Yeah it would be nice if they shed some light, but clearly it's flying off the shelves like hot nuggets (pun intended) and they may not really care to elaborate since it may have not to benefit?
I think its a cool branding play on a historical deck, I have no credentials to weigh in on the legality, I'm just commenting as a collector. I am guessing if Hason Chien Production Co are putting themselves out there with this they have done some research? since this is created and produced by them. Regardless It just makes you smile to look at the court cards 😄
