Shiny Mareep obtained! It looks more purple than pink in this version.
Also, someone on an earlier page was asking about passing down hidden abilities via breeding. I may have stumbled across something in regards to that.
I've been trying to Masuda Method myself a shiny Froakie while also working on a 5/6 Froakie for the hell of it. I've managed to get someone's Japanese throwaway Froakie with Protean in Wonder Trade, so I figured, what the hell.
Ditto + JP Protean Froakie Male: Offspring almost always received Protean.
JP Protean Froakie Male + English Torrent Froakie Female: Offspring all received Torrent.
JP Protean Froakie Male + English Protean Froakie Female: Offspring lean towards getting Protean, close to a 70/30 split.
3 boxes full of offspring. No shiny, and the offspring are coming out Decent to Superior with at most 4 IVs when I get the rare Outstanding. More data to come.
Edit:
Also figured something else out.
You know how some abilities in the lead Pokemon affect what you encounter? One of the Mareeps I found have Static, which encourages Electric Type Pokemon to appear at random battles. I K.O. that Mareep so my Position 2 Pokemon (in my case, Scyther) goes out first. I did this in the Lost Hotel to make finding Magnetons easier (got a bunch of Electrodes too, but meh). Gave my Scyther the Thief TM so I could try to steal Metal Coats off the Magnetons. Something to think about if you don't want to use the one you find naturally in game.
Edit 2:
Found someone with a Psychic Safari that has Munna. Anyone want one?
