Simply, Angbor is a 2 cost for 2 Willpower ally, and he can help attack if you're in Valour. Solid if you ask me.
Nice traits as well. Gondor has enough ally buffs in Leadership alone that you can get solid mileage out of 2 cost for Angbor, even without the Valour effect. Leadership Boromir and Visionary Leadership immediately come to mind, but I'm sure there's more. I've used him as one of a handful of "permanent" allies in a Lothiriel deck to decent results as well. Nothing revolutionary, but solid for sure. As a fun note, compare him to Guard of the Citadel from the core set. — Láthspell 1
man it'd be nice if he had the outlands trait like he should have in the books (but he's already great so it'd be OP :) — BlackArrow 265
That's what Sword of Morthond is for! — kjeld 480
