It might be worth noting that after a 5D-D chain pull on block I think he can space a J.B well enough to hit Lambda while keeping himself out of the way of 6A.
Also if you normal block a 5D-D chain pull I think he can mash J.A and it hits before you can get a 6A out in certain circumstances.
And if the haz really knows their stuff they can bait someone who's auto-pioting 6A by canceling the 5D-D chain pull with a normal while zooming towards you, which causes Haz to land on the ground just within his 3C range. You do 6A, he gets 3C CH. lol
You gotta react to where he's pulling himself from, what height, what chain pull type. His approaches from the air are even more diverse.
Try messing around with it in training and see what scenario's let you 6A him out of things and where you get hit too early or miss. And then it's down to reacting and punishing it.
(I'm sorta new btw lol I hope Hexa will vouch that I'm not talking nonsese )
