As we all know shiny pokemon are a pain in the butt however in the 4th gen there are a few method in capturing/obtaining a shiny pokemon.
Intro: A shiny Pokemon appears 1 out of 8192 meaning that out of every 8191 you can have a chance of getting 1 shiny. Granted this will not happen often since the 1 out of 8191 isn't always true. Basiclly meaning it is unpredictable. So how do we get shiny pokemon with ease.
1.Masuda Method(named after one of the producers) basicly, breed one pokemon with another, however you must have one of them must be from a different nationality(ie: I have a German Beldum breeding with another beldum can up the chance of a shiny(if its not in breed x)
2.Chaining. Use Pokeradar and repels to protect your chain from being broken(this is a pain)
