Which units would you like to replace/add?

Humans have peasants, mages have golems, elves have dancers, and the Dungeon faction has minotaurs.

Nope! Peasants bring in the money. I managed to accumulate almost 1000 from dwellings, and that's 1000 gold per day. Golems are great fighters (especially for Razazak). I teleported them into the enemy camp, gave them stone skin, and that's it.

I would remove the zombies and add dead knights, but not the ones on horseback, but the ones on foot in armor with shields.
