Yea! It has the other two gwent decks. I have not even started the first dlc (I really burnt myself out on witcher so still not ready to play again) but I'll buy for those decks alone. And hopefully eventually get to the dlc.
hearts of stone was great and that was just the small expansion. i can't wait for new gwent cards, new armor sets, and of course to explore the whole new map of Toussaint. Not just a small area added to an existing map but a completely new region map.
you might be missing some cards though. these cards might have newer ones from the new cards introduced in the B&W expansion. for example, HoS added the Toad card which wasn't part of the base game so the Nilfgaard/NR decks might be updated.
By far the very best RPG I've ever played! That last DLC "Heart of Stone" had some really scary moments. Yes, I'm talking about "that" character. It would be awesome if he..it makes an appearance in "Blood and Wine". The Last of Us and The Witcher 3 are my favorite games in recent memory.
