A trick deck is a deck of playing cards that has been altered in some way to allow magicians to perform certain card tricks where sleight of hand would be too difficult or impractical. Trick decks Stripper deck A stripper deck (also known as a tapered deck, wizard deck, or biseauté deck) allows the magician to control the main location of a card or group of cards easily within the pack. Even after being shuffled into the deck by a spectator, the magician can cut to a selected card. Similarly, even after being lost in different parts of the deck, the magician can move multiple cards to specific locations using basic shuffles. Unlike the invisible or svengali deck, the stripper deck can be handled by an audience member unfamiliar with the concept and can withstand a modest amount of scrutiny without exposing the secret; however, this deck is found in a number of beginners' magic kits, so the secret is well-known, even among non-magicians. The cards of a stripper deck are slightly tapered, so that the sides no longer form a perfect rectangle. The change is slight enough to be undetected by visual inspection or even casual handling, but if a single card is rotated 180° so that it's tapered in the opposite direction from the rest of the deck, the card's broad end can easily be detected, by feel or even by sight, among the narrow ends of the rest of the deck. At this point the magician can select the target card through sleight of hand. Many of the effects achieved with a stripper deck can also be accomplished with sleight of hand. Svengali deck The deck alternates between normal cards and shortened cards, with the shortened cards all of the same rank and suit. When the deck is riffled front to back, only the normal cards are visible; when it is riffled back to front, only the shortened cards are visible. It was created by Burling Hull and marketed by WD LeRoy in 1909. The deck can be dribbled or riffled to create the illusion that the deck is completely ordinary. It can even be shuffled. One basic trick involves a spectator choosing a card from the deck and returning it; the card can then appear practically anywhere in the deck, making tricks like the Ambitious card incredibly simple. The final and most stunning trick is when
