Ask me for any Pokémon you're curious about and I'll try to get them for you if I have them (in Egg form too!). I will try not to go all out on Egg Moves because it's the first run of the game, but I may still have one or two showing up intended or otherwise.
What would I want back? Something not from Black original version. Marill and Mareep from Floccesy Ranch, or Elekid from Virbank Complex are all White exclusive options from back then that appear early. Magnemite is also an option from Virbank Complex. So based on this, choose a batch in order of importance and I'll try to get you babies.
(If I find this evening when checking that I have any of these, I'll let you know so we can exclude them. The trade offer stands as you come across other new Unova entries I may not have.)
