Please do! I'm a Ganon main, I lived in an apartment with a few other competitive players. Haven't played since I graduated. Marth was the bane of my existence. I used to main Ness, and Mofo (of this legendary match ) actually lived near my school, so I got to learn some cool tricks from him. I've toyed with the idea of having a non fraudulent main, but life is too short to learn multishining.
You linked to the Reign of Kindo video, which tripped me up. I don't play much anymore, but so many of my friends from disparate circles play. Both of my little brothers are also ranked in PM, I can't even come close to touching them.
I main Kirby in PM too! Threefish and Ren, I think they're ranked like 4 and 5 in Alaska for PM. We also just had Umbreon stay here for a summer, he helped developed some of the character movesets in PM. He dominated PM his entire stay here, he knows how to gimp with a lot of characters, but that's kind of expected, haha.
