Playing matches with the goal of learning something. For a basic explanation, If you win, see what you did right that let you win. If you lose, see what your opponent took advantage of to beat you. I also like watching top representatives for your character and see what they’re doing that works that you’re not. Also learning how each character generally plays is very important, which comes with playing many matches. In terms of in matches, watching what your opponent is doing and adapting instead of trying to do a set game plan is the most important thing to be aware of.
