A fine start! This looks way better than the decks I first made, haha. Depending on what ends up giving you trouble there are a few different ways to alter it without changing the heart of it, which is a great place for a draft deck to be. I just have a few things to consider up front:
What happens if you don't go first? You only have two cards that depend on Aragorn, but if you plan on using his healing to get you out of some tough spots then you might consider extra copies. Not only will this bring him in earlier if you can't start at Prancing Pony, but you'll have some healing for him tucked away. You decide if this matters to you.
I think
Armor would go a long way against Uruk-hai and The Balrog, especially with your Boromir/Aragorn setup. Your deck is also a perfect candidate for
Sleep, Caradhras, which is perhaps Gandalf's greatest strength. What is it you aim to play (or avoid seeing) with
Pathfinder?
No Stranger to the Shadows is an all-around good card, but with this setup I wonder if that might be a place to cut. Choke is best early in the game, so while it
always helps to give your opponent
or
fewer, later on (generally when you'll draw it) it won't be as critical as some other cards.
Betrayal of Isengard is situational so many people don't use it in favor of something more consistent, but it's saved me a few times so I'll throw that out there.
For the Shadow side,
Saruman's Power would be great against
The Last Alliance of Elves and Men decks. It's often worth losing your own
Saruman's Ambition to take Aragorn and Boromir down 3 strength. And, just as I suggested
Armor for your FP, I'll suggest
Beyond the Height of Men for your Uruks
You've got the pumps to win skirmishes, so make sure your opponent feels it. Adding them might mean readjusting the amount of pumps so you have enough minions every turn. If you end up adding cards maybe include 1 or 2
Abandoning Reason for Madness? With a deck this small you could probably pass on it, though it never hurts.
