Hey there, stopping by your profile (I didn't want to send a PM because it was getting cluttered) to let you know that I just hatched the correct Mareep AND Litwick. Furthermore, the Litwick is 6IVs flawless. I've been pretty lucky today haha
That being said, I'll be ready to trade whenever you finish with Fletchling and Chespin. I'm in no rush, so take your time if you need to.
