I do not think it is the ghost rider type spells that are the real
problem. In a game with Cohen, I was running a variation of this:
the firing squad province. I had about ten sages, an arch seraph,
and a few defenders. The 'wind ridden' commanders were tried,
found guilty and executed in a very efficient manner. I was pestering
him for a few turns, snatching his merc commanders on the turn he
renewed their contracts, splitting his devil armies in two, etc...
He did attempt a few attacks on the provinces, but the sages held
their own (frozen heart and false horror are quite unpleasant)

I was sure that I would soon be at the receiving end of some seeking
arrows or flames from sky, and that would be the end of the joy rides,
given that I would have had to dome the province, or lose expensive
commanders. Fortunately, I happened to snatch his pretender and then
the commander of his Last devil squad... and he quit on turn 22.

But the point of all this was that if you have a province like this,
you will probably be arrowed or flamed.
