Ness vs Cloud is GARBAGE. Ness loses that mu hard. You have Ness who has a pretty meh nuetral, bad disadvantage state, and one of the strongest punish games in the roster versus Cloud who has one of the best neutrals in the game, an OK disadvantage state (it's only bad when he's offstage without limit), and an even stronger punish game than Ness.
Ness gameplan in neutral:
Get a grab. It is his most lucrative tool. From a grab he gets true combos at low percents and sometimes mid precents (other factors must be considered at mid percent like rage, fall speed, etc). He also gets stage control and PKT/aerial juggling at mid percents and a kill throw at late percents.
A competent player isn't just going to let you run up and grab them so you have to condition them to stay grounded and shield. Pivot and shield grabs often require the opponent to flub an approach but if Ness is approaching with a dash grab you have the following options to beat it: you can, roll, spot dodge, throw out an attack like a jab or a tilt, a retreating aerial to whiff punish the grab, a rising aerial to stuff the grab, throw out a dash grab/attack of your own, throw a projectile. Ness must condition his opponent with his normals to get the grab. His aerials have big hitboxes, are disjointed, and can be used to stuff aerial and some grounded approaches. Ness dash attack can stuff grounded approaches, punish some retreating aerials, retreating rolls, and spot dodges. You use a combination of his aerials and dash attack to keep the opponent grounded and in their shield. Once they start shielding you start grabbing. If they try to avoid the grab again then start throwing out Ness normals again. Rinse and repeat.
Back to Ness v Cloud:
Ness gameplan does not work against Cloud. Why? Ness can't keep Cloud on the ground because Ness aerials straight up lose when going head to head with Clouds aerials. This makes it EXTREMELY difficult to condition him and makes neutral very difficult for Ness.
This forces Ness to play a ground game which isn't strong to begin with and is even weaker if you can eliminate his aerial options. This is why he loses to sword characters in general because they all have the tools to do this (some better than others). On the ground all Ness has are his poorly ranged tilts and jab (most if not all of them have less range than Marios, let that sink in). There's also his very poor dash speed and his dash grab which has 6-8 frames more endlag than your average non-tether dash grab. PK Fire, more like PK Lag. Dash attack is Ness' only ground poke with *kinda* low commitment. You can just run around and shield but Cloud does a lot of shield stun and has a normal grab so have fun.
For Ness neutral just amounts to a bunch of hard reads and guess's with few options to work with which will result in him losing neutral quite often. Casinos should make this a game in their venues, that's how much reading and guessing you have to do smh.
Punish Game:
Ness punish game, as strong as it is, isn't strong enough to matter in this MU. In fact, Ness punishes aren't even as strong in this MU as it is in others. On stage if Ness gets in his juggle potential is lessened by stupid **** like Clouds dair, uair, and his range in general. He's heavy so he dies later. Limit can save him offstage as with any of Clouds MU's. PKT juggling is strong if you get him offstage but getting him there is the problem.
Cloud punish game, juggles Ness for free and quite often gets more off of one neutral win than Ness in terms of damage and stage control, Ness nair and uair doesn't help much because swords, can kill Ness earlier than Ness can kill him with LCS, and deadly, low risk edgeguards while in limit.
All in all the one thing that Ness is really good at, punishment, Cloud does it better in this MU
Video You Posted:
The video you posted doesn't really convince me that this MU isn't garbage for Ness. Mr R sd'd in one match, in another match Mr R damn near JV'd him while S1 had a significant lead in that same match, Some stocks S1 got destroyed while Mr R went almost completely untouched.
Other factors: skill gap between Mr R and S1, one player is playing with their main while the other is playing with their secondary. The best we can see of this MU as far as I know is FOW/Shaky vs Leo/Komo/Tweek.
Conclusion:
MU IS TRASH lol
...and M2 v Ness is definitely not even lol M2 wins to say the least, and Ness v Bayo is even at best for Ness. Why? Witch Time
