Based on everything mentioned above, my conclusion is as follows: The Swamp Castle is strong on S maps and possibly on M maps, but it will hardly be able to compete with other castles on XL maps. The Fortress's strength lies in its rapid development at the initial stage, but then things go downhill because others catch up. Its creatures are not particularly powerful...
How many threads are there about the swamp? It seems like they discuss the same thing everywhere.
Read here; they have already described everything in detail:
/topic/3873/
According to preliminary data from online games of the winter season on this portal, the Swamp Castle ranks 4th in terms of the number of games played with it compared to the number of victories achieved with it. For comparison, I can say that there were more than six hundred games in total during the season. After the season ends, I will publish more accurate data here (or in another thread about the swamp – how many of them are there?) if anyone is interested.
P.S.
The Gorgon has the highest health and defense among creatures of her level. However, her attack, damage, and especially speed significantly reduce her combat effectiveness. Her Deadly Gaze is certainly very good, as it usually deals more damage to creatures of levels 7 and higher than her regular attack. But if you don't let her get close to creatures of levels 6-7 (which is quite possible due to her low speed), she loses all her usefulness.
