I figured he was just a regular annoying youtuber. Sorry for drudging up the drama lol
On team building, I too like to try using all new Pokemon for the first run. Even for remakes I'll try to recreate the experience. In XY, I think I played through 3 times with teams of new Pokemon before using old favorites and thematic teams. I can see myself song that this generation as well since there are a lot of designs I really like. Alolan forms are an exception since theyre practically new Pokemon.
