The 3rd stage of the annual John Van Caneghem Tournament (2007).

I remember Sage mentioning a similar battle tactic during the BestOfBest tournament. The main thing is to protect the ammunition cart and snipers with a force field. The mana issue can be solved :) Fireball!! - respect - awesome :) I was confused by the cursed ground under 25 Castle. And I abandoned this idea. Now, with my comrades, we easily handle it :) 9 Angels with healing make it work, even without high magic.

I eventually used this tactic, but much later. The problem was that the Dark Fortress kept destroying the cart because I couldn't protect it with a shield. But now I understand that I just needed to fill all the hero's slots. Then the cart would have moved to the corner, and I could have covered it with a field along with the snipers. The question is, you need a lot of mana, and let's see how Fireball solved this problem.

I had 5 archers and 1 angel, but without a specific tactic.

Where did you manage to upgrade to archers? That's an extra 2-3 days, if you're upgrading on the left.

And what troops and their arrangement, and what hero skills did you have before the decisive battle?
