Yes they are are 100% resistant to lightning, fire, posion and cold. However, one of there weaknesses (surprised no one said it) is they are size 2. No doubt caelum will have alot of expensive mammoths who after the expansion phase (or during) would love nothing more than to trample some size 2 mechanical men into the ground. Even with 16 hps from golem cult those mechanical men will be crushed, sure you will lose alot of mammoths but you want to lose them before mid game anyway because of the expensive upkeep.

Also, does weapons of sharpness make the weapons magical or does it just give armour piercing? If it does not make the mechanical mens broadsword magical then body ethereal on mammoths or caelum protection 20-22 (in cold 3) iceclads will defeat those mechanical men. Caelum can also bring quickness and luck to the party without any real effort.

Also, when spamming lightning doesn't the AI account for SR 100% and avoid targeting those, so would instead target those mages of yours? Not completely sure on this one, I am constantly forgetting and remembering Dominions rules.

Remember, everything I have said Caelum can do is gold recruitable. Pretty much everything you want Ma Agartha to do is via earth gems. You will run out of earth gems alot faster than Caelum runs out of gold.
