Yeah, the trick for when he alters the attack to turn the cards into dice seems to be to parry the cards 2-3 times depending on how long it takes you to parry them. Then when the cards turn to dice, move diagonally into one of 4 corners through the dice, wait for them to go in and then out, then go back into the middle and start parrying the cards and repeating the process. I might upload a no-hit run to demonstrate. I just ran the boss a few times and was satisfied with this run.
I always struggled with that card attack even if I had it down
