I was messing around trying to find a relyable and fast set up for this wcs, the idea is that you want to barely avoid the corner and you want to do so with as much vertical speed as possible. For this setup you want to dash from basically anywhere on this platform by reacting to the explosion sound and then hold left. As long as you dont have lr set up (no reason why you should) you will cling to the wall briefly (i found this delay to be pretty important, so if for whatever reason you werent getting it, now you know why). Once you land on the platform you simply have to buffer a full jump and dash roughly once your head lines up with this thing on the background.
