Maggots is also good against SC.

You may wish to consider, that his best beasts are going to come from very specific territories: woods with temples.

And since he doesn't spawn undead leaders (that I recall) you may well find it worthwhile to hit it with remote summons.

Leaderless Undead don't route - they pop. After the first time however you will probably have to hit each territory with 3-4 remote summons.

If you take the territory: gravy. Even if you don't each round about 25% of the beasties will die.
