A spectator selects a card, which is then lost in the deck. You snap your fingers, and their card rises straight to the top!

A classic Ambitious Card effect, you might say! But just wait until you see what happens next...

The card is placed back into the middle of the deck.

Show the top card. Of course, it's not the selected card! Now fold the corner of this card and place it face up on top of the deck, right in front of your spectators. VISUALLY, THE CORNER CHANGES!

Pick up the card again, and yes, this time it really is the spectator's selected card!

Self-working - Visual - Original

A clean gimmick with an impossible finale!
