This is a thematic deck (yes, really!) designed to tackle the first two scenarios of the core set in conjunction with a Rossiel victory display deck for my narrative campaign, Agents of the White Council.
Eleanor will provide treachery coverage and be a competent defender, after we outfit her with a Gondorian Shield. Lanwyn will quest and, with Unexpected Courage, be ready to attack enemies. Thalin will soften up enemies in the staging area. Between him, Argalad in the other deck, and the Gondorian Spearman, enemies with up to 3 hit points can be destroyed without ever making an attack.
The questing allies will make up for the lack of starting willpower on the heroes, while the allies provide defensive coverage.
The sideboard includes cards for Journey Along the Anduin - Ride Them Down will replace A Test of Will, while Double Back will be added in without replacing anything.
Discussion of how the deck was put together, along with the theme it is following, can be found in my blog post here:

Should note that Defender of the West is a proxy for the upcoming unreleased card Necklace of Girion.
