If I remember correctly, Yuyuko's opener is easier to deal with if you lead her to the right at the start (except on Lunatic, where left is easier). It can be memorized, so just make sure to practice it.
Lost Soul's Village doesn't really have a trick, but since you're using Sakuya A, it should go down pretty quickly anyway. Just make sure you don't forget which side you have to move toward to dodge the laser fan on each wave.
For the second non-spell, start in a corner and slowly stream across the screen, only moving to dodge the bubbles. Sakuya A should end the attack with plenty of time to spare.
Deadly Dance is pretty tricky; it's another streaming attack, but you have to plan when you want to turn around carefully or you'll get trapped. The rings of butterfly bullets look worse than they really are; your main focus should be on the bubbles. Sometimes, the bubbles in a volley are spaced out enough that you can dash between them if you're unfocused, but for your first 1cc, it's probably not worth it. Don't hesitate to bomb if you feel trapped.
The third non-spell is probably Yuyuko's hardest, but once again, Sakuya A makes it quite a bit easier. Stay in the center at the start and then make your way over to a corner when the daggers start closing in on you. You can stay in the corner for quite a while before the daggers start to threaten you again, and Sakuya A will be dealing damage to Yuyuko the whole time, so this shouldn't be too bad.
Flowery Soul is all about planning out a route and repeating it. I prefer to start in the middle, then move up and to the side, and from there, keep going down to the middle and back up on the other side. The blue bullets form safe lanes in places, so make sure to take advantage of them. As long as you don't panic, it should be doable.
The fourth and final non-spell is by far the easiest. Use slight movements to dodge the aimed arrows, keep an eye on the green butterflies, and don't fall asleep.
Repository of Hirokawa is probably Yuyuko's easiest spell card, and Sakuya A only makes it easier. Stay at the side when she fires the butterfly net, then slowly stream to the middle as she fires the aimed butterflies. After she fires the fourth volley of aimed butterflies, make a break for the opposite side of the screen (don't be afraid to unfocus to dash) and repeat from the other side. Other shot types have to work to stay under Yuyuko more during the streaming portion in order to capture the card (as opposed to timing it out), but with Sakuya A, you can ignore Yuyuko's position and still get the capture with plenty of time to spare.
Now we get to the really tough stuff. Sumizome Perfect Blossom is another big streaming attack, but it lasts a really long time and you have to watch out for all the falling cherry blossom bullets, which only grow more numerous with time. I prefer to wait in the middle for Yuyuko to fire the first wave of aimed butterflies, then quickly move to the side and start streaming back toward the middle, but no matter what you do, you're going to have to change directions several times before the card ends. Try to wait until right after Yuyuko has fired an aimed wave at you and then quickly move a fair distance to the side so you'll have room to turn around. Also, note that the aimed waves of butterflies come in two orientations, each mirror images of each other, and they alternate between the two. You'll have to move slightly differently depending on the orientation to get out of the way while still streaming in the same direction, so be mindful of that. For your first 1cc, if you feel trapped, it's always best to play it safe, so don't feel bad if you have to bomb multiple times to get through this. Just remember that after this card comes...
Resurrection Butterfly. All of the difficulty here comes from the red butterfly waves, which you pretty much just have to practice reading until you get a good feel for dodging them. If you're really struggling with that, you can try moving further up the screen and dodging through the waves before they unfold, but it's usually not necessary on Hard or lower. Do be careful not to move too far to the side, or you'll find yourself running into lasers. This is the very last attack in the game, so don't be afraid to bomb every red butterfly wave until you run out of bombs. As you do so, you'll continue to collect cherry, which often means you'll get at least one border during the attack, granting you a free pass on even more waves. If I recall correctly, there are 9 red butterfly waves in all, so if you reach this attack with an extra life and a bomb or two in store, you're in good shape. Just make sure you don't let any bombs go to waste!
