I played a mirror match online yesterday and the opponent did combos beginning with b1 right after exKnives a lot mid screen.
First one was b1, 3, exKnives, b1, 3, 1+3 to restand with the eye laser end. He did exKnives again, which seemed like a good idea, but luckily I blocked and was able to punish with a low start string.
The second one he started with high knee. FWD 4, exKnives, b1, 3, kano ball.
If this meta has been mentioned here I must have missed it. I messed with it in practice and seems slightly space dependent being that you kinda have to be right on top of them with the exKnives to connect the b1, but it reaches further than you might think. b2 works to, but the timing is WAY tighter.
Only played with it a little bit and not yet in the corner. Started to think if I was going to burn the one bar of meter, I would rather do the launcher combo. But if exKnives is thrown to back someone off, it could have a use, so long as the opponent was right on top of you.
Need more feedback maybe.......
