I like it, but it is admittedly tenuous. You could add the
ally
Shoulder to Shoulder design to keep Grimir nice and healed, but then the deck is getting bigger than it is likely intended.
Since
Narsil, Blade of the Faithful is not in the current deck list, I will remind you of a little trick: Use
Narsil, Blade of the Faithful on
Denethor, Lord of Minas Tirith for an extra draw. If you need to clear out threats or just want to ditch a companion, transfer the artifact to
Isildur, Bearer of Heirlooms (or another choice companion).
I would ditch the Gondorian Swords, by the way. If your deck is working, you are dumping your opponent's best minions. Those three extra card slots could be more copies of Gimli or Grimir. Or more importantly, perhaps more companions. You only have seven now, and the full strength of
Drawing His Eye is in a loaded
fellowship.
Derufin is helpful for obvious reasons.
Imrahil or
Dervorin are fine choices as well.
Finally, with no accounting for deck size (or how you will manage all of these Grimir exertions), don't forget that you can recycle your events with
Preparations/Rest By Blind Night.
Last Throw is an option for increasing the move limit, but with such a big Shadow hand...that might not be viable. I think most free peoples will just try to outrun you.
Best,
