated several times, with the participant eliminating a portion of the deck each time.
Ultimately, only one card remains. With empty hands, you then reach into your pocket and reveal the prediction card. It perfectly matches their selection.
Yet nobody reacts the way you expected. It seems they all noticed that you had extra cards in your pocket.
This is true. You did have extra cards. But, as a surprising twist they'll never see coming, you reveal that all of these cards match too.
