Two Decks to Rule Some of Them
These two decks are built using the first two cycles and both Hobbit Boxes, i.e. every release before Heirs of Numenor. They are designed to work in tandem and beat all quests released in that period, minus the Battle of Laketown, which I do not have yet. I have no idea how they would fare against it.
The central combo is Support of the Eagles/Boromir/Song of Earendil/Aragorn/Desperate Alliance and kind of Arwen. Boromir with Support of the Eagles lets him attack or defend multiple times with a huge buff, and Song of Earendil and Desperate Alliance/Aragorn plus lots of threat reduction let him do it over and over again. Arwen provides Boromir with sentinel in case he has to cover for the questing deck, but most of the time Boromir will optionally engage every enemy that comes off of the encounter deck. There are very few enemies who can scare these decks.
If you're looking for a pair of pretty powerful decks that still involve lots of decisions than these should do the trick.
Changes I've made in the past few days: -1 Miruvor, -1 Escort from Edoras, -1 Miner of the Iron Hills, +2 Arwen Undomiel, +1 Asfaloth.
