There is something to be said for testless damage. Sometimes, being able to just reach out and finish off a foe can be really, really good.
This card is in an odd spot because you basically have to have a foe that is "softened up" beforehand in order to get the most out of the testless, conditional one damage.
Beat Cop and Ambush can do that, so they are worth mentioning.
Also, Zoey's Cross can soften up your opponent for the final blow.
That means you probably want Taunt or Let Me Handle This! so that you can reliably trigger this card.
Ultimaltely this is a support card that might be just a bit before its time. It isn't a lynchpin card for an archetype, as all it really does is let you either finish off a wounded foe or sprinkle some damage on them. I anticipate a weapon or effect in the future that keys off of "damaged enemies". Until then, this card probably won't get a ton of play (outside of some Expert builds that value the testless damage).
