Well, there are several things that make the Freeps look a bit.. crappy. First the 4 Sams. Drop at least 2. Then
Elf-Song. You already have a 12 resistance Ring-Bearer and
Sam, Son of Hamfast, which seems waaay enough for me against corruption. Even though you have those Burden adding cards, just let Sam survive and eat 3 Burdens at a Sanctuary. You could also consider starting Sam and use several copies of
Greenleaf, as really has to exert often, so you can discard leftover copies for more healing.
Second, you only have 4 comps. Even though you play Choke, it's actually better to use 5 comps against Swarms, and that you get a bigger card pool to use. I agree that
Aragorn, RoTN is a very good idea.
An able guide is a great choke card for double-moves, as are
Bill the Pony (x-ed) and
gondor's vengeance. Ellesar Telcontar would also be quite useful as he a) has the Frodo signet and b) provides some healing. Aragron's Bow should solve most Swarm problems, you also neither have
BRC or any condition/ possesion removal. I know that it sounds scary, but as Movie format exists since 2004 (... 2004, right?) it has really been improved.
As for your Shadow... any good Freeps with sufficient condition removaland a high resistance RB can easily survive against this kind of Deck.
