A great card for any deck that attacks enemies in the staging area. Heroes such as Éomer and Dúnhere really love the 2 boost from the card when attacking enemies in the staging area, and the cheap cost of one resource is nice too. This card works well with Dagger of Westernesse (to improve you chances of drawing an useful weapon attachment), and really makes staging area decks a lot more consistent. Of course, the card is restricted and is limited to Rohan characters, but that's alright because the only other characters that attack enemies in the staging area are Haldir of Lórien and maybe Bard the Bowman with a Great Yew Bow.

In single player, attacking enemies in the staging area is rather niche because only one encounter card is revealed each round, making it unlikely that an enemy will appear on a regular basis. However, in multiplayer these decks are far better (and really fun) due the the greater number of enemies revealed. Not the most splashable weapon in the world, but it the right deck, it works very well. Give it a try, it might surprise you.
