I have to disagree. Well the first two cards like pretty kewl but the last ones are way too disney like to me. I hope they get back to the "raw" art style that the first cards has. Cards like WH riders, warriors and Eredin remain the coolest IMO.
Oh, I'm playing Blood and Wine for the first time and Touissant feels like separate faction
I remember something from the books, about the connection you mentioned, but I thought they wouldn't actually fight for Nilfgaards.
But yea, your point about Scoia leaders convinces me.
