By the way, why can the AI control Berserkers? You can notice this during a castle siege; they just stand in place.
It shouldn't be like that.

As a rule, Hydras are weaker than Black Dragons. You can choose them against Barbarians, or when you lack resources for Black Dragons, or to surprise your opponent, but... firstly, they are slow. Secondly, their susceptibility to enhancements is good, but against, say, a Haven Mage, Hydras are a death sentence for yourself. They will be hypnotized, slowed down, teleported, and subjected to the Song of Peace, etc... P.S. Titans on the Tower generally defeat everyone, but there is some confusion. And Hydras definitely won't reach them in time, unlike the Dragons.
I actually won against Shnurov playing as Chaos with Hydras and Nightmares. He was playing as Haven, had amassed Titans, Nagas, and even had a Sorceress.

More details are needed here!))

One antimagic spell – the dragons just snarl menacingly.
Devils can be summoned not only by nature. Demonology is equally accessible to both nature and death.
I was just playing against 7 AI opponents on Champion difficulty as Nature.
