When I first got into the game, upon seeing Legolas's ability, I thought, 'Hey, could you win without questing at all?' — Not as a power-deck, just as a game. I made two decks early on, but didn't know what I was doing and never tested them. (Aurion tried with this deck, and got close, but did quest a character or two.)
But after some experience with the game, my son & I decided to try again, and built this, and it worked. We beat Passage Through Mirkwood (yes, the easiest quest) three times without questing a single character. (The third time was so that we had done both versions of 3a, since we got the one with Ungoliant's Spawn the first two times.)
I don't know how many other quests this deck could beat (without questing anyone, I mean); it would probably need some real revisions. But hey, it was a fun challenge to do.
(The sideboard lists cards we thought about using but didn't, just to remind ourselves, in case we wanted to change our minds, or try them in a different quest.)
