Read the rules first. Templates are not chosen with the "black" pick. (or rather, the "black" pick will only be in the decisive game of the playoffs). Therefore, imbalances here are not critical.

Could you explain in more detail how this works? I read the Rules, but I don't see how it's possible to play with a reasonably decent template if the opponent (who chooses the three templates) doesn't want to. I, on the contrary, understood from the Rules that "the template is not chosen with the 'black' pick," and because of this, I will definitely have to play on weak templates, and there will be no chance of escaping. It's roughly like playing on the opponent's field in soccer.
