This is one of the 2 decks for Passage Of The Marshes in my Thematic Saga run (which includes the 2 PoD quests that are inserted after the 1st quest in Black Riders.) I beat the quest twice on Easy Mode with the Fellowship.
Boons: Sting is in this deck.
Most important thing you want to see in the opening hand is Armored Destrier to put on Beregond in the other deck. Shadow effects can really kill you by a thousand cuts in this quest --- and the Mount really helps with this.
Visionary Leadership and Gondorian Shield are a close 2nd place for cards you want to see early. (The Shield is also for Beregond.) I tend to put Visionary Leadership and Steward of Gondor on Faramir
The trickiest part of this deck is timing when to kill the enemy that has Secret Vigil attached. This enemy needs to die last otherwise the threat reduction won't happen for at least one of the decks --- due to all of the Undead preventing threat reduction.
