I just found a Chun-li relaunch that works. Here’s what I did:
s:l:, s:m:, s:h:, cr.:h:, :s:, jump, instant stomp kick, pause, j:h:, pause, j:s:, land, s:l:, s:m:, s:h:, cr.:h:, :s:, jump, etc.
It worked in the corner and at mid screen on Spencer and Tron. I haven’t tried it on small characters yet. Just like with the Buktooth bnb, the trick is to be lower than the enemy when you hit them with the j:s: in order to land first and catch them with the st.:l:.
I tried it off of Hoyokusen too, it still worked. I was able to Hoyokusen, launch, drag Spencer back down to the ground, then Hoyokusen again. I’ll see if I can do it off of the Buktooth bnb tomorrow, then I’ll try it off of the new stomp/dash bnb.
Note: I notice that when you launch and enemy and bring them back to the ground, the enemy is still in a “launched” state as long as the combo is going, meaning that any aerial :s: that hits them will cause a “Swoosh” animation and hard knockdown as if it were done during an aerial launch combo. This can allow for some pretty clever combos if you tag out into someone like Dr. Doom.
