Natural Duplicates

The Situation

You want to perform a "Triple Card at Number," but controlling three separate cards feels like a nightmare. You're worried about fumbling the deck or losing track of your breaks while managing three different spectators.

Using Psychology to Simplify Your Magic

Eloy Fernández explains a concept he calls "Natural Duplicates." This isn't about using a trick deck or complicated gimmicks. Instead, you use cards that look nearly identical—like the Seven of Hearts and the Seven of Diamonds—to exploit the gaps in an audience's memory.

By understanding how people perceive and remember cards, you can perform complex effects with much less effort. Eloy shows how you can use one single card to satisfy three different spectators, making your magic look cleaner and your sleight of hand almost non-existent. You'll learn how to build routines where the "twins" in the deck do the heavy lifting for you.
