Today, after all of that team-grinding, cussing and nail-biting, I've managed to beat Pokémon White 2 and successfully transfer some of my pokémon from Pearl to that game and then over to Pokémon Y. Of course it required me to buy a 3DS for my brother because the transfer wouldn't work with his old DS, so yeah, that was annoying. Was it worth it, though? After I spent quite a bit of time with some of my pokémon from Pearl (and a few of the legendaries from White 2 as well) in Pokémon-Amie, I'm going to say yes, it was definitely worth it. My only gripe is that the capture game that you need to go through for the fourth gen to fifth gen game is just ridiculous. Come on, it was troublesome enough for me and my brother to get another 3DS to get this to work, couldn't they just let you trade them over? It's more annoying than the third-to-fourth gen one. I'm glad that was removed from the newest way of transferring them.
Also, I got a Japanese baby Oshawott via Wonder Trade and I've got an egg I'm waiting to hatch into a Phione. Today's definitely been a good day for me.
Edit: And now I've caught Mewtwo! I've never had one until now!
Edit 2: I also ran into Articuno shortly after the previous edit, and I ran into it again right now. If I can run into it a few more times I'll be able to actually fight and catch it.
Edit 3: Zygarde is now mine. Maybe my brother's right; maybe I am lucky. It would explain how the hell I caught Cobalion in a regular pokéball a few days ago and my current luck with legendary pokémon.
Edit 4: And I've now swept up most of the legendary pokémon I could find in White 2 as well today. I say "most" because I'm not sure if I want Regirock or if I can get any of the other regis.
