I generally prefer, if I'm being honest—the Swamp or the Barbarian.
The same for the swamp - a ton of Wyverns... you know where to get them, besides the population))) Magic Gorgons...."- where are the Black Dragons? - Let's see... closer, how many fell from Death Gaze? Well... don't pull your hair out."
The Barbarians have Behemoths (that's what we call them) or Ancient Monsters...- Now these guys just don't give a damn about anything. They approach someone with bloodlust and minus one unit:) (well, except for those same notorious magic gorgons, and I really don't like dendroids either...)

Well... the most awesome game was when I played as THAT very Conflux and I had Armageddon... It doesn't affect Fire Elementals, magma elementals have zero emotion, Psi-elementals... also no, Phoenixes live there)) And? my first turn and simply minus half of the enemy army... which stack is the fattest? - yeah... we fly in with Phoenixes and wipe them out. In case of misunderstanding, the dose is doubled)
