Kay so...I was breeding my Serperior this morning to try and hatch a female Snivy. It took several tries, but I managed to do it.
Problem is I have at least six Snivy I want to get rid of! There aren't any conditions on what Pokémon you ought to trade, just have one handy so I can pass on a Snivy.
If anybody's interested, PM me with an FC and we can arrange a time. Mine is 1721 2514 4485.
