Is everyone Nuzlocking B2W2 now? I'm playing HG myself. Just beat Morty, nearly losing Dog the Growlithe (2 HP!) and Irwin the Croconaw to that damned Gengar. Columbine the Pidgeotto ended up beating the Gengar and one Haunter with Gust (accidentally Day-cared off Peck). I hate Morty's Gengar now and forever.
On the +++++++side, my first shiny ever - a Koffing from the Burned Tower. So much happy. And on a cartridge!
I just used a Crobat. (Which come to think about it, seems my standard response to a lot of things. Throw a Crobat at it)
