I'm desperately trying to reconstruct several of my regional teams before XY's release, which is a tedious task, because I am searching for team members with appropriate natures and at least a rating of "Relatively Superior" from the stats judge (IVs must total 121 or higher). So far I have scrapped together 3 members of my Johto team (Bayleef, Mareep, Pineco) and I am currently breeding for an Adamant Snubbull (because they are too rare to search for in the wild). My other team in progess is for Sinnoh, and so far I've only have my Piplup. The other 5 I will breed from members of my original Sinnoh team who unfortunately have horrible stats. As for the other 3 regions, my Unova team is complete on my Black 2 version and I will remake Kanto and Hoenn using the Bulbasaur and Torchic in XY.
So yeah, I have my hands full.
