Which level 1 creature is better?

enemy in the sense of enemy?

No, enemy in the sense of curd cheese.
Well, of course, it's an enemy, who else? :)

Apparently, he forgot about it, or history is silent on the matter.

Apparently, that's the case... :)
It would be interesting to know the outcome of the game...

but how can you forget about the greased fairies – they changed the outcome of the battle (they are usually removed) )))

They remove them, of course, the poor little fairies! But, in my opinion, if you manage to trade 100 Fairies for, say, 2-3 creatures of level 6 or 1-2 monsters of level 7, that's a very profitable trade...
Besides, it's very easy to fight against Greased Fairies at the very beginning of the game, especially in combination with a Grindylow (I like this combination the most). You slow down the enemies and calmly defeat them without any fear of retaliation...
And the hero with Fairies has a very high speed, which allows the Elementalist to regroup quickly or make raids into the enemy's lands. :)
