A little bit late response but what the hell....
As i recall, the combo goes like this:
236-k- [k],S,2D(-k-),214K,41236S...etc
I'm not 100% sure, but it's not important..
I have found much easier way
236-k-,K,S,2D+K,214K,41236S...etc
For the normal moves D has more priority than K, so the 2D will come out. For the shadow moves, K has more priority than D, so the Mawaru will come out. And obviously, since you are in the middle of the combo, you won't burst...
With this metod it can be learned in no time, it's very easy and screw up possibility is very low.
