I have a launch 3DS; it does lag during double battles. I should be getting a New 3DS for either birthday or Christmas; does save data store onto the game card itself or the SD card?

They save to the cartridge.

You people with your Eighteen Type: Null's are so lucky D: Ugh, I only need one extra Type: Null and one extra Cosmoem for my own 'dex goal to be complete for now, and I bet it's gonna be real pain in the arse to do >_<

On another note, I agree with the 'two steps forward, two steps backward, two steps sideways' sentiment some people have. In some ways it feels like a definite step up from Gen VI, in others it feels like a step down, and in others still a completely bizarre swerve to the side.
The story is impeccable, though.

I really enjoyed the story. A massive step upwards from a man with delusions of grandeur running an organization that thinks only the most trendy in the world should live. Meanwhile, all the interesting shit is a footnote that never gets expanded on.
I mean, there are delusions of grandeur here, but it's not as neck breakingly stupid :lol
I really do have a new favorite Pokemon antagonist~

Nevermind. Not gonna add Solgaleo when I get him. Just caught my 6th member- Burastoise the Tortunator.

Just breed a starter, level up a baby to its final stage and put it up for a Type: Null. I guarantee you will get it within half an hour, tops. That's how I got 15 of mine.

Cosmog is a bit more difficult. What I did is put up a Type: Null with leftovers, but since I didn't do that over a dozen times like I did with the Nulls I don't know if that's a consistent going rate. It's an idea if you can get more than one Null through the above method, though.

Anyway. This game is awesome. Story is fantastic. Really enjoying it.

Anyway, I'm up to Solgaleo. I'm trying to catch him in a Beast Ball, so that's a pain.

I've actually caught him twice now, but the first time he had a Mild nature, so I reset. I caught him for the second time as I was writing this (first time after that reset, so not too bad). He's Docile now, which is I guess better.

Ahhh. Don't know if I should be satisfied with this. Neutral nature isn't great, but it's not awful. And that x.01 catch rate isn't helping. But I'm using an Adamant synchronizer so I really would prefer to get him with that nature...

I really wasn't expecting Emergency Exit to work during legendary fights. That's a massive pain in the ass, as Golisopod is my only False Swiper. Ah well. I've pretty much settled on a pattern that puts me at an almost favorable position to catch him.

What to do...

Wow, thanks for the advice! I'm about to head to bed, but that's something to try in the morning! Thank you!

In addition, I snagged Cosmog by putting a Level 7 Litten up on the GTS. Weird.

If it were me, I'd probably go for third time's the charm though? I can't imagine how much of a bitch it must be to work with, though.

Third time was, indeed, the charm! Wasn't as fast as the last time (took a bunch more resets, ran out of balls a couple of times since I only had 10 a friend lent me) but it ended up being not too bad.

Successssss.

And, finally, my team has its sixth member.

Though he's rather overleveled so he probably won't see much use for a bit. That's just how it is with legendaries, though.

It's saved to the cartridge, but you can do a system transfer and move everything from your old 3DS over to your new one anyway :)

Just beat the game. It's damn good, and even though it's got lots of flaws, (SOS battles, pretty easy to overlevel early and midgame, SOS battles, not all megas being available, did I mention SOS battles yet?) I enjoyed almost every moment
Final Team!
Noodles the Incineroar
Cap'n Comet the Minior
Kurri the Tsareena
PancakePower the Snorlax
Spoopychu the Mimikyu
SwiftSamurai the Golisopod
Hope that if STARS is real that they improve on stuff. Also, something I need to mention quickly for people planning on playing competitive, though it's after the champion so spoiler alert
You don't save until after you beat the champion, have a 10 minute cutscene and fight Tapu Koko. However, you can KO it and go to it's cave later, because you can softreset it's nature the second time you fight it. It also has a catch rate of 3
