Fortress vs. Necropolis

It's not just the start; the game goes well throughout. And when you have over 300 of them, the opponent has to really try hard to defeat them. Plus, you can always take mass Stone Skin as a precaution. Another great thing is Phantoms. If the Phantom Zombies manage to get a turn, it's really bad news for the enemy! Vampires from the Darkness faction also look good; they'll definitely take a long time to defeat, but the main thing is to try to find the Celestial Shield. Without it, the endgame will be a bit more difficult. I don't know about Vampires, but when playing as many factions, Vampires are one of the main targets against Necropolis. And they rarely withstand attacks from units of levels 5 to 7: Unicorns (some of the most dangerous enemies for Vampires, especially level 5 Combat Unicorns), Nightmares, Djinns (they are weak themselves, but their damage is high), Ogres or Executioners. For the Tower faction, Riders are dangerous for Vampires; they can knock them down to zero with a charge attack. So, if you're lucky, you might put one to sleep, but you'll definitely take damage from the other. If you're going to play as Vampires, you need to have some support. But with what? Spirits fly slowly, Messengers also aren't very fast, and Dragons can work if you have a lot of them. Speaking of the Tower faction, Riders often attack with luck, or at least, heroes playing as Chaos will get annoyed
