Actually not that bad of a card. Especially good on allies (not so much on heroes) that do nothing after triggering their "enters play" effects. Slap one or two on your Guardian of Ithilien or your Andrath Guardsman and just deal some damage continouusly. Works really well against those pesky "cannot leave the staging area" pseudo-archery enemies like the infamous Golblin Sniper from the Core Set, since those enemies often tend to be low on hitpoints.
