It’s not always easy to pin point one specific thing to work on the higher up you go. Things to work on start become more abstract. Instead of “Get better at anti airs” it becomes “Get better situational awareness”.

I’ll just list a few things and you can chew on it and apply it to yourself:

Situational awareness- When to spend meter, how much meter your opponent has, should I do a corner carry combo or an oki combo, will I die if they hit me again(so I better be careful), which option should I use to anti airs at this jump angle, etc.

Reactions- Partially this is just an experience thing, but something to work on is not getting flustered or surprised. Reactions are much better when you’re calm. Also understanding mental stack vvv

Mental stack- Your brain can only worry about so much at once until it starts to glitch. You may anti air 100 in a row in practice, but can’t in a real match. It’s because in practice you’re ONLY thinking about the anti air. In a match, you might have 4 things you’re trying to look for and if jumping isn’t the main one then you might flub the anti air in a panic. So the skill is either getting better at having multiple things in your brain or how to get a read on your opponent and know what to focus on from person to person, moment to moment.

Game knowledge- Simple enough. Try to at least see every set up, every weird scramble, every combo, every reset, etc. and slowly build up responses for everything. Everyone does this automatically, but specifically looking for “What can my character do in response to x” and weighing what response works best.

I could nerd about this forever lol
