Shinies become pretty lame when the only ones you find are of crappy species'. A shiny Bidoof was the first shiny I caught... lame. I bumped into quite a lot afterwards. A shiny Shinx (critical hit, you can guess what happened), Shellos (same as Shinx), Geodude (Self-Destruct...), Roselia x2 (caught both, thankfully), Makuhita (critical hit KO'd as well, but I wasn't planning on catching it anyways :P).
