I'm glad you liked the deck! I also considered using Lore Aragorn, and your modifications are good, but if you're running Lore I would at least add Daeron's Runes or Deep Knowledge, as card draw is what the deck lacks the most, especially if you take out Galadriel.

I'm not a special "fan" of Galadriel. Her ability is great, no doubt of it, but it could fail the shot, and when that happens you just spent 3 resources for just 3 WP which will left game at the end of the round.

I've just played 3 games with this list,(well, they are really 5, but in 2 of them, an angry mission deck finished me off very quickly), and I have not missed more card drawing.

With 3 Sneak attacks, either Gandalf or Sentry are great draw options. I've finished the 3 games with a lot of cards in hand. Anyway, daeron's runes may be an option, because multiple copies of unique cards tend to accumulate in my hand. I still have to do a lot of tests, but the deck is really fun to play.
