This is a self-working card effect using a special deck of cards with 52 different backs collected from 52 different Indian casinos.
 
Two cards are dealt face-up blackjack style. The two cards are split from each other, the remaining cards are dealt face-down in front of each of the two cards. When the helper tells the dealer to stop, the two face-up cards are placed on top of their respective pile. At this point it is shown that the cards were placed next to the only cards in the deck that matches the two cards.
 
This effect comes with an Instructional DVD, to help you perform this effect flawlessly.
