Thanks for your answers!
I've never used slingers yet, I'll take a look at these.
And Tifone, what do you mean by "archer decoys"? These are the little shielded squads in front of an army to catch arrows?
By "low level demons to protect my own land" I meant that I couldn't stop AI huge armies with my jags, so they invaded my lands before I could get ritual of the five gates or other high level spells.

And I will try ozelotls, I have never made many of them yet.
