Shimmy into whiff punish works best for me on well spaced d1, b1 and f3. If you hit any of these buttons people are eager to hit a poke if you conditioned them with a few throws. On the tip of those moves most d1/d3s whiff opening them up to b14 confirms.
I dunno if it's an online thing but b1 works kinda well as a stagger especially from tip range because on recovery Scorpion moves his body back. I know it's generally unsafe and you can get called out on it, but I barely ever experience that.
Shoutouts to 21 as it's + on block and has enough pushback to allow you to either walk back or just poke into more + frames.
