An incredible coincidence effect performed under impossible conditions. You divide a deck in two and bind each portion so that it becomes a book of cards.

The spectator chooses a card from one book.

Dealing through the books simultaneously the chosen card falls at the exact same position as its mate. No other cards match.

Now for a miracle finale. Because now when the cards are leafed through, every single pair matches.

This despite the fact that the cards are still bound together. So clever you will baffle yourself!
