This is a thematic Silvan deck, organized around the theme of the Woodland Realm, rather than Lorien, designed to face the first two quests of the core cycle as part of my narrative campaign series, Agents of the White Council.
This deck is primarily oriented around supporting the questing deck with staging area damage (via Argalad, Galadhon Archers, and Hands Upon the Bow), card draw, healing, and victory display shenanigans.
Rossiel is intended to be built up as the deck's primary defender, with Sentinel via Elven Mail to defend for the other deck too. A Burning Brand, Cloak of Lórien, Protector of Lórien, and Gondorian Shield from the other deck will all help boost her effectiveness in that role. Legolas with Bow of the Galadhrim helps kill things, and helps put progress on the active locations.
Discussion of how the deck was put together, and the theme it is built around, can be found in my blog post here:
