If you dare try and make Horn of Gondor work in an eagles deck, this is the best chump blocker in the game. Essentially a free boost to Eagles of the Misty Mountains. The only problem? You have to have an Eagles of the Misty Mountains in play for this combo to work, at which point you may not be hurting for resources.

Reviews
As the only 1-cost Eagle, this is highly desirable for expensive Eagle decks. It's not half bad outside of them either - as a matter of fact, the only other 1-cost ally in all of Tactics is Knights of the Swan, who's useless on his own. Vassal is a nice damage spike/potential chump blocker for little investment, in a sphere that tends to lack money. Also a good target for Support of the Eagles when you don't have time to build up an Eagles of the Misty Mountains.
