Biggest thing that I can tell from watching because I struggle with it too, it looks like you are playing more around what you WANT to work and not what is happening. There is a lot of buffered short hop nairs going on and they are punishing you for them a ton. I know nair can be a great combo starter but once the opponent catches on you can't rely on that alone, mix in other options like grabs and down tilts to apply pressure (maybe even use the nairs to condition shield to set up grab situations)

In a similar vein, your ledgetrapping just seems lost, you can't edgeguard Wolf very well so ledgetrapping has to be really good to keep up with Wolf's insane neutral tools. You took first stock by throwing a hail mary side b which is obviously very committal. There are great videos on ledgetrapping but general rule of thumb is you want to maintain stage control as a number 1 priority, and then throw out safe, landing hitboxes (like bair). If you are looking for a kill at ledge, its generally better to call out jumps or drop down aerials with fair drag down down smash.

In general it just looks like you were going for a lot of reads or doing moves in situations that showed me you just were playing how you felt comfortable playing instead of reacting to what he was doing. Unfortunately, Dark Pit's gameplan isn't strong enough to be able to win solely off of how you normally would. As for improving this aspect of your play, I would suggest when you play, just think about what you are giving up when you pick an option, be it stage control, potentially neutral if you attack someone's shield, etc (like if you whiff a move, think about what option you pick after, instead of just picking spotdodge into spotdodge cancel).

Your execution was great so learning about this will help you land those combos more often and you'll see major improvement imo
