Congratulations about the victory, and some points:

10 Nature Dragon isn't as good at summoning Lamias as 9 Nature (green) Naga. That one gets a Lamia summoning bonus, can use more items in battle and still has pretty good stats. The 10th pick of magic costs a lot, so Nature 9 would probably been enough. You would have gotten 1 lamia less pre summoning, and you units would have only lost the last point of berserk from their blessing.
Machaka Hoplites are very good infantry, and Machaka Archers are very cheap. You can make lots and lots of them, and your Black Sorcerors can cast Flaming Arrows... You researched Enchantment any way for Gift of Health, and it would have only taken some extra gems, or casting Phoenix Power first, or lucky Black Sorcerer with his random in Fire, or research in construction and Flaming Skull (1Fire 1Death miscellanous item, boosts Fire by 1) to be able to cast it in all major battles.
