This is a naval-themed deck for the Dreamchaser cycle. To make the player feel aboard a ship, it favors theme and fun over efficiency (for example, most allies are sailors). It has passed all the scenarios of the Dreamchaser cycle without a single change (cf. caveat at the end) in solo play.
Concept: The main encounter deck weakness that is exploited is the relatively high threat of the enemy ships. Galadriel alone almost gets rid of combat if you can keep your ship on-course. This allows the deck to focus on questing and location management. By the time you engage enemy ships, thanks to the insane card draw, you’ll probably be ready to blank them with Revealed in Wrath and avoid confronting any non-ship enemy.
Lots of drawing: The deck is probably the best drawing deck I have played. With 1 Silver Harp in play to keep Círdan the Shipwright’s additional card, it’s a minimum of 3 cards per turn, but add to that Mirror of Galadriel, Elven-light and Lindir, and that’s a lot of cards you’ll be going through. This means that you’ll see all the one-offs quite reliably. All of them have proven useful. For example, Mariner's Compass not only shuffles problem locations back into the encounter deck, but also helps with sailing tests, since the problem locations usually have the helm icon. Another important one-off is Song of Battle, to enable Revealed in Wrath.
Testing: Although it passed all the scenarios of the Dreamchaser cycle in solo play, it is clearly ill-suited for scenarios that force you to engage non-ship enemies in the first turn or so. There are 2: The Thing in the Depths and, more significantly, The City of Corsairs (more than 10 tries to win this scenario). You might want to pair the deck with a more combat-focused deck for these scenarios. I included Fair and Perilous mainly for these corner cases.
I think Revealed in Wrath triggers after Boarding, so you would have to play it in the encounter phase to avoid Boarding (I think that's what you meant in the description, anyway).
