Well, with the leaks, I can finally know what are the possibilities; they're somewhat underwhelming, compared to the cornucopia of options I had in XY, but, it's enough to make a team, and there's a few pokemon I love but never get to use, so maybe they can get a chance this time.
Primarina - Of course I'm using her. She's the best starter in twenty years, too bad they still didn't fix the gender ratio.
Ninetales - I don't even need to justify this one; favorite, best pokemon ever, graceful, beautiful, kind, et cetera. Too bad she's more than likely a late-game capture.
Lurantis - She was against Tsareena and Lilligant, but one isn't in the game, and the other one is more or less the same, so I'll pick striped sixties' pants over thigh-high boots.
Mismagius - She's usually on my main team, so of course she gets a place, also, she has the best coverage of the group.
Glaceon - Same thing; hopefully she'll evolve with Ice Stone now.
The last spot is... complicated; Lanturn seems the smartest choice, but I used her in Y already, and also want to use Ribombee and Tsareena, maybe Pheromosa too, and so many pokemon I never use because there are stronger options; Corsola, Ariados, Masquerain, Dragonair... too bad my team is already very bad, type-wise, and none of them help much with that.
But, it's not like I care too much about type balance anyway.
