A guy a year below me was amazing at card tricks. My favorite to see him do was the Stigmata, where he would like rip up the card or do something to get rid of it, but he'd rub his arm and the number of your card would appear in red (like the skin had been magically irritated in the shape of the number).

His crowd control ability was aces too; lots of jerks who didn't appreciate the mystery of his performing art would be like "I WANNA SEE THAT AGAIN" "HOW DO YOU DO IT" and he could fend them off without even blinking. Pretty cool guy tbh.
