I played this theme Last night, against all the AIs, minus Ermor and Jotunheim (because I didn't want them to get the Utgard theme) on Orania with 9 indeps. I picked 3 order, 3 misfortune, the requisite 1 sloth and 3 magic, along with a bunch of Earth magic for my Cyclops pretender and a not too strong dominion. I couldn't spend all my money fast enough, so I bought lots of mercenaries, spread out pretty fast, spread my dominion like mad, built up some of my Dark Citadels at the outskirts of my little empire, and had my billion or so cheap researchers go all out towards the Riches from Beneath (not sure if the name is right) spell, to improve my productivity. Soon, within 40 turns, I had my Dark Citadels producing Myrmidons by the swarms, had Marignon and Tien Chi dead and had Caelum and Ry'Leh on the ropes, and had a big ol' stream of research. Then Abysia and Pythium brought me down a few pegs. Now, at like 80 or 100 or something (it was 4:00 AM when I stopped playing, a bit hazy) I had three research paths to 9, most others to 4 at least, summons out the wazoo, Kings of Earth Elementals slaughtering everything in their path, being decked out in an absurd amount of equipment from my Mystics and the Forge of Ancients spell, and was steam-rolling everyone, with way more money than I can spend. Seeing as how every game except one up to this one, I lost, (and that one game was really hard and into 150+ turns on a small map)and I'm freakin' annihilating the enemies right now, I'd say this theme fits my playing style.
Although I haven't used the skeptics as often as I thought I would . . .
The Myrmidons are very strong. I like them a lot. They form the core of the army. The wind riders seem to me, as mentioned by a few, as sorta useless. The chariots do well against weak indies in bunches, with some fodder elsewhere for the arrows.
