I actually prefer the new name(s) much more than the older 'Faction' and definitely more than 'Fanatics'. I like both Royal Lines and Lineage as names.
Next, I don't have a problem with the Jokers as others do, just thought I'd throw out my opinion.
My only comment regarding the tuck is that the front might be a liiittle too fancy for its own good.
That is, the lower part appears a lot fancier than the remainder of the art in the deck but more importantly a lot fancier than the black on white text right in the center of it.
Lastly, just wanted to toss out an idea in case you fancied it: The front could have a white background and a large royal crest made up of all 4 styles associated with the 4 suits, but each style makes up 1 quadrant of the crest. That way if you keep the black on white 'Royal Lines', it can sit above or below the crest and not look out of place.
Anyway love the direction it's going, keep up the good work!
