Paralyze, smite, soul slay, even a couple of knights of the chalice(provided you get the charge with your knights) or a big group of greatswordsmen should do the trick. IIRC black hunters are 125 gold and quite a few resources each so you should easily outnumber him and alot of your troops do alot of damage so you should have alot less trouble than some other nations might.
