I just did the Hobbit challenge. I decided to do Nightmare Conflict at the Carrock since I own it, but hadn't played it yet.
10 Rounds, 38 Threat, 19 Victory Points for a total score of 119.
I wanted to do something a little different from the classic so I went with Merry (T) / Pippin (L) / Bilbo and an army of Ents. The card draw with this deck was crazy! It took a while to get going, but by carefully underquesting I was able to play enough Ents to be able to take out each troll one by one.
Full decklist (and strategy) here.
This is the first time I've tried a full-out Ent deck, it was really fun! Definitely wouldn't work in quests that hit hard from the get-go though.
