Terra dei Demoni

With such a banning system, the number of options is reduced to exactly two - red Tower vs. blue Barbarian and Conflux vs. Conflux. If the red or blue player tries to deviate from this direction at any stage, they risk ending up in a losing situation. I'll explain why.

Firstly, each player must ban at least 5 towns for their opponent - Necropolis and 4 double-builds. This is unavoidable; if red does not want to get into trouble, he must start banning them - because blue has the last word, and he can use it to help red postpone a good brick setup. I'll demonstrate using Necropolis as an example - if red does not ban it for his opponent, blue will do so at the very end - and will play Necropolis against any other town, which for red is equivalent to defeat on this template - we've already established that. By the same logic, red cannot leave double-builds for blue if he does not want to play against a double with a normal setup, which is also not great. Blue, of course, in response must act synchronously - he cannot leave such advantages in red's lineup after losing them himself, can he?

So, both players have already used 5 bans. Now, in turn, blue bans Dungeon and Castle for red - because he absolutely cannot let red keep these two strong towns - he loses the benefit of having the secondary skills of these factions, such as Angel upgrade and at least double mana with Portal. And now red is forced to react - removing Rampart and Fortress from his opponent, also two formidable towns.

And now each player has one Conflux left, as well as Tower for red and Barbarian for blue. So what will red ban in this situation? He can proceed in two ways - ban the opponent's Conflux based on the considerations mentioned above, and then it will be Tower vs. Barbarian, or ban his own Tower, and then it will be Conflux vs. Conflux. That's essentially the conclusion I came to after thinking about it. Of course, I could be wrong, so if anyone sees a mistake in my reasoning - I'd be happy to listen.
