I am getting them off Play-Asia and trust me, a Hariyama or Aggron is way more useful than a sabeleye imo.
But in nuzlocke, you can make something out of most Pokemon.
sabeleye is pretty frail though.
Anyhow if you didn't already know I'm nuzlocking white
I hope I can get my hands on one of these as the can't be taken down in a single hit
