The Svengali Magic Deck allows you to do Magic Tricks that require absolutely no skill. While the deck is ridiculously easy to use, it is also the deck used by leading Magicians.With Svengali Decks, a spectator choose a card from what looks like a regular Bicycle Poker Playing Card Deck – no one will be able to tell the trick cards from regular ones. When the chosen card is returned to the deck, the entire deck changes to match the card!
