fox should be careful (I could end here but)
with those approaches vs a low % opponent, there is not enough hitstun in fox's aerials. try to connect the aerial closer to the ground, so there'll be more time to run away or to follow up (beginning of game 1 and 2. beginning of game 4 wasn't bad, but it was risky)
this is another case of a risky fox aerial. even though fox hit the opponent, because fox 1. didn't land right after the aerial, or 2. didn't have the opponent in enough hitstun to continue the combo, fox ended up in a bad spot. that fair is a bad fair every day of han solo calendar. don't worry, even isai does those
this should be clear to you, but don't try to be cute at the ledge. I used to do that all day even though I knew I was getting spiked all day. a li'l hard to stop that
samus can ledgegrab from
pretty far, so consider d-tilt as an edgeguard when edgehog isn't possible. if d-smash is working every time, samus needs to recover better. a few times fox tried to edgeguard with a dash attack, that should never work. I'd say that if you play an MU often, you can pick apart the parts of the game for that MU (DI, edgeguard, 'neutral game' / approach, combo, how to avoid respawn inv, etc), select -one-, and improve on that. you said you watch high level play, so pay attention to what choices they do
opportunities for an aerial to dash upsmash like
this one happened a few times. one time you did a shine jab instead, which is fine if you know that you could've killed it with an upsmash instead
my fox chart is somewhere around the forums, but bottom line is every character save DK dies at 91% from the bottom part of DL to a fox upsmash, samus must die at 82 or 85. so, again,
not killing is fine, but if you want to improve and get out of pools, you try to get into the habit of doing the optimal thing and upsmash. I say this 'cause the habit was always a big thing for me. to this day I have to try really hard not to fool around with falcon
samus' fair is
terrible [1] for defending yourself.
risky [2], and
this [3]
basically, samus should've been keeping her back to the opponent, and dairing more instead of fair
this happened a few times, samus would get a dair at high %s, hesitate, and do some random follow up. like in
here. there isn't much secret, when the opponent pops up at around that height (% hint), always be ready for a high-angled f-smash, or even a (pivot) grab. also, if it is going to be an aerial, bair is stronger than nair unless stale
