The all-time popular Svengali deck allows you to have a spectator select a card that will magically jump on top even when you bury it in the middle of the deck. The double svengali works on the same principle but each card is trimmed on the short AND long sides.
 
If you decide you want an ALTERNATE double svengali, the duplicate cards are going to be trimmed on the short sides and the regular cards are going to be trimmed on the ong sides. This will allow you to change the cards dribbled down by only moving your thumb's position. you won't need to  reverse the deck for your displays.

Our deck is of higher quality as the corners are rounded unlike the decks that are produced in big quantities from other companies.
