I use standard Bicycle 808 playing cards most of the time (I buy them by the dozen), but I love the Mystery Box playing cards created by Theory 11 (with input from amateur magician J.J. Abrams). The new “Black Edition” was just released. I won’t say much about them, other than the fact that they are gorgeous, because I don’t want to spoil any surprises. I will add that you should study the cards and box closely.
