So I'm not sure if this was possible prepatch, but check this out. It's very proof-of-concepty right now, but I'm looking to optimize and get better setups. Point is that it can be done.
I'm also looking at his restand potential with ex icicle + db2 (you can see me f it up at the end of the first video), but it was super finnicky before the patch and now even more so...I think. But if these two things can be hashed out I think he'd jump to brokenness pretty quick :V
This is a prepatch video i took:
What's really interesting is that it would also restand off a juggle. Haven't checked yet if it works post-patch
Edit: so I played around with the restand thing a little more and it looks like it no longer works off of juggles. It's still works on the ground, but it seems like nrs reduced the gravity (whaaaa) after ex db3 such that you can't get the restanding hit at the right time anymore. The only way I've been able to get the gravity high enough is by putting the opponent into a second lvl2 bubble, but in that state it's impossible to set up an ex icicle. I wish they'd allow an ex db3 after they get frozen by a lvl 2 trait, but w/e.
