According to the Pokedex, litleo can only only be found in route 22. My shiny Zoroark hasn't got exactly the best stats either, even though it was bred. I'm keeping it anyway for the sake of collection. I tried chaining but I was really bad at it. I heard two shiny patches, and each time i wasn't paying attention and i chose the wrong patch. My shiny bergmite,pancham and machoke were all found by accident in friend safari. I think the chances of finding a shiny in friend safari are close to that of masuda method, maybe a little bit more or less. For me it's possible to breed 5IV shiny pokemon since I have shiny 6IV Korean ditto given to me. If I get another english 6IV pokemon, I will get a 5IV pokemon with the right nature every time with a chance of getting a shiny! But I'm only going to that competitively. I really wish I got that shiny charmander later in the breeding process for a competitive pokemon, because I was teaching it Dragon Dance and Outrage.
