Yuyuko's third noncard is static. Or more accurately, the knives are static and the bubbles are aimed. The high damage types can end it by staying in the center to start, moving to the bottom right as the knives sweep across, and going back up to the center; the card should end before the knives sweep back up again. Since you're using SakuyaA, you could also just hang out in the bottom corner. The knives mostly just come straight down and are readable enough, and you can memorize them if you're dedicated enough.
That said, don't use SakuyaA. Not because she's broken, but because she's one of the worst shottypes in the game. If you want to use Sakuya, use the B type, as she is an absolute beast who lays waste to everything (except for Merlin's opener, which she sucks at)
