I'd rate this lower than Ancient of War, and even that only sees play because Druid can ramp. The quest makes it a little better but I think even still it won't see play. Maybe as a one-of and I think even that is greedy.
Am I the only one who thinks this card is horrible?! Anciant of war for Warriors BUT you only deling ONE damge to your oppent. Thats a major draw back exspecialy for a 7 drop. Not to mention if this card ever be played in a cometative deck evryeone gonna run silences and Black knight.
