On the other hand, CBM makes iron corpses worth the gems because you can just get so damn many of them. You'll still be in real trouble if you run them up against people who can take control of undead units thank to their horrible MR, but at the very least you can get a serious amount of them for relatively little cost.

That reminds me that I should finish my LA Agartha guide. Especially considering how many bad advices are floating here.

Cast Antimagic first turn. It's easy, cheap and effective.

Edit: Oops, maybe not so easy. I thought you could get S2 reasonably comfortably from LA Agartha, but on checking it's actually pretty rare.

Re: LA Agartha Advice Wanted
 

at the cost of 30 gems to empower a single mage to S2, and from there the ability to forge both crystal coins and starshine skullcaps, I would think this tactic is easily in the picture.

There is also an earth spell that raises MR in a small AoE. Though maybe not right for this situation since there are potentially 100's of units.

An amusing alternate build for LA-Agartha.

Seems to me the problem with argatha is rapid expansion.
I happen to like a phoenix.

I look for something like an A2-4 F4 phoenix. However you can profitably mix in blood and/or earth.

Besides blowing up, the phoneix lets you gift of flight either your heavy cav or even more amusing flame corpses.

Phoenix: GoF
Corpses: Attack rear.

They usually spread out quite nicely - and first turn your enemy units are often quite near their mages. Who expect agartha to fly?

Blood on the phoenix give you mixed communion / sabbaths. With Death and blood, you're ok in endgame.

Additionally, some of your hero's are undead. And so make pretty good prophets for reanimation.
