Spellcards I need help with.
Silent Selene (On and Off, the card seems pretty random to me, but any tips would help)
Fucking Royal Flare.
Cranberry Trap
Four of a kind (I know the patterns, any tips for NOT getting walled?That's pretty much the whole reason I die)
Maze of Motherfucking Love 
Catadiopric
Counter Clock
It's been a while since I've played EoSD Extra, so hopefully I'll get this stuff right.
The blue bullets for Silent Selene follow a set pattern, though they get distorted when Patchouli moves. And I believe the white ones are randomized. The trick is keeping up with Patchouli, and I recommend reading how the blue bullet walls get distorted to do so.
Royal Flare is static, though part way into it can supposedly be hard to slip through. Just curious, what character are you using? MarisaA (and maybe ReimuB?) can cheese this card by staying under Patchouli and only dodging vertically - this ends the card before the harder second wave.
Cranberry Trap has two different waves: one of them goes to the center, the other is aimed at you (sorry, I forget which one is which). For the one that's aimed at you, try to stay in the center anyway, so you have room to dodge downward.
I actually don't remember if any of the bullets in Four of a Kind are aimed. My only advice is to avoid any tight spots altogether, since the metal-fatigue bullets are so broken. If you're playing a powerful enough shottype, it wouldn't hurt to take out one of the clones either.
The gaps in Maze of Love are all static, though you have to be relatively close to Flandre to keep up with them. Other people have also managed this card by micrododging at the bottom, though I'm not sure I recommend it.
The Wiki's description for Catadioptric says it all: the lower-right corner is a relative quiet zone. Do all of your dodging down there. Flandre follows a set pattern regarding where she fires each wave, though I don't think any of the bullets trailing the bubbles are truly static, so you'll still need to do some moving around in the lower-right corner.
Counter Clock's laser wheels also follow a set path, and the smaller bullets Flandre fires are all aimed at you. Don't move too wildly while avoiding the wheels, or the field of smaller bullets might become too convoluted. The third wave is simpler than it looks - start at the bottom, wait for the first part of the lasers to pass, tap left/right once, and start moving upward to avoid the lasers (they converge at the bottom-center). You might want to tap to the side a second time as you move up if the card doesn't end at this point (just judge where the aimed bullets are).
Hope that helps. I'm working off memory here, so I apologize if I got something wrong.
