Which level 7 creature is the best, and why?

Ancient Horrors (they sound ridiculous, like Hippos) are the most unbalanced monsters. If you compare them within the context of the entire game, not just a 1v1 battle, they are the STRONGEST. Although, more accurately, they are the most... cheaty. You can obtain a Horror on day 6-7 (if the option for level 6 is enabled – on level 7) of the first week. This says a lot. Firstly, it means easy clearing of all mines, wells, etc. And secondly, it provides a real opportunity to defeat 1-2 opponents, as you will have the strongest army (I don't know who, besides the Horrors themselves, can beat you). I don't know who would argue with that. And 1v1 is nonsense, as it rarely happens in a real battle, and if that's the case, then why compare it?)))

This is all, of course, just my IMHO – but my IMHO is not just four letters on a white background.
