"Muster the Rohirrim. Assemble the army at Dunharrow. As many men as can be found. You have two days. On the third, we ride for Gondor... and war." -Theoden
This fellowship were made to focus on Elfhelm and his mounts. Idea was to build deck that could stack up heroes with mounts and songs but challenge was too big for one deck. This fellowship was created to get most out from Elfhelm and sphere fixing. To get some real value out from this idea I needed to add any version of Aragorn and his artifacts (Why not?) and Théoden.
Whole concept started to evolve into two decks. I needed mounts, songs, Théoden and some Aragorn with Sword that was Broken for more stat boosts! Concept deck seemed fragile and crowded but when split into two different decks with their own roles it could work. Some more thinking and pulling cards out from binders and fellowship was created.
This fellowship is obviously very janky but working. I played this fellowship two handed defeting Stone of Erech and Passage Through Mirkwood on nightmare mode. Both were rough but this deck managed to pull some wins (more losses). Some card justifications can be found on the description of each individual deck.
Why you should play this fellowship? You like jank. You want Aragorn with his toys. Or you want Elfhelm with mounts and songs.
