Create Revenant to summon Banes. Reaching Enchantment 3 takes some research, but you get useful death spells and can use the mage for something better. And you might need Mound Kings to lead your banes... It depends on your death gem income, though. If you get death gems enchantment will propably be worth it, but otherways it might not be worth the work.

If you get your death priest animating dead, Marignon's mage-priests will most propably Banish them instead of casting something else. But then, it might not work and they would fry both your mage and the dead man with a Holy Pyre.
