Glad you changed your ring for
ATAR!
For the Fellowship side i would say for you to drop some extra companions and get more copies of the essential ones! Cut out
Turgon (start with
ingold instead) and Faramir and put more copies of Aragorn and/or GoG. Also drop the
First Level and add one more
Sapling of The White Tree. Since
don´t have much condition removal you can consider to put some
Athelas to get rid of annoying conditions on your companions and/or get a healing when needed. Your Isildur will die badly to corruptions decks, maybe
Scroll of Isildur can help you with that.
For the Shadows maybe cut Suzerain and one copy of Chiefitain for two Desert Lords. this way when you get the initiative you can aim exertions in the companions to improve your killing capacity with the assing-initiative-wound characters... Or you can consider Souhtron Veterans for some crowd control, cause big fellowships (like ents) can cause some trouble to your shadows, and they are ambush... But if you think Suzerain is working good i guess you can keep it.
