Well, as I don't even have the book yet, I'm not sure how much help i'm going to be. Ordering mine today either from here or the Warstore.
However, when i first heard about the card mechanic, i was worried about single deck card counting (being a poker player that's just good enough to be dangerous to myself, but not good enough to be dangerous to casinos ).
When the mechanic was explained in greater detail, it dawned on me that due to the suit trigger mechanics (and pardon me if i'm butchering literal names for things - again I != have book), "cheating", and other things made that a non-issue.
Mostly the fresh approach to wargaming sans dice is cool, and from what i've seen and had explained so far, a deck of cards won't ruin immersion in the setting, which is immediately one of the strongest things going for the game.
Still - been a long time since i was this psyched about a new game. Getting my first real game this weekend.
What i like too is that immediately, i'm drawn to several crews: particularly the neverborn and ortegas. The ruleset has that "non-homogenized, but small and tight" ruleset that i adore in games, where things are just as unique as they need to be without being cluttered and arcane.
Anywho... enough rattling. Looking forward to it. Oh, and the book is beautiful guys. Even a quick thumb through left me impressed.
