Air mages love spamming ghost wolves / phantasmal soldiers.

In fact, the AI seems to put a lot more weight in general on spells that summon new stuff on your side, as opposed to spells that try to destroy the other guy's stuff. I suppose it makes some sense in absolute terms, since adding one soldier to your army always works 100% while zapping the other guy might miss or fail to pass MR, but it's often silly in practice.
