A Right Mess
A spectator cuts the cards into three piles, looks at the top card of one, then mixes the cards, some face-up, some face down. The deck is then shuffled. The magician is still able to find the card.
A self-working trick, but you’ll need to be able to perform a riffle shuffle. Fortunately, I teach you that too!
