In Heroes, when experienced players face each other, luck and attentiveness become the key to victory. It all depends on who has gathered more troops, found more artifacts, and mastered magic.

I agree that when experienced players are involved, luck and attentiveness are crucial for victory.

Who is stronger, the Archangel or the Devil? Which artifact is better, the Centaur's Axe or the Sword of Justice? What does a specific type of magic mean, or what does a specific composite artifact consist of? This won't work with me; I think I know everything about Heroes and have reached the highest level.

I'll say it again: it's highly unlikely that there's a single Heroes player here who doesn't know all of this. But that's not a guarantee of victory, is it? A chess player can't be unaware of how a particular piece moves. But how they move it is a different matter.

But I don't have any experience playing Heroes online, so I'll be a bit hesitant.

Playing against the AI is enough; you can take 30 seconds per turn, and with a bit of luck, you can even fight battles over a couple of weeks on auto-battle. I myself have only recently started playing against another person. I'm bringing all this up to suggest that you somehow increase the turn limit and give players enough time to think. I would like to participate in the next tournament, which is why I'm bothering everyone with this question. :)
