There are loads of resources out there for aspiring cardists to learn moves and flourishes. But what if the deck itself could help hone your skills? That’s the premise behind the Technique Playing Cards. With this clever deck, designed by Chris Severson, the colors aren’t just for show.

The different colors on the card backs represent different possible contact points, and the color placement varies across all 52 cards. “Each time you break off a new packet, you reveal a new back design and also a new location for your chosen color,” Severson explains in the description of the deck. By only connecting at one color point, the cardist is put into new positions and can create new movements with the deck.

Technique Playing Cards spent two years in the making, and have been on the market for a few months. The deck is available from many magic purveyors. (We noticed them thanks to this Instagram post from Art of Play.) Anybody already own some? Let us know if you’re having any luck improving your flourishes.
