Here's the excerpt from Mizrael's post where I read about using Antimagic on enemy Archons:
"Mizrael - Javdet 2-0
First battle: Rampart-Inferno vs. Tower-Castle. I took Fire, Offense, and Defense, Berserk, +4 Spell, 40 mana, and boots of resistance. After the wait, I wait for the cast, they blind my Devils - in response, I cast Blind on the Archons and get the first speed for the next round. Then I attack with the speed advantage, and it doesn't hurt much when they attack under the curse; I use Antimagic on the Archons." (c). And I don't understand what I was doing wrong - but Antimagic, as it was written, can only be cast on your own units:confused: ...
