Play against Necropolis.

What does chaos have to do with it? Necropolis doesn't have it in their guild... they only have summoning and darkness! Orcs are created for attack; there's no point for them to sit in defense against any opponent!!!;)

I disagree. The Academy (I'm mentioning them because they are the only race besides Necropolis with magic as their main attribute) are created for attack, but they don't have much defense – you won't be able to sit in defense for long, and even with three units, without any tactics or speed auras, they can reach the opponent – this fact speaks for itself. And what about Necropolis? Who among them has initiative or can move quickly? Only the new vampires have a speed of eight, but who uses them? And even if they remain alone in the enemy's camp, they won't last long. No, Necropolis is precisely a defensive race; their second attribute is defense, and that skill is well-developed, and their units are not suitable for a rapid attack. The hero will first weaken the opponent with darkness, and the troops will finish off the rest.
