I'm a sucker for an army full of summoners. With the right talents to remove morale penalties, I like to use royal thorns, royal griffons, druids, choshas (I forget how to spell it... big worms that make tiny worms), demonologists and necromancers.
This time around since I can't get necros or choshas I have used engineers and rune mage for summoners (haven't found any demonologists yet).
And I'm loving that my upgraded ice spear adds +1 ice damage to the attack of my stupidly plentiful summoned thorn warriors. I'm only about halfway through and I've seen a stack of over 2,000 of them plop out of my royal thorn.
