Learn an original card trick where you can cut to all four aces (or any four of a kind). Lose any four of a kind in a standard unmodified deck then demonstrate skill by re-locating them by touch!
Totally impromptu! Use any deck!
When finding the Aces you can ask your spectator to say “Stop” at any point. Instead of Dribbling the cards every time, you can try Small Cuts, a corner riffle and even deal cards one at a time.
