As far as shiny hunts, I'm hunting through Masuda Method for Shiny Frillish, and I have about 120-130 eggs by now.
I just went through the Elite Four a second time on Black, and this time as a serious round. I ended up beating Alder, who I think was really easy.
My brother beat it about 30 minutes before I did, and he used Level 80s. None of mine are there yet.
