Great value if you can get the heal, fine-but-not-great value otherwise. You can boost its damage using some combination of Honed Technique, Aggressive Energy, and Warrior Skill to make it easier to finish off an enemy. It also conveniently has a resource itself, making it fit especially well in Honed Technique decks.
Hero Action (attack): Deal 2 damage to an enemy. If this attack defeats that enemy, heal 2 damage from your hero.
