first of all, nice champ combo.
your fox is good. You know what to do in certain situations. Still, you were pretty predictable that I was surprise the kirby player didn't caught on. I caught on since the first match haha.
All of your kill was up smash. I know it's fox's best killing move, but that kirby didn't even realize it or something. Try to mix it up more. It's not hard to shield or predict an up smash from fox since it's not as effective as before and a good player know when it's coming.
Secondly, play on smaller stages. You are playing a cat and mouse game with fox. Which is good since he's fast. Although, you were doing it on final d and smashville. If you are going to a tourney then don't expect to always fight there. Try to do ur little mind game on like battlefield and you will know that it's a lot harder. I'm not saying what you are doing is not effective, but you need to try doing it on a much smaller stage where they don't need to run for a while to get to you.
Lastly, even though u r moving around a lot, you missed a lot of opening opportunity.
hope this help. You can take this for whatever you want.
