So today, I managed to complete Omega Ruby National Pokedex and obtain the Shiny Charm. I am doing a series where I travel to every area in the Hoenn Region and try to get at least one shiny Pokemon from each area. The main method I am using is Horde Encounters and so far, I managed to get a Shiny Zigzagoon in just 23 Hordes and at currently going for Shiny Seedot and am at 190 Horde Encounters.
