GT Speedreader Marked Deck: Red Bicycle Mandolin Cards With a Readable Marking System


 The GT Speedreader Marked Deck Standard Version lets magicians identify a playing card from its back, opening possibilities for card revelations, predictions, and apparent mind reading.

This red-backed Bicycle 809 Mandolin edition, manufactured by the United States Playing Card Company, combines a familiar playing-card design with a marking system intended for quick recognition.

Designed for Straightforward Reading

According to the product description, GT Speedreader uses an intuitive system without unusual symbols, separate decoding charts, or mathematical calculations.

The markings are designed to be discreet within the back design and concealed during a conventional spread. As with any marked deck, visibility depends on the handling, viewing conditions, and how closely someone examines the cards.

The manufacturer notes that the layout is best suited to right-handed performers, an important consideration when choosing a deck for your preferred handling.

Possibilities for Your Card Magic

A marked deck provides information that can support many presentations. Knowing a card’s identity can become the starting point for a prediction, an apparent demonstration of intuition, or an unexpected revelation.

The GT Speedreader system does not require a particular stack or card order to identify individual cards. That gives performers flexibility when incorporating it into appropriate routines.

An Online Effect Is Included

The package includes online access to “The Trick That Can’t Be Explained” from the GT Speedreader DVD by Kozmomagic, providing an effect to explore alongside the deck.

Additional routines and instructional material are available separately.

What’s Included?

  • Red Bicycle 809 Mandolin-backed marked deck

  • Marking instruction card

  • Marked double-backer

  • Jokers

  • Poker-hand guide card

  • Online access to the included effect

For magicians interested in adding a marked deck to their working collection, GT Speedreader offers a familiar Bicycle appearance, a system designed for readability, and supporting instructional material.
