Are hard knockdowns counted as groundslams? Because Warc can only fit in two OTG 3C's after EXj214C in the corner.
Warc j214C is a ground slam. That's why you only get 2 3Cs OTG after it.
Edit: Sorry, that's not really a good explanation. The fact that Warc j214C is untechable is not important, the fact that is ground slams is. There are only 3 wall slams, ground bounce, ground slam, OTG relaunch, raw airthrow, (and bound?) attacks that can be used per one valid combo.
Example: If H-VSion does a successful 2A 2C backdash OS, then [IAD OTG j2B 2C]x3 will work, b/c 2C is untechable but does not wall slam, ground bounce, ect. But, Warc j214C ground slams, and so only 2 slots for 3C OTG are left.
