What is your opinion about neutral creatures?

Yes, yes, I was asking about mermaids. So, I wasn't mistaken. Well, they are strong. When I'm not sure about my own strength, I don't engage in battle; I try to avoid it. Once, there was a situation where the enemy had more troops than me throughout the entire game, but when he encountered the Fish and Mermaids, almost his entire army was wiped out in one go. They accumulate, and the closer to the end of the game, the more of them there are.
