We all know the classic part of an effect where the magician takes a card out of his deck and uses it as their card or as a "detective" to try and find the spectator's card. Generally, we as magicians ask "That's not your card, correct?". Another classic tactic used is the "I messed up" tactic, where we pretend to mess up. What if we were to mix the two? Do you guys think it would work if you ended up using the spectator's chosen card as the "detective", and making a routine out of it?
