Pairing up the Noldor-Silvan power couple, Galadriel and Celeborn, this deck engages in Silvan shenanigans (allies entering and leaving play) while offering a fairly well-balanced solo experience.
On opening hand, you really want to put Nenya on Galadriel, either directly or by drawing Mirror of Galadriel. This allows quad-sphere use, particularly for The Tree People to pop allies into play (ideally, use The Tree People for allies like Haldir of Lórien for questing/attacking or Silvan Tracker for consistent healing).
The deck can be a slow starter because of its tri-sphere nature, but once you get the Silvan engine rolling, there should be few issues with questing (Celeborn gives +1 of all traits in the round allies enter, Galadriel gives entering allies questing without exhaustion, and Nenya gives +4 quest to one character).
Ideally, Legolas will be used primarily with attack with at least one Rivendell Blade, and can help with location/quest progress in destroying enemies. Defender of the Naith is a great blocker, but Celeborn comes in handy on initial rounds as well.
Do you use Defender of the Naith with Cloak of Lórien? I'm going to give this a shot, I've yet to play a Silvan deck.
