The strongest castle in Heroes of Might and Magic IV.

Wait, what do phoenixes have to do with Haven? By the way, it's really debatable who would win in a fight. But I can definitely say one thing: if there are two units of phoenixes, each with one unit, they have a better chance; they will be resurrected twice, and although they will have less health, their damage will be twice as strong. And in general, in my opinion, the coolest faction is Haven. Displacement and teleportation are very helpful during a siege (and teleportation is also useful in the field - you can teleport a unit of archers or spellcasters closer to you); it's especially powerful when one hero displaces enemies from a tower, and another teleports his own units there. And mass slowing is just awesome, especially in all parts of the game; and I'm not even talking about terrible things
