I had not seen their edition of Last Call, but that one looks acceptable.
I suppose your point about things being flush is in line with my own views. To me, having something jutting out of the book is more of a distraction than a feature.
Not that I would be reading the Lettered Regulators if I owned it, but I like to have the option to comfortably read it regardless! ;-)
The tarot card and poker chips are thin enough that I imagine they can be imbedded in the cover without being detrimental to reading the book.
