I've noticed that strangely, Machaka has lately been a real problem in SP games. I think it's the reduction in cost on spiders. The guide's advice on massing lots of these guys is still helpful. For the early game, take some production scales and pump out spiders and hoplites.
The Black Hunters seem to want a bless badly. The rider isn't too important, but the spider is pretty handy. Expensive, though.
Since you have plenty of F magic, Zmeys are an obvious target. Flaming arrows too if you're confronting chaff. For SCs, the death direction seems appropriate. But your E mages should be able to create cyclopses too.
Just random thoughts -- I'm not very good at this
