I feel like the swords are just great against M2's giant frame, but I guess he is working with disjoints too. I heavily prefer to play it from the greninja side, that is for sure. Feels less delicate, and you have all kinds of opportunities to land u-smash since he s floaty and large. U-smash and u-throw against his light frame makes him question his preference for low ceilings as well, which is really nice to kind of neutralize the effect of stages, although battlefield platforms are a problem for ninja since it makes shadow ball zoning stronger, and hurts his usmash setup and landing trap game.

I definitely agree that having an unknown character, or a character who's meta isn't understood in your region is a great way to upset a tournament. We have a lot of examples of this, even a major.
Watching umebera, people clearly didn't know their optimal buttons against this surprisingly aggressive (at least once you were in his space, smashes and tilts were flying out all over the place) Olimar.
We set ourselves up for this with 2 stock bo3. You can die to something before you understand your character's best counterplay, since it definitely can take more than 2 stocks to learn a MU on a new level, and once you lose one game and then lose a stock.... You're pretty much done. And if the person has truly labbed their character a lot, you have them adapting to your counterplay throughout the match, e.g. choosing different options on their 50/50 or trap situations, so you adapt but still die to the same thing.
Its yet another reason kill confirms are so great. And its nice that Ninty is spreading the love a little, I always balked at heavyweights who would grab you, and jack **** would happen. Like really, freakin bowser grabs you it should hurt, a lot.
Snake's dthrow was really cool in Brawl for this, in my opinion, at least before abuses were found. More force tech throws would be a reasonable buff for power characters without blowing them up in FFAs. Imagine if DeDeDe could throw you hard forward onto the ground; It'd really make sense with his trap/gordo game (set up your traps on a grounded opponent, or chuck them offstage and set ledge traps with the poor angle they're thrown) and it would have reasonable counter play, especially if you could tech it.
Now im rambling about heavies and game balance. Clearly we just saw that, even in 'optimize focused' meta's, diversity is well and alive. I think this kind of thing encourages diversity, my switch to MK in my Brawl days was basically solidified by seeing him win everything, each win tearing at my belief in my character.
Watching your character take a big tournament is super exciting. Bittersweet, because you might know the stuff he was doing and feel, had he not shined a spotlight, it could be you!
Big rosters are fun.
