I wouldn't know about the AI's ability to micromanage more quickly, since this is a TBS, but a few hints:
- hit them with inquisitors - banishment and holy pyre, also purgatory GE
- counter with your own summons - blood or anything else that needs not eat and you can summon in large numbers, which depends on your gem income - vampires & lords might work well, since lords can cast dust to dust etc.
- hit them with assasinations and assassinating spells to take out priests and undead commanders/mages - undead cannot work without them, and cannot be summoned either
- try to quench the undead nations before they become serious problem (early in the game) in future
- recruit even more inquisitors after all this is done
Good luck.
