Caught this awhile ago but it was right before the leaks happened and the board imploded, so I haven't gotten the chance to post it.
Ultra Sun breeding with Masuda Method + Shiny Charm. Longest it ever took me to get a shiny through breeding ( about 51 boxes worth of breedjects). Considering my last 2 shinies I bred for took 5 and 10 boxes respectively, I think I've used up all my luck.
