Necropolis versus Academy.

The point of taking light creatures in a late-game battle against the Academy is as follows: firstly, you need to defend against Armageddon, that's one thing, and secondly, you need anti-magic to prevent the use of Sandro's Cloak. And of course, light spells will also be a nice addition; mass evasion and stone skin will come in handy, because the mages have a lot of archers in their units. And of course, fire resistance. And you can also take Twilight creatures.
Now, another question. I don't want to create a new thread, so let's discuss it right here. The question is: how to defend against the Necromancer's Armageddon when using the "Horde" skill? I'm really struggling with this.
