I'd say just practice till you know the pattern for the fairies, as far as i know there's no safespot but just pure dodging. For "Silent Silene" my advice, personally would to stay half way across the screen (personally i don't like playing against that card for long periods of time, gets tiring in a way, thus dying) and work your way around and because its closer to patchy, her life will decline further, than shooting from the bottom of the screen.
For Royal Flare, gosh, if you really wanted to capture it go watch some people from youtube or even MoTK's scoring board and have a look around capturing it. but i'm in no position to capture, takes time so i'd bomb it and bomb the next spell too about half way down her life (depending on what shot type you use), lazyness ftw.
Then for Flandre, her spells 1st - 4th shouldn't be a problem.
I'd say for this, go watch someone else clear it on youtube or MotK, i managed to clear it again just to show you,

Cadioptric, can be seen in my reply, for the first wave, go to
near the bottom left, after tat wave, then to the near bottom right, and dodge appropriately, then should be the bottom middle for that wave, by then i think you should have captured that card.
