It makes a certain amount of sense with Keyforge, because the idea there is that you will buy multiple copies, or multiple decks. The price point of a single unit of Keyforge is very low.
This is a $60 game. Am I supposed to buy more than one copy? What value is there in it being "randomized" if I only need one copy to play, and I'm not likely to buy another copy?
I guess either I'm missing something, or "unique" is just a gimmick FFG is trying out.
