Fellowship looks like one of mine that I've experimented with, but with Sam as the RB. I like the idea of having Boromir fight so much too.
Do you have trouble getting Merry out? 4x in a 120+ card deck is still a small chance. You also might want to consider Minas Morgul Answers for some light condition removal so you don't rely on Buckland Homestead.
Honestly Merry falls into the "nice to have" category, not into "mandatory". I'm usually fine if I can simply get
Imladris as site 3. Everything that is required to get the party going is there from the getgo pretty much.
Surprisingly I use the direct synergies between shadow and freeps side less in this deck compared to my "Shards of Narsil Hospital" build despite it being 20 cards larger, so I'd say it's pretty #$&*@! consistent in this form.
The fact that it laughs at the face
Her Ladyship and
Dark Horseman in multiple ways makes this deck very resilient, and overpowering it with brute force is pretty #$&*@! hard, which makes me want to toss in a
Spirit of the White Tree, and maybe something to combat archery to cover the missing angles.
