Um, I stay directly beneath her, close enough that Duplex Barrier would hit her, and I then wait until I get murdered, trying to dodge but failing brutally cause I can't figure out what to do. I can't even capture Youmu's version of the card, a card that I class as "Just Bomb Spam it", let alone a harder version of it.
I've honestly only gotten past the card once, I stayed in the lower middle of the screen, and stright down from Chen, I try dodging and I can tell i won't get far as is, I bomb and start moving up to Bomb Spam her past the card, I needed to bomb again just before I got near her, then I get in her face, Bomb once again, but in her face, the card dies, she starts the next one and ends my Extra Stage attempt.
