Watcher of the Bruinen is a card I've never really use much, probably due to Tactics' card draw deficiency. He is however, still a pretty good card despite the fact that if he's taking so many attacks, he'll probably be destroyed. He does synergize with the Noldor stuff like Mithlond Sea-Watcher, but the only Tactics Noldor hero is Elladan; who mandates some version of Elrohir. Still a good card.
