I'm still missing a lot of Friend Safari Pokémon, and I've pretty much exhausted all the friend codes I currently have. My FC's 2191-7707-3661, if you're interested. My Friend Safari contains Nuzleaf, Sandile and Liepard, and my Battle Maison team is PorygonZ and Heatran. Of course, feel free to ignore this if we already added each other - though please let me know if you added me but I didn't add you back.
Edit: I also recommend that you add each other for the extra safaris, though naturally that's up to you.
Edit 2: Sweet baby Jesus, I never expected to get this many. Thank you all so much, this really patched a lot of holes in my Pokédex. 536 seen and 470 owned so far, if anyone happens to feel like asking.
Edit 3: Just so we're clear, I'm still taking friend codes. I still have 20 or so slots left, and apparently there's an achievement for filling up the friend list completely.
