I thought an abnormally high win streak means win trading too before but it turned out to be false. When I look at the current champion leaderboard, multiple zeakio accounts have abnormally high win streaks. This is not just this season. They had an extremely high win streak in previous seasons as well. I checked their battle history and they are battling with normal players.

I quickly learned that they're just extremely good at this game.

Did anyone even check ueyuey, shnapoon, halfblue's youtube channels? I know they are speaking Japanese, so you might not understand but you can at least tell they are playing the game legitimately.
