It's clear they aren't using USPC to print. They have way more than "30 years of experience."
This is really not a deck project so much as a game project. It's confusing about the different colored backs, and the inclusion of a fifth suit, Box, while at the same time only making 54 cards in the deck, valued 2 through Ace. Are some cards skipped? Are there more than one deck color to choose from?
Lots of unanswered questions. It also forces me to ask, "Why on Earth does this game need a custom deck?" To my eyes, playing with a standard deck and off-the-shelf colored dice would work just fine.
