Ehmm when you guys say that 9-1 is harder than the Ceiling and Satori's remix do you mean StB 9-1 or DS 9-1? Personally i think either of these cards are loads easier than the ceiling.
The StB version is pretty easy. It is likely to fail it a couple of times before capture because of the bullets used for the attack though. DS 9-1 isn't horribly difficult (unless you are like me and didn't know about what the x button could do.) either and much more entertaining than 9-7.
Funny how we all are different.

It's "luck based" simply because we can't handle it yet. The bullets don't wall you at all and the attack varies so much that it can't be micro-memorized. The only "luck" that can be applied is if you're not good enough to consistently dodge it (isn't that true for all difficult attacks anyway?). The attack is tough and great for higher-tier players to test their skills on, but has such a low clear requirement that those of us who can't handle the massive speed and density of the bullets can just luck-trash their way through it and never touch it again. The game isn't filled with these extremely difficult to dodge cards anyway, so I think we can deal with one card that is genuinely too hard for us to pass legitimately (for now).
How boring would the game be if everything was piss easy or memorizable, anyway? Gotta have something to keep you on your toes.
Yeah. That's okay i guess. I remember i thought Apollo 13 was luckshit once too. Maybe one day i'll be able to handle this attack better. I just don't think that will happen any time soon because of Aya's speed. With a slower character i think it would be easier.
EDIT:
I tried the card again. Still one of the hardest scenes in the entire game. Harder than most Lunatic spellcards too. Its something that gets my blood boiling but those Photography games are meant to be harder than the normal games and you got all the attempts you'd ever want anyway so i shouldn't be complaining. I just don't understand how people who doesn't have a problem with this can think of VoWG as anything but a piece of cake as that card is slower and less dense.
