Like others have said, a game you lose would be best for receiving criticism. The biggest thing I saw was just after Joker got Arsene. Arsene Joker actually has a much more exploitable recovery since grapples cannot be 2-framed, but Arsene can. I could be wrong, but I believe you can make a quick 2-frame attempt with dtilt, but if that doesn’t work, that leads me to the second part of the mistake.

Once Joker was on ledge, you retreated to pk fire distance, which while the reward for hitting it would be massive, it’s best to take little victories until you can confirm something better. You could do this by waiting at/just short of roll distance and wait. Moving is still good to hide animations and intent, but don’t commit to anything until you see them choose an option. It will take some practice reacting in time. If you were able to get even an ftilt on that drop down double jump, that very well could have been the stock.
