The effect: what they see
You riffle through the deck, and every card is different. Your friend stops you anywhere and remembers a card. Moments later, every card in the deck has become their card.
What you need
- A Svengali deck, available from any magic shop
The method
How a Svengali deck works
Half the cards in a Svengali deck are ordinary and all different. The other half are all the same card, and each of those is trimmed very slightly shorter. The short cards alternate with the ordinary ones throughout the deck.
Because of that difference in length, the deck behaves differently depending on how you riffle it. One way, the audience sees all different cards. The other way, the short cards fall in step with their neighbors, and the card that shows is always the same one.
That one principle gives you three powers:
- Show that every card is different, even though half are duplicates.
- Force a card. However freely your friend says “stop,” they get the same card.
- Change the deck. At the end, show that every card has become theirs.
The handling
TODO(owner): The riffle handling, the force, and the final reveal go here, step by step, in your own words.
Performance & patter
Everyone’s uncle has seen a Svengali deck trick at some point, often performed as “Is this your card? Look, they’re all your card!” Make yours different by giving the change a reason.
Suggested patter: “Have you ever thought about one card so hard you started seeing it everywhere?”
Now the ending isn’t a gimmick, it’s what happens when someone concentrates too hard. That’s a story they’ll repeat.
Common mistakes
- Handing out the deck. Once it’s in their hands, the secret is over. Switch to a normal deck if they want to shuffle.
- Showing the faces too slowly. The deck is designed to be seen in a riffle, not studied card by card.
- Doing it for the same audience twice. The force always gives the same card.
