Necropolis and Demon.

Demons, in fact, are significantly less protected than necromancers. The defense of a demon hero is practically zero compared to a necromancer hero. Even if the demons manage to play without losses (which requires great skill, especially at the beginning, since they practically have no archers), even in this case, the necromancers will have more troops due to the use of dark energy (at least until summoning from the gates). But, in reality, I myself would bet on the demons; I have already written about this.
