Synergy

Yes, another instant download from Penguin magic. To begin the trick, the spectator can shuffle the deck as much as they want. After it is shuffled, the deck is cut into two parts. The spectator then selects one of the halves, and then from that half cards are taken from the top. One-by-one a card is seen, and all the viewer needs to remember is the card and position. They select whichever card they want. Then from the other half a different card is selected, but could be similar. This card is placed in the magicians pocket. The position of the card is given, and the magician deals down that many cards. The card is then given, and the card is no longer that card. But, now the card is found in the magician's pocket.

Great effect, let's step through it.

Pros:
Completely impromptu.
Easy
Great spectator interaction
has jaw dropping reactions

Cons:
minimal sleight of hand that requires one to be careful of angles

With this trick, the pros definitely out weigh the cons. Just practice the trick, learn the angles, and you'll have fun with this one for sure. The price is low, and definitely worth it. I would suggest practicing this one in front of a mirror. Before you know it, you'll see the angles that you need to be careful of, and have full confidence pulling this one off. For some, this is a home run effect and people freak out.
