13 Card Mystery

The spectator grabs a single suit, orders it Ace to King, and spells a value of their own choosing to the bottom of their pack — all out of sight of the magician, so nothing is telegraphed. Two more silent spells layer on top, each spectator ending up somewhere different and unknown to the performer. Then a single number, called out at random, sends everyone counting down together — and the card that surfaces matches the value each of them started with. Alain Nu's 13 Card Mystery works whether it's one spectator or a room full of them — watch it and see the sync land.
