Which level 1 monster do you like the most in Heroes of Might and Magic V?

Let's imagine. We load a mission. We need to build a castle, raise creatures, and level up the hero. We take the hero and, with a small army, wander around the castle. We level up a bit. We don't get into fights. After a week, we buy some skeletons and go to fight neutral creatures. Let's say, fairies, gremlins, gnomes, etc. Note that there will be no more than 60 skeletons. And who will win?
