The Derren Brown deck. It’s not only a beautifully designed deck of cards, with the elegant imitation of a leather bound artisan book, but it’s also the deck of playing cards that got me more into, well, playing cards! Since then it’s been a phenomenal experience to be part of this incredible community (albeit from a voyeurs point of view most of the time) and I thoroughly look forward to what is to come in the future from Theory11.
Good luck everybody.
