Sworn enemy.

Of course, that's true, but I'm not going to wait for the late game against the Academy, for example! It's better to play a quick game and try to rush them.

Good idea – because you'll have a decent number of units left (at least 4) – and you can use them to protect your archers with someone. But in general, it could happen in the very beginning that you get a week of Titans or Angels, for example... And then you can level up a decent enemy unit, like a Monk, early on.
