You and I by Rafael Benatar

You and I is a perfect commercial card trick. This deceptive method is funny, has tons of audience interaction and the effect seems completely impossible. This trick gets better and better after each revelation and then ends with a complete surprise. It is the perfect matching card effect.

Here's what happens:

You give half of your deck to the spectator and you both shuffle. You trade your halves and the top card will match; same color and same value, time and time again. It even happens when you trade cards with other spectators. All that AND an amazing surprise ending.

No gimmicks, no difficult moves, and nothing is added to the deck.
