A Svengali Deck is a trick deck of cards. Half of the cards are the same size as a regular deck of cards; the other half, however, are a touch shorter than standard size. 

These shorter cards all contain the same number and suit on them. This difference allows the user to manipulate the deck of cards without the need of perfecting the “sleight of hand” technique.

Hundreds of tricks are possible with this one deck of “magical” cards!
