Game notes:

I guess I was pretty lucky with my cards. I didn't have to face any of the cave-trolls. In game 1 I had two goblin scouts in the first turn but I never got the chance to engage them.
In game 2 I got two dwarf allies out in turn 1, and the rest was just a walk in the park.

(I played a fourth game just to see if I could beat my score, but I ended up with 84. Not so much luck with my player cards (no Gandalf) and I had to face a lot of enemies, including the Cave Troll.)

Heroes: Aragorn (Lore), Theodred, Glorfindel (Spirit)
