Just posted this in the Acquisitions topic.
The sticker seal is very similar to that on the Gatorbacks - and probably a few other recent Blaine decks. The GBs have a silver seal, though, with an alteration to the bottom and it also appears larger.
Yes, the faces are standard - of a sort. They're the old-school faces Expert/CARC put on most of their own decks, with the exceptions of the Jokers and Ace of Spades (as noted) AND that the courts are altered like most Blaine decks with images of his friends and family.
The coating is REMARKABLE - slicker than usual while not as slippery as USPC's Magic Finish. This is a good thing. Even a "specially-abled" fanner like myself can make a decent-looking fan out of them.
The box says "Special Edition of 2015", which one could look at two ways. One could guess that the deck will be released next year for the public (if 2015 is a year but not a quantity) or, as mentioned by the Microsoft intern below, it's an indication of the number of decks that were made, specifically chosen because that's the year Microsoft wants the interns to return - a reasonable assumption.
