Enter the Hill Giant Barbarian. For twice the cost of an Orc Champion (a standout Archfiends unit for Chaotic Evil), you get two attacks at +12/+7 for a whopping 35 damage. The HGB is the second mini previewed with Overwhelming Size, giving him another +2 to attack and +5 to damage when he smacks a smaller foe. With Speed 10 and Melee Reach 2, he can threaten a lot of board. Even if he gets only one swing after moving, chances are it will hit and hurt badly enough to force a morale save. The HGB isn't Difficult, but he does take 5 points of damage each round for the first two or three rounds because of his Furious Spirit -- not that you'll miss 10 or 15 hit points out of 155!
