Sadly, the Masuda Method is the only "easy" way of obtaining a Shiny on the 5th Gen. I was also told 1 in 1365.3 is a higher chance then finding a shiny using the Poke Radar. Not only am I lucky getting a Shiny Tepig, but I'm also lucky that it's nature lowers Special Attack and raises Special Defence. Totally perfect on my secondary team.
EDIT: One thing I forgot to mention about the 5th Gen Shinies. Once you encounter one, or even obtain one, you can set it as a default image in the Pokedex. Now when I scroll through my Pokedex, I'll be seeing a shiny Tepig instead of a normal one.
After chaining 40 in the Poke Radar, all Pokemon chained after that has a 1 in 200 chance of being shiny.
Nintendo doesn't want us getting the easy way out, huh?
