Here's a deck idea I've had using Idraen and Lorefindel. It's nothing to crazy, Mirlonde is my 3rd giving me a lower starting threat with (29). Idraen gives Glorfindel LoV, and he breaks locations with Asfolath. Lots of Lore card draw and Spirit threat reduction. Once the action advantage is set up and you have Treebeard or Wandering Ents out for defenders, Idraen and Glorfy attacking together squashes most enemies. I dont try to engage to often, I think this deck is more about sneaking past enemies than pulling everyone you can for combat. There's somethings I'll drop/add/change once I get my copy of the Steward's Fear. I try not to build decks with cards I don't physically own. I'll open to advice, I look forward to it really.

Ringsdb link is apparently easier to read than the text list
