Killing mages in the back

[Redeyes]

I also think that works pretty well, Foodstamp. You are right on the names

If you can get the proper resistance wrathful skies/heat from hell and other battlefield enchantments are pretty efficient at taking out weak commanders like mages usually are. They aren't immediately effective, but if you set your army up so it holds back in the back row you can easily win a long range war of attrition. Caelum is especially good at this, but other air nations should be able to do it pretty well too.
