Well, they are casters. They simply can develop a spell that autokills every non caster. Every caster can recognize the type of an unit, so it shouldn't be a problem to create a spell-trap that only is activated by non-casters. And if it's a problem, well the magic kingdom is the place to solve that problem. The guys who made an search&summon spell that can find the perfect warlord anywhere in the universe should be able to do that.
or, more simpler, develop a portalspell that is only usable for casters.
