Everyone by now knows that you can superjump at an airborne opponent BEFORE activating, then activate in the air to pass through their attack with [sj.rh x2, sj.strong] and you can juggle them to the corner and paint their fence. The only thing is, C-Groove can block that. So to get around that, after you superjump and activate do [sj.SHORT x3, sj.strong]. One of two things will happen. Either A) they didn’t block all of those hits and they’re already in knockdown state, or B) they blocked all of those hits and it pushed them above you (i.e. you will land first). Here’s how you get around their airblock:
As SOON as you land, SLIDE (c.rh). Since they’re above you, the slide will hit meaty so they can’t airblock it. Since the slide is a knockdown they can be juggled. Do a s.strong and some jumping hits, or s.fierce and scissors to get to the corner and paint their fence.
