What nature are you looking for in the Squirtle, or will you take any? Does HA matter? Do you want Aura Sphere and Dragon Pulse? I have a friend safari for them and I'm willing to breed your Dive Ball squirt. Same goes for the 'Mander. It's likely to take a fair amount of time for either as I'm trying to play through Black 2 before Bank comes out, but I want breeders for the Kanto starters anyway, might as well put 'em in the balls you're looking for and snag a few additions to my own collection.
What would you be willing to trade for them? Would you call a Female+Male Fletchling set for your desired Female Adamant 'mander a fair trade? And what about a female Eevee for the female Squirt? They'll be in your desired balls, but it may be a few weeks before I have them for you, like I said I'm glued to a Black 2 Nuzlocke for the time being. I just want to know what you'll part with before I start breeding them. Offer up a sick deal and I'll put my Black 2 on hold and make it <1 week if possible, though. I don't have a 6-IV Ditto so it sometimes takes me days to get past that 4-IV plateau.
