LOL, well getting shiny legendaries is a bit harder, i have a friend on wifi chat that can exlain it whenever he is on but he isnt on often, and im likely to be on even less now that school just started up again -.-
like i tell every1 its hard to explain, its like a monkey see monkey do sort of thing, lol.
getting shiny legendaries with RNG is alot more dedication than hatching shiny pokemon :/ i wish it were as easy. first time i got shiny rayquaza with RNG it killed itself with outrage, i was ticked because the delay was hard to hit and i had to make 363 elm calls lol. but i finally got it, at 4 am the next day.
first u would go to time finder go to the capture tab put in the ivs and nature u want, run a search, the search will take a while, once u find that copy that to clipboard the synchronize ability helps out alot btw, thats about all that i can explain lol the rest i even get help on.
