If you can't defeat an enemy with this, it's not very good at two damage for 1+card. If there are any minions in play, it's usually easy enough to tee one of them up to be defeated, and then you can get four damage for 1+card, which is pretty good.

Shout out to Ms. Marvel who can Embiggen! for a fantastic eight damage in total.

With Winter Soldiers Cybernetic Arm, this is a really efficient minion removal tool. This effectively reads as "kill a 3 health minion --> deal 2 damage + remove 2 threat (with Winter Soldiers ability) and is quite consistent to trigger

In other heroes you can run Aggressive Energy and get more value from this, but that's hardly reliable
