Has anyone tried to do this with giant nations? There's one case where reanimating priests would actually be great.

It's easy to kill the targets. The secret is in auras, obviously. 10 Winter Wolves set to guard cold-immune commander will kill his two non-immune friends in few turns. Bog beasts do the same even faster. If you do this with indy priests and get back Longdead Giant/Rephaim reanimators, it's worth the trouble.

The main problem with auras is that you need a fight that last for 5 turns or so.
