If you don't mind me commenting on these matches...
Those were really good. You do know the matchup well, but there's a lot of other things you could do to get some three stocks on him.
For example, Use dtilt more. It's practically a
guaranteed tornado setup if you spam it on his shield at max range. Frame-wise, Olimar is unable to punish it with a grab if...
1.) It's not a white
2.) He doesn't powershield it
3.) He doesn't grab on the first following frame.
4.) You're at a good distance
Technically speaking, he has 13 frames to respond out of shield to consecutive dtilts. Olimar's grabbox comes out on frame 11, but it takes more than 2 frames for the pikmin in the grab to reach Meta Knight
if you're spaced. If it's a purple, it'll take even longer. Whites, though, walk really fast so it
may reach you in time. I'm not exactly sure.
Tornado when you start to get close, and if he doesn't immediately grab you, you get a free hit.
Olimar recovering... You know how Olimar drops down below the lip of the stage to come from below to upair you to deter you from edge hogging? Use the invincibility trick and immediately drop down and nair him. You did it once and it worked
fantastically. It went right through his upair and gimped him.
Also, if you're up to it, camping works really well. Get the lead and just camp one side of the stage, nairing pikmin that fly at you and watching out for purples. He'll eventually have to approach. You didn't really need to do it cuz you were beating him so badly, but it's something to consider if you go up against an Olimar player that can preemptively punish the tornado well. Dabuz didn't. You won't be able to rely on the tornado so much against some other players. I'm sure you know that though...
Olimar can pivot his over special to aid his aerial movement. He can also power-shield MT like any other character. The lesson is don't be afraid to perform Mach Tornado, and Olimar's weakness is being off the ground, though I'm not very convinced that it's that bad.
Do you mean b-reverse his whistle (which is neutral-b) to get the sudden change in momentum? It does help a lot though. You're right.
Sorry, that's all I gotta say on Oli-MK. Back to G&W.
