I think the main reason people rely on China/Germany for teams is because they had these ninjas longer th* and have already run teams through the ringer until they find the better teams that end up becoming meta. That's why China has more variety. They are the first to get new ninjas so they actually have to do the work in figuring out what teams work and what teams don't. By the time we get new ninjas, China has already put that ninja through most teams that you can think of. I try to make teams off of what I myself think will work good, but it's hard to ignore good teams that you see in versions months to years ahead of us using while I'm watching space-time videos for entertainment purposes.
