How about the "mile wide mass of False Horrors"?

Unless he has fireshield, an Ice Devil can kill a maximum of 4 units a turn. If you can thus bury him in about 200 false horrors, he can't win, as long as you're defending. They might even, but I wouldn't count on it, kill them. Otherwise, you need to roll your own SCs, like, say, Air Queens, which should be easy enough to get for Caelum. Throw in a burial of false horrors, and use your AQs for punch, and you can probably take 'im down.
