Haven vs. Chaos

I think Haven has a better chance if Chaos doesn't stun the Caretaker. That is, there's a chance to hypnotize the enemy mage or Nightmares, and it's even better with Medusas, as they have a high chance of defeating a hero. The main thing, of course, is to eliminate the hero who casts spells... and Chaos doesn't have spells to remove negative effects, so it can't remove hypnosis or other curses.
