Wow. In this random play of PCB stage 6, I "captured" the ultimate bullet spam (first time without any slowdown to boot), and captured everything after Butterfly Delusion, meaning I beat the two hardest attacks in the stage at once (fairy spam and Resurrection Butterfly). Now if only I didn't completely screw up and die on each of Yuyuko's first three spell cards I'd have saved the replay.
Also, I managed to defeat lunatic Syou with only one death, due to me capturing her first two spell cards.
And I realized why lunatic Byakuren is SO hard:
4 non-spells
6 spell cards
One of these non-spells are trivial, and another isn't that difficult (her third). None of her spell cards are trivial (though I suppose if I can learn the correct movements Magical Butterfly may very well become trivial someday), one of these 6 is bomb resistant, and another is bomb immune. The bomb resistant one can still be reasonably easily beaten with one bomb. Her last spell card by nature has deaths sneak up on you due to how hard it is to read the openings and judge if you can make an opening.
So assuming you trivialize those two non-spells, use only one bomb on her fifth spell card, and for the sake of convenience ignoring her final spell card, you have 7 attacks that are not trivial and can easily kill you. Each life has two bombs. This is 3 lives this boss will likely choke from you, and that's not factoring in her clip-death happy final spell card, whose last phase makes VoWG look like openings are as plentiful as bullets and can kill you any number of times.
So tl;dr: ARGH.
