The trick to the third spell card: Don't move. I can't say the lasers are aimed away from you, but this spell card's trick is to trick you into trying to read the lasers, when in reality all you have to do is dodge them as they come and you'll find yourself dying a lot less. As for Unzan's incoming fists, keep in mind that these bullets have a safespot at the bottom where his knuckles don't meet. For the first two fist waves, you should misdirect them so you can move down and use this safespot, then move up on the third wave where Unzan's hitbox will soon run out of life.
Also, I think I may have figured out how to make Dipper Creeping Close (Murasa's survival card) as simple as possible on hard mode. That's something I guess.
