Finally pulled off the clear. Funnily enough I was intending this to be a practice run to check my performance vs Murasa after spending some time to practice her but stage 4 and 5 went really well overall compared to my more serious runs previously so I just went for it. Entered Byakuren's final card with 3 lives and burnt up all my resources before clearing. Probably could've played it less safe since in practice I've managed to NMBN the card up to phase 5 ocassionally, but nerves got to me.
