for one, i will tell you that i dont think youre being patient enough. while your tech skill isnt perfect yet, and you could defnitely improve in areas that contribute to a more fluid mobility layout (plat WDing, keeping your DD tighter towards your opponent, etc.), you are much more mobile and seem to have the greater tech skill than that GW player. honestly, while the potential is in your game, i didnt see all that much potential in the GW player. i dont think he WDed once, i dont think i saw him L cancel, he was very inert and didnt really even DD.. all of his kills and hits he basically got from you running in head first into them. trying playing more patient and calculating with fox. not every single hit has to be followed up immediately by another hit. you can wait for his reaction and punish it, especially in neutral, when you got grabbed a few times for trying to run in with upsmashes. thats honestly the best way to deal with a player of his calibur: just wait for them to do something and then punish it, because you have the speed, and they dont have the skill to deal with it if its applied properly.
