At the time of building this deck, my collection only consists of all cycles through the end of the Ring-Maker cycle and all released Saga expansions. And one random Treachery of Rhudaur AP because it was on sale.
This deck was built as a potential deck to use at Gen Con 2016 against The Siege of Annuminas. That is part of the reason why the sideboard is rather large.
Basic Strategy:
Get out Vilya and readying effects on Elrond so that he can quest/defend and then use Vilya as often and early as possible. You will eventually build up a board state of giant allies that can handle questing, combat, healing, card draw, and resource generation without any trouble. The hero selection and use of Elrond's Counsel is intended to keep threat relatively low so that enemies aren't forced to engage until your board state is secure. The final state should include Elrond able to defend with 4 defense and sentinel (Arwen's bonus), built-in shadow cancellation (A Burning Brand), healing (Warden of Healing and/or Lembas), readying (Lembas and/or Unexpected Courage) then dropping another big ally or important attachment with Vilya. Using Master of the Forge, Zigil Miner, and Vilya nearly every turn will eventually go through your entire deck. At this point, using Beorn's attack bonus which shuffles him into the deck allows you to move him back to the top with Imladris Stargazer and Vilya him into play again for potentially a second attack in the same round. Gildor sets up Vilya or Zigil Miner for turning duplicates into resources or getting big allies into play for free.
Other card options:
-Frodo Baggins or Pippin for Glorfindel/Mirlonde - quest/group dependent.
