I got completely paranoid about getting flanked if I attacked anyone - plus my research was something like half of everyone else's for quite a while (though I closed that gap rapidly once I got Cons-6 and blew ~150f on lanterns over the course of two turns).
I had a large stockpile of mandragoras to shred your glamours (12 magic attacks per square will do that pretty handily), and I'm pretty sure my sacreds would still be able to massacre anything they met at this point so long as they weren't grossly outnumbered. It would help, of course, that my top Hall of Fame prospect had been drilling them with an Ancient Master for the last who-knows-how-long so at least half of my 200-ish were level 3+ (some were close to level 5) and thus individually had high enough Attack to rip through thug Defense unboosted (and the Strength to pop Fog Warriors right out of the gate) - and once they berserked they'd have high enough Attack to take on a fair range of moderately Defense/avoidance-oriented SCs even though they were only one attack per square. And that would be with nothing more than a bless for boosting. I will admit the massed Lifelong Protections could have been a PITA for them, though. Not insurmountable, but definitely something requiring support to overcome. My demon knights were piling up, but for the moment only 10 of them were training, though I was seriously considering shuffling around the site users so I could instruct more Demon Knights.
All in all, it would have been messy, but likely interesting. I really didn't have a grasp of just how evil my sacreds were for the first year or two - I knew they were monsters against indies, but when I had 5 plus an H2 kill 20-ish of Karlito's giants (with a prophet leading them) with 0 casualties, I probably should have taken that as a sign to go on a rampage even if it meant I might get swarmed. I'm so not used to playing strong sacred nations...
