yea i think its safe to say that you were in control until the end. Your first kill was impressive use of wing refresh to chase, and your 2nd kill was some creative use of the ledge.
I feel like you are an aerial genius. You have great control of pit's aerials, and seem to have an exceedingly easy time getting them off, this part of your game is very solid. I wont say that you arent adept at ground fighting, but more along the lines that you sort of neglect it altogether. I noticed sometimes where a ground attack would have sufficed, but you used bluff aerials to draw the opponent into a real one instead. sometimes in this situation it would be better to bluff the aerials, since your good at doing so without leaving oppenings, and draw the opponent into a jab combo or d-tilt. These arguable have more follow-ups then landing pretty much any aerial. I didnt see you use these to excellent ground moves until the 3rd stock (actually, i dont think i saw a single d-tilt)
I believe that wario's game revolves around abuse of priority, which your opponent used well, and spot/air dodges. Your opponent did not abuse wario's ridiculous spot and air dodges so i feel like you should have been extra aggressive because of this. The best warios that i played were great at using these dodges and punishing missed attacks, against this type of player you would want to draw out the dodge and punish accordingly. This player didnt do the excessive dodging so i feel like he would have submitted to pit's potentially endless strings of sword flurry... i guess im saying you were a little too cautious in fighting him, and to conscious of your spacing. I recommend getting in there with a SH-Nair (its the move discussion this week if you need reminders of its good uses) and beginning an infinite jab combo, cut it short early and use a d-tilt to pop him in the air (wingdash first if he DIs away). From here you should be able to safelt get off an aerial or two then slow the pace down again. Dont let wario be in control or else he will out-prioritize everything you throw at him. Show him no quarter, dont let him get his feet grounded, keep the pressure high, and the combos long. Also couldnt hurt to use a little more arrows, but this was probably because of the yoshi level i assume. Hope this helped i like your pit alot, kown.
