I don't think folks will be able to trade those starters around until the Pokemon Bank opens up in another month or so. No way to transfer them over yet, and I don't think they naturally occur in X & Y so far.

Oh, so I must buy Pokemon Bank on December 27 for 4,99 dollars/year?

well it is possible to get this by breeding on X & Y? It's could be my first time breeding some Pokemon. I saw someone in internet has finished to filling their pokedex.

Also I was thinking about getting Yamask too, it looks cute with Spritzee, but it doesn't looks pretty as Cofagrigus and Aromatisse, then they looks like Dame Edna getting harassed by someone's coffin. I think my Hawlucha looks interested to my Aromatisse.

Yes, but I believe Nintendo is letting everyone have a free month or so of the Bank, so you shoooooould be able to just wait and see if the GTS gets flooded with the old starters.

Like Starfig says... It's impossible to get an Oshawott for now. You have to wait next month for that.

Do you have experience about breeding for fulfilling pokedex? I wonder does those breeding guide works on X & Y?
I think someone has completed their national Pokedex on XY, or are they actually finished Kalos region only?

So hows your sprites going? What was those your new forms what I supposed to draw for your art trade? Entei I remembered, cattle, something big horse... So what else?

Well... Since games were hacked, it was easy to get the national Pokédex. Of course, I'll never hack my game for that.
For now, I only completed the Kalos Pokédex. National Pokédex, I can't do it until we get the Pokémon Bank.

And my sprites... Well, still distracted by many games and videos... And today, a friend visit me. ^^;
However, I'm thinking to draw. But for now, I have a few things I'd like to do first... Like the requests for the Heavy Bottom I accepted for a month now.
Of course, I didn't forget our actual trade. It's just... Well, it's been a while you ask me and... My memory is kinda poor right now... Care to remind me what you asked exactly please? =)
