Claymen cast by W9E4 Daughter of the Land are surprisingly cheap...
And you also get Reanimation, Raise Dead/Skeletons and (although these aren't low-level anymore) Undead Horsemen, Banefire Archers, Enlivened statues and Demiliches.
I would love to get W9EX and Golem Cult, but there aren't many nations that I play so that they benefit from Magic 1+ and Prod 1+... And I don't think there is any that benefits of Enchantment in those, or any which would benefit from W9EX or WXE9, or even W9E9 enough for it to pay off. Golem Cult-boosted Claymen and Enlivened Statued would be interesting, but the need for both production and magic is a killer that puts off all Earth nations... Ulm takes drain and has no blessable units, Vanheim and Pangaea benefit of both blessings but need sloth to pay for extreme pretender.
