Counter-heroes in duel mode (3.1).

Watched the latest replay. There were many mistakes made playing as Ravenna, plus the artifact that increases magic resistance on the Steel Golems made it impossible to defeat them with cold damage. I won a similar game playing as Razazak in version 3.0; there was also an artifact on the Golems, many summons for Ravenna, and ultimately, I won.
I think that even with good gameplay, Razazak still needs some luck to win against Ravenna, and quite a bit of it.
