The Collector's deck doesn't require sleight-of-hand, it's easy to do and is a real baffler. The effect starts with two cards you have pre-selected from a deck that has many different back designs. The spectator randomly selects two other cards from that deck. Remember, the spectator has a free choice of cards. Yet, the backs of his cards exactly match the backs of your two cards. That in itself would be a great effect, but, there's more. When the spectator turns his two cards over, he finds that the faces also match your cards. The spectator will obviously want to see the rest of the card deck. That's OK. Because, when he turns the rest of the cards face-up, he finds all the other cards have identical faces (different than the matching cards) and of a different color. WOW!

Comes complete with poker sized premium cards. 

This trick is also known as kaleidoscope cards.
