Call of the Winds: I hate knocking down castles. I like small armies of relatively elite units, or else regular units with combat mages, and so having to build a bunch of militia to besiege a fortress irritates me. That makes Call of the Winds a great spell. The hawks you get aren't upkeep-free, but they're not expensive, and they appear anywhere you send them. After the siege you can use the commanders as flying shuttles to collect routed troops, ferry gems, carry Wall Shakers quickly to other castles, etc.

Cloud Trapeze is great because anyone who is capable of casting e.g. Shimmering Fields is also capable of dropping it on enemy armies anywhere, before they get a chance to even move. It's a terrific strategic spell in a school that's already nice tactically.
