Oh forgot to mention, when I finished Pokemon Sword - I finished it by doing the tournament at the end after the DLC Stories.
I cheesed my way through the tournament - easily defeating my opponents with my.....lv 70+ Mewtwo :)
I remember I used to have 6 Mewtwos in Pokemon Blue party - not from trade or cheats but through Pokemon Stadium - I must have replayed Pokemon Red at least 20 times (I was super poor and had no money for games back then because I was early teens and my parents wouldnt buy me anything) and transferred all the legendaries and starters through Pokemon Stadium.
I had a whole box full of Mewtwos....
Anyways, so going through this tournament reminded me of dominating Pokemon Stadium with Mewtwo lol.
