Hello,
I own the basic game, Lair of the Wyrm, a hero and monster collection (Visions of Dawn), and now i bought Labyrinth of Ruin and Heirs of Blood. As i see at the Shop Item Cards of Labyrinth of Ruin, I think that is better than them in the basic game and the fisrt expansion (LotW). I have not read the campaign of LoR yet. I think that as the game progresses through expansions, the heroes have more options to get better and have precedence over OL. And I don't think that the new deck will help him.
