I was chain breeding volt tackle Pichu's trying for a shiny (98 of them and no shiny) and blasting them out into the stratosphere when I received a level 67 shiny Magmar. I sent a couple of shinies out as like a goodwill thing, once I had transferred all of my Pokemon from Gen 5 over (from all generations bumped along) I was feeling generous and sent a lot of good pokemon out, hoping they'd land somewhere they were needed rather than coveted (when I was levelling up between gyms, a pokemon just within badge levels would have been amazing)
