If you want to sacrifice some dmg for simplicity, you can just go directly into the Czarnian Toss after the d2. It still does 28% and I find it to be a little easier and still seems to connect on all jumpins provided you time the toss right.
Just a heads up, the opponent can tech roll out of the jd.3 knockdown if they are airborne. They can roll almost immediately I think, but I'm not sure how long roll lasts so it might still be safe.
If you actually are catching them in the air with either d2 or standing 3, you can hit them with ji3, 1 2 toss MB, b3, ji2 2 1 bf3. I think it breaks into the 40s, and is easier to time IMO.
