As LA TC, you have many of the tools you'll need. His risen oracle is immortal, and that makes dealing with it really, really annoying. But, as long as you can expand faster than him you should be able to keep his dominion out of your lands and make him rely on defense. Does his risen oracle have immunity to all of the elements? If he's left out lightning immunity, then hit him with that. Stellar cascades and ghost grip will cause him fatigue as well. You also have mages with both nature and death magic, so have them cast eagle eyes, then dust to dust. Put herald lances on several khans or bane lords and have them attack large enemy monsters. Flying bane lords can attack him before he gets any buffs.

For his lifeless constructs, the spell you probably want is shatter at alteration 5. You could also try thugs equipped with smasher, but I'm not sure of the exact effects it has on them.
