Not a bad weapon for Lore! If you have card draw (which you should if you are running any decent deck ;) ), then you can get definite use out of this baby. Reminds me of Protector of Lórien from the Core Set, except it's damage instead of attack boosts. So less effective against certain enemies (looking at you Uruk-Hai!), but also good against enemies with high shields, as long as they're not ITPCE. Also, the hero gains ranged, which is nice.
Can definitely see this in an Erestor deck, and maybe Beravor of Ori could get some use out of it. Not an over-powered weapon, but hey, if you want those, go play tactics!
