-Flowery Soul "Swallowtail Butterfly"
How are you supposed to run away from that...ghost-bomb thing and not get hit? Beats me, and when I'm using a character with a weak bomb I can't just finish the card with that.
PRE-EDIT: So what if other people already talked about it? I feel like putting my 2 cents in, too.
Something that I usually do that gets me killed on that card, despite it being (relatively) simple is trying to rush through the other bullets. Partially ignore the butterfly bomb thingy and focus on weaving through the blue orbs Yuyuko(Or, as I think of her sometimes, Yuyutroll) fires. As long as you don't try to speed through, you should do a bit better.
Also, for the very beginning, start with your character right up near Yuyuko, and inch down as the card begins. That'll make the first butterfly bomb aim right up there, when you can be at the bottom quickly enough. Attached is a S6 replay where, though I wasn't really paying attention to anything else(Hence failing a Practice run of the stage somehow on Sumizome Perfect Blossom...), I capture the card.
