Some cool anti-wake up combos in here, and I never thought about doing d2 in orb combos.
I was working on ending corner combos with orb and then doing f44 and on block confirming into dragon's roar, which jails into the orb exploding, allowing for a free follow up that only armour beats, so a pseudo-blockstring. Then on hit confirm into bicycle kicks, orb explodes and you get a big combo into the same set up, but I found that delayed getup fucked the setup. I tried a combination of strings and timings but couldn't get anything as good as the f44 db2 block string. Have you looked into anything like that?
