That's looking nice! I would suggest that 42 (or there abouts: it's late) is very big. Maybe cut out some of the conditions? You're quite vulnerable to
Saruman's Power as it stands. Personally, I don't like vitality boosters all that much, as if you require them, you're only a condition discard away from losing the companion. I guess it's not such an issue with Elrond. If you are planning on shooting everything down, you could possibly even jettison
Gwemegil: just have Aragorn do the fighting.
Despite suggesting you take out some cards, one important thing I forgot was
No Stranger to the Shadows. If you deny the opponent Twilight, they can't play many minions for you to shoot down.
Also, you do have space for another companion. I'd suggest either Boromir and his Horn is an effective archer (with Rumil or my almost namesake), or Haldir if that's adding too many cards (as he can bear a bow)
