This is mainly a thematic deck. Focused on the Tale of Tinúviel, and the story it tells, very similar to the story of Aragorn and Arwen.
The third hero I choose was Galadriel, because of her great ability which helps us to keep our threat low while she draws a card per turn (and also, she is Arwen's grandmother !)
All allies are Noldors, or Dúnedain (except Gandalf, which is great in the deck). Rangers of Cardolan helps us to defend against unexpected enemies / additional attacks, while the minstrels are there to find tales faster.
Combat is managed by Aragorn and a Tale of Tinúviel (Defend with Aragorn, play a tale to ready it and defend by 5/6, and then counter-attack of 6/7), if Gandalf is in play... it is even easier.
The deck is very fun to play, and also I think it is quite powerful while it is totally thematic.
Oh, I made a mistake when I said that all allies were Dunedain all noldor. Warden isn't (but I believe it's the only healing option worthy which is not a "one shot card"...), also galadriel's handmaiden, which are Silvan but anyway... they are related to Galadriel, so they can count like if they were ;P
