Mostly I'm just glad this card exists because it's frustrating to me that Sting, Glamdring, and Orcrist all got non-campaign releases but the Flame of the West (which is really a far more significant sword in the legendarium) never did.
As for its implementation, the trait requirement is obviously designed to go with the colorless Aragorn from the same set. I'm really not sure there is a use case for this card outside of a deck with that colorless Aragorn and a generous surplus of resources. So it's very limited, but given the sword's role in the story that does make sense. Theoretically, a lot of other people could have wielded Glamdring, Orcrist, Sting, etc. but Anduril was always tied to Isildur's heir alone.
My best success with it was in a leadership/tactics Gondor deck with Aragorn's starting title being Elessar (which makes Gondor even more amazing at defense than they already are). With Elessar, he is qualified from the get-go and you don't have to fish for more traits before he can wield Anduril, though the leadership resource icon is made redundant. Also, it's very convenient in a deck like that to give SoG and Chieftan of the North to Aragorn, and then with his multiple resource icons he can easily afford expensive cards. If anyone can come up with a better use case than that for Anduril I'd love to hear about it, but so far it seems far and away the best place for it to me.
