Yeah this is cool, the NJP-close bomb-b3d4 beats everything but wakeup attack, doing a delayed wakeup against this in any sense forces the overhead low block, only problem is it's a super easy block, but they still have to block it. It's not new persay though as people have been achieving a similar option off 114-close bomb for a while, NJP just seems to be a super easy way of doing it.
My only issue is how obviously you're telegraphing it, as soon as you do that NJP they'll know what's coming, whereas the 114 can go into saw for hkd instead of bomb. If they wakeup you can bait but the smartest thing for them to do is to just delay wakeup and take the easy HTB block. as Cyrax can't do anything from that space, it's not a terrible answer for them as Cyrax meaty pressure is basically non existant without a bomb on the screen, but it does open up meaty grabs etc.
