What do I build to counter High def glamour units?

[Action]

This isn't another balance thread about van/hel heim balance in multiplayer blitzes (whatever those are). I've never played multiplayer.

Rather, it's a more basic question, about single player.

What type of units should I build to counter the AI Helheim's high defense glamour units. These units aren't really blessed, at least not often. It's not just the helhirdlings, the non sacred cavalry tear me up too, and the glamour infantry are pretty hard to kill as well.

For example, Last turn I had a block of Sarmation Amazons and the AI glamour cavalry (unlessed) will just ride up to em and kill them all, at like 4-1 odds, taking no losses, and often not taking a point of damage.

These Cavalry have 19-20 defense plus the glamour ability, so units with just a medium attack ability seem to be unable to scratch them. They don't kill my Amazons super fast, but they do steady damage and my amazons can't hit them at all.

I tried Cavalry, but the Sarmation cavalry has low attack as well, and gets torn up even worse than the infantry, since it can't gang up.

I've had my best success with archery, which deglamourize the infantry pretty well, but against the cavalry, it's tougher. They move very fast close into melee range quite quickly. With 11 prot and shields and the glamour ability, they survive the arrows quite well although they do take some damage, my troops take a lot too. The AI also has a 70% air shield bless, but lucky for me he doesn't actually bless them.

So, my question is, what troops should I be building to counter these guys? It doesn't have to be Sarmatia specific, just in general. I'm not losing thanks to my Gorgon, but this is the first time my troops have been outclassed this badly in quite a few games heh.

Right now the only way I've really had success is routing them with fear spells after killing their buddies, and my Gorgon pretender who could probably kill an unlimited number of them, hehe.
