Thanks a ton for the tips I will definitely work on these things and I have started to notice them in my play as well. Although I do have a few questions:
1. What do you mean smoother/fluid play, smoother movement? I like to mess around with other characters a lot, do you think that would make me less fluid with mario?
2. What should I do about shield grabbing, I'm not gonna lie I think this is my weakest point, I feel Like I get shield grabbed a ton? I have practiced doing cross-up aerials on shield and have tried practice spacing, but not sure exactly what I should do to improve here.
3. Ok now with neutral I live in a small scene with not many good players, so how should I practice neutral? It seems difficult if I am not playing against players who have a strong neutral game, or is watching matches my best bet here for learning?
Fluidity, in my opinion, comes with playing the game a lot. It might come faster if you focus on a character, but I wouldn't say that's mandatory for playing more fluidly. I would hazard though, that if you want to improve at the game at the fastest pace you can, sticking it out with one character is the way to go. What I meant specifically though, and it's something that I'm personally working on as well, is knowing what you want to do after what you're currently doing. To explain with a situation, say you are Uthrow chaingrabbing Fox on battlefield. He DI's onto a platform and techs. Good fluidity, would be understanding that the Fox is going to tech on the platform, and reacting/ reading his tech and continuing your aggression.
It honestly just boils down to having a plan though. Say your opponent dash attacks the back of your shield. You can't shield grab, so instead you Nair out of shield. Instead of just breaking his aggression though, you push your advantage, and go for a tech chase, off of your Nair. Keeping this fluidity up, and having some sort of constant, competent, action, will keep your opponent thinking on their feet, as the game will become a constant series of interactions, rather than interactions with space and time in between them. A good player to watch for this is n0ne, because he's got a hyper aggressive game plan. Whenever the opponent techs he reacts or reads, and goes for something. If he's walling the opponent out with Bair's and one connects, he tries to get a grab or further combo off of it.
I think that getting shield grabbed is a good show of how tight your offensive game is. Mario has a lot of methods of being aggressive without risking getting shield grabbed, like cross up Uair, late Uair into jabs, well spaced Fair, or fadeaway Fair/ Uair, though spaced aerials will only protect you from shield grab against characters who don't have gross grab ranges, like Marth. Honestly, you could benefit from being more grounded. Something important to understand about smash, is leaving the ground takes away some of your options, and makes your mobility much less accessible. Spending more time, DD'ing, poking with Ftilt, applying some jab pressure, and in general flexing with
grounded options will make your game tighter.
You can sort of get a feel for neutral without even playing against the best of players, you'll just have to fine tune those options once you play against people with tighter games. In general the neutral consists of safe options, like hitting with the tip of Ftilt, jab strings, and crossed up aerials. You can play a more aggressive, defensive, or poking based neutral, or any mix of those. It's super personal preference. I'd say watch A Rookie or KoopaTroopa for neutral. They both have solid neutral games.
