Note: Galadriel's Handmaiden is a proxy for Woodland Courier, a Scout that will be released in The Drowned Ruins.
This is a fun take on a "Scout" deck. Other than Galadriel (who cannot quest), the only non-Scout in the deck is Arwen. She provides much-needed resource generation and can safely quest on turns when you are not playing Scouting Party. As a backup, she can become a Protector of Lórien and be your defender, but the idea is to keep your threat low with Galadriel.
When he's not questing, Haldir helps to snipe enemies in the staging area. This deck dedicates itself to questing and location control, so it is best paired with a combat deck to handle enemies. With that in mind, another deck that includes Tactics with Rivendell Blade and Bow of the Galadhrim can help to maximize Haldir's ability. I skipped on readying of any form because the deck is a pure questing deck, so action advantage is secondary. For those who want to make it a bit more balanced, feel free to pull out some allies for copies of Unexpected Courage and/or Light of Valinor. It was refreshing to build a heavy Spirit deck without either of those two staples.
In any case, the location control here should be off the charts, and on turns when you are playing Scouting Party you can easily quest for ridiculous levels of willpower. Scouting Party and Sailor of Lune are just one example of the kind of fun combinations this archetype provides, but there are many more interesting interactions to be discovered. I look forward to feedback and seeing other players' takes on this new style of deck.
Can the Scout archetype actually make Lórien Guide playable, which not even her Silvan trait seemed to do? This deck seems like a good attempt at finding out!
