(The picture up here is what the magic should look afterwards)
Fan out the cards like so, EXCEPT, flip the bottom card like in the example that is below the picture on top.

However, hide the flipped card from the audience. That flipped card is the main part of the trick.

.2 let them pick any card from the fan, but make sure they don’t see the bottom card.

.3 while they examine the card they picked, you fold the fan and flip the deck over casually.
