The clock was really low when he tried to hang out offstage. Without asking him what his train of thought was in those last minutes, I have to assume that he thought that trying to make it back to the stage would have him risk me hitting him and somehow making a comeback. Sonic's damage output is really bad outside of ASC combos, we all know this, but if I were him I think I would've done the same thing.
He would've won if he had a fully charged fart. Unfortunately for him that's wasn't the case.
I also have no idea what I myself was thinking when I hit him with the Spring projectile. I just wanted to get back onstage because I thought he was going to play some mindgame, and I'm glad I did. If I had used anything but a sex-kicked Nair, a Fair that doesn't connect with the last hit, or a (sourspot?) Bair that would send him towards the blastzone (and risk not outright killing him), he would've DIed that and he would've had enough time assuming he replayed the air-stall strategy. You could see that I was prepared to edgehog him if he did try to get back to the ledge. There was money on the line, I wasn't going to side-taunt him only to have him make it back to the ledge, and have the clock run out with him in the lead.
I am also glad that I didn't decide to run to the edge of the other side of FD and instead stop just short and Fair. I might've ended up using Dash Attack or risk missing a running grab and/or not racking up enough damage to put me in the lead and then have many many other things go wrong in such short time.
And Kuraudo, just for you, I'll challenge SK92 to a MM with his proper main. I am very skeptical I could do any damage, but that is what I also thought when I challenged his Wario, and look what happened.
