Top Tier
Jab 1 - I use this, very much.
Nair - I use Fair and Bair a little more than this. I need to get it down with the tilt stick, then I'd be able to space it appropriately, but I tend to use it to start most of my combos. At low percents, I normally get a grab, Jab combo, Bair, another Nair, or Utilt. Overall, I don't feel I use this enough, mainly on the case of spacing.
Bair - Use this a lot, but not too much as to where I stale it. I like to keep it fresh unless I'm trying to do damage, but I pressure with it a lot.
Bthrow - Def. my instinct whenever I get a grab. After that, I plan a follow up, but it's usually Dash attack if they're at the appropriate percent range.
Pummel - I don't use this at all unless I feel like it, or I'm trying to ground/air release something. I always just feel like throwing immediately for some odd reason I can't explain.
High Tier
Jab 2 - Yes.
Fair - I think I use this too much. I use Jab more, but this is normally my primary move used for spacing. Need to change that.
Jab 3 - Absolutely, I've come to lover ending my jab cancels wit this, but I switch up when the time comes, or I'm bating.
Utilt - Honestly saying this is my primary KO option when I'm on the ground or I can't get a good aerial in. I use it in damage racking occasionally, but not to the point where it's a habit.
Usmash - Reviewing my tourney matches, I feel like I used this way too much, even in situations where it made absolutely no sense. I didn't get punished for how often I was using it, somehow.
Fthrow - Unless I'm near the ledge, I try my best to avoid using this more than Bthrow. Unless I'm going to CG unless a wall or something, I like Bthrow better.
Uair - I think I use this a fair amount. I like to FF it to catch people on the ground, or when they're coming up. It's also fun to catch air dodges.
Mid Tier
Dash Attack - I'm utmost certain I use this too much. My opponents don't normally react in time, and it's a free hit. If it gets shielded, I normally take a grab or something OoS. However, I don't learn from that mistake, and I find myself doing it again, and again, and again. When I mess up the buffer, I'll Dtilt. After the DA, I normally Jab if they're in range.
Aether - I use this primarily for my recovery. I haven't been getting gimped often, since you all helped me with my macthups, so I think I'm fine with this.
Dair - I feel like this is used when it's appropriate. Other than that, I try to catch someone offstage with the walk-off > Dair. I love to use this against an edgeguarding MK.
Dthrow - Don't use this enough. Odder still, I think I use Uthrow more than this.
Ftilt - I use this more or less at inappropriate times. When I get a good bait, it's well worth it. I decimate a lot of ledge recoveries with this.
Low Tier
Fsmash - For me, this is MU dependent. Definitely still low tier for me, but against Ice Climbers, if I get them desynch, I enjoy using this on the false climber to score the KO if they aren't in percent range to die by anything else.
Eruption - I very seldom use this. Try to keep it mainly for a shield break, but I'll dabble with it if I notice a pattern in my opponent's choice of ledge recovery tactics.
Dtilt - I use this at inappropriate times. Judging by my videos, you guys can tell.
Quick Draw - Unless I'm too far out to Aether (which doesn't occur often), I don't have a second jump, or I want to QDC, I don't use this. Period.
Counter - Don't use this often, but when I do, it's well worth it. You may see me do this if I mess up on Quick Draw.
Bottom Tier
Uthrow - Lol I use this y.
Dsmash - I recently got Jab > Dsmash in one of my pool sets. I don't find use for Dsmash often, since I know better options are at my disposal. Cannot unsee.
