Edit: This video was before Patch 1.18. Before, it didn't have the tumble effect which means backdashing gets punished harder in the corner. The reupload was made because the final music from the original video has a copyright that prevented other countries like Canada from watching. The US shouldn't have a problem though ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MCsrcxApEsY.html ). So, now anyone can watch it. Edit: This is to go over another "what if" Pot did something after a blocked Heat Knuckle ( 6:20 ). If he c.S 2S 236P, backdash is still a valid option since it's possible to OS it albeit tricky. Here's a video to showcase what I mean, sorry for the quality: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LDos60ZK8zI.html
There isn't Throw Protection 'after' Guard Crush, hence why 2:38 isn't possible for us to challenge. But 2:22 and 2:30 are actually two different timings of Pot Buster set at the same distance by the CPU. If you slow it down, you can actually see the first one come out instantly from Kara while the second and third clip you can see a few frames of me doing the motion inputs first. This was recorded by my low end laptop, but I've had matches on my high end PC where I had to delay my input to Pot Bust a sitting opponent. So my conclusion from this is that Garuda Impact can be so plus that they're still on block stun if you Pot Buster ASAP. This isn't the same with Heat Knuckle -> Pot Buster though.
