Do As You Want by Michael O'Brien

Effect: The magician removes two decks from his pocket, one red and one blue. The spectator gets to chose who uses which deck. The Magician and spectator then each chose a card from their respective deck and incredibly both cards match.

An extremely direct handling of the classic "Do as I do" plot. The spectator can see which card they choose and can even change their mind and choose a different card if they like. No forcing, fishing, or guessing required. Can be repeated and resets instantly!
