As I understand it, the "Novice" tournament series is primarily designed to improve the skills of those who want to improve and become competitive in subsequent battles against experienced players. So, based on my own experience, templates that actually improve skills are mirror templates because they teach you to play against an opponent, not against the map. Encourage beginners to use x3dm1.
This does not contradict the introduction of mirror matches.
"Сущность войны — обман. Искусный должен изображать неумелость. При готовности атаковать демонстрируй подчинение. Когда ты близок — кажись далёким, но когда ты очень далеко — притворись, будто ты рядом."
