Tried this recently and found it effective... but figured I'd see if I'd done anything wrong.
Spirit/Lore Deck (Eleanor/Beravor/Glorfindel) - Main Idea is to use Northern Tracker to take out Rhosgobel during the first phase of the quest and post pone heading to stage 2 until you can rush it and have Wilyador healed.
Norther Tracker takes out Rhosgobel
Daughter of the Nimrodel, Lore of Imladris and Radagast heal Wilyador
Eleanor takes out treachery cards
Beravor draws cards
Hasty Stroke takes out Shadow Cards
The Galadhrim's Greeting keeps threat down
Dwarven Tomb Brings back Hasty Stroke or The Galadhrim's Greeting as needed.
Henemarth Riversong let's you know what's coming so you can manipulate how you deal with Phase 1
Haldir of Lorien and Gandalf Deal with annoying Enemies that can only be hit with Ranged or Eagles.
That's the gist... there is a leadership splash with Song of Kings, Rivendell Minstrel, Steward of Gondor and Sneak Attack.
Anyways... unlike Carrock which specifically says its immune to card effects Rhosgobel doesn't. This seems like an effective tactic. It tough though . You need to get a Northern tracker out quick and pick up some healing cause Wilyador will be in bad shape by the time you scout out Rhosgobel, but once Rhosgobel is out of the picture you can heal up Wilyador and prepare for your assault on Phase 2.
