you could kill at least 1000 Archons

Actually, it's less :) - about 20 minutes. Someone posted a similar example of killing 1000 Imps in this thread; download it and see for yourself. Everyone keeps claiming something, but why don't you just check it out? Is it that hard?
Sincerely.

I understand everything perfectly! If we take an Imp as an example, will the slow effect and other things work first? And tactics are needed so that you don't have to deal with speed and instead place a peasant where (in a 2x2 area :D - sorry for the pun) he can't be reached. Is the Imp's speed 9, and the slowed Archon's speed 2 or something?

Well, you're quite something! You say you understand everything, but you keep defending your point of view (which, on the one hand, is good ;), but only when it's justified!). But what does tactics have to do with it?! UNDER NO CIRCUMSTANCES CAN YOU SAVE THE PEASANT!!! You can't hide a peasant from an Archon, even if you have expert tactics - THEY WILL GET HIM ANYWAY!!!
Yes, the Imp's speed is 9, but the slowed Archon's speed is also 9! Still, if you attack, you go first...

I thought that even using Berserk, you would only have to stop about four of them, and the rest...

And what does that have to do with anything here? Have you seen the map!? 1000 Archons in one pile! But even if they were in seven piles, it would be MUCH easier (and faster)! Your turn-based rule: cast a force field, then Berserk, then force field, etc. - THAT'S IT!

Yes, I wanted to say right away that if there is any aggression in my words, I didn't mean it and I apologize...
But only for that!:):):):) - as D'Artagnan used to say.... :D

It's okay, don't worry about it :)
