Well, Mictlan had a few battles with a couple Pythium armies that were in Bandar's lands, I seem to remember a few Hydras, and also a largish infantry army. But since I was attacking their expansion (Bandar) I didn't have to face their capitol mages or thugged-out god. I think my flying Eagles of Doom (TM) would have been useful though. And I was even considering an assassination lightning strike on Pyth's god, until I realized that he was doing me a favor by punishing you so much.
I didn't fight C'tis either, just a Jotun army, and Jaguars of Doom (TM) are giant killers. And since I was attacking Jotun's expansion too, I didn't need to face their home guard of mages either. It's good timing to attack a nation's expansion when they have just finished (or almost just finished) polishing off the previous inhabitants.
But I think in both cases I would have been able to handle a "real war" quite easily. I never lost a group of warriors since turn 1, and put up my third fort at the end of year 1, and never took a break from recruiting sacreds. Dom10 to start equals lots of warriors. Mictlan does not need battle magic early on, so I rushed const-6 and built a ton of lanterns. I was lucky to find a couple Enchantress sites (though C'tis and Shin could have had them too), which helped me do artifact forging. And I also managed to pump out quite a few clams early on too.
By the time I got in a war with Shin, I had Fog Warriors, and Fog Warriors plus S9F9 blessed warriors is nasty. Plus I have Rain of Stones to eliminate pesky mages.
The biggest threat to me all game was R'lyeh, with their Burden of Time. But since I had the Chalice, and my High Priests can trapeze, I didn't even lose any of them either.
Ermor was a big threat too, but I'd been saving fire gems for Purgatory, and it's still up, and now I've got even more fire gems saved up to recast if it comes down.
We can continue if Pan has some nefarious scheme for victory and would like to keep playing, but my tartarian factory is opening very soon, so the future does not bode well for the halfmen. I've also got more Golem SCs in the pipe to handle Pan's large manikin forces.
R'lyeh is always a pain to invade, but Oceania is doing quite nicely against them. And I think they only have 10 candles left, and once I've filled Shin's empty provinces with my dominion, I'm quite certain they will be dom killed before Oceania reaches their capitol.
Oceania was a huge help, with their ability to take on R'lyeh. And also for getting me into this whole big war in the first place ... if Oceania hadn't asked for help against R'lyeh, Shin would never have feared the "Oceania-Mictlan alliance", so he would not have attacked Oceania. There was no "Oceania-Mictlan alliance" to speak of until Shin attacked Oceania, and I think Oceania and Mictlan may have never even agreed on a NAP.
So, if anyone wants to continue, I'm game, but I'm also willing to call it a victory for Mictlan here.
