I've been pretty pleased with this deck I've been playing. It breezed through the first and second scenario. The only downside on the second scenario is the starting threat of 30 means the Troll instantly engages. I used Protector Of Lorien so that Berevor could survive defending against the troll, then next turn I played a Forest Snare. A second Troll came along a few turns after, but luckily Gandalf was ready to deal him some damage.
There's lots of options in this deck - healing, card draw, threat reduction, card effect cancels. One downside is that the hugely useful Northern Tracker is expensive to play. Hopefully later on they'll be a card to give Spirit to other characters (other than Aragorn). I did consider Denethor over Berevor, but Henmarth Riversong can fill in for his excellent ability, and Berevor is an excellent all-rounder. She's even more useful with Unexpected Courage on her.
