Caelum works well with the "Holy bolts of Marignon" trick. That is, run a air10 pretender which renders your blessed units almost impervious to missiles and then use those high precision archers of Caelum on Fire Closest.

A number of iceclads kept in the rear and set to "hold and attack archers" will make short work of most leaders and pesky archers while your main forces deal with the infantery.

Since your pointmen would also be invulnerable to lightning and cold you can let loose all kinds of trouble with spells and summons without worry about attrition.

Mix ordinary wingless with mammoths, to improve the tramplers morale, and use this force to flatten "warm" foes.

Finding nature mages is top priority since you'll need to craft supply items to feed your winged battalions.
