A super unit could then be any hero. Here's a super mage:D (from Haven)
But still, the Barbarian's resistance and ranged attack will give the Chaos or Haven mage a good beating.
P.S. It will be fun if Berserk is cast on monsters standing next to the hero (especially if there are 30 or more of them:D) or, at worst, on Cyclops. Against Haven, the Barbarians have little chance, unless their army is ten times larger than Haven's.
