Unknown should stream a let's play with me. For SSBM.
Really, I just mean we should play Melee because IMPULSE is coming up.
Aesir, just get used to moving from B to the jump buttons more effectively. You're still new so if you find another button input works better (if you're X right now, maybe try Y) it shouldn't be unreasonably hard to switch. Consider the standard claw - I love it for my FCs, ledgehop bairs, up smashes, and unlike Javi's I still have a finger near the Z button (so grabbing isn't a chore).
It's also possible you're just having bad days. Though you should still practice because bad days are a reflection of technical inconsistency (which can only be fixed by playing and figuring out better ways or doing your inputs or just building the muscle memory itself).
Also, remember to practice your stuff hitting people and not hitting people. The timings are different. Kill yourself periodically to refresh your moves (fresh vs stale can be really, really noticeable on stuff like bairs).
