theory11 Playing Cards
theory11 is possibly the biggest and most mainstream playing card-producing company. Its signature style connects all of its decks. Its luxurious tuck boxes, heavily decorated with foil and embossing, have become the trademark of all theory11 decks.
They became popular outside the magic community thanks to their collaborations with franchises like Star Wars, Marvel, Star Trek, and Harry Potter. They also created decks dedicated to famous musicians, including Elvis Presley, The Beatles, and The Rolling Stones.
