I was breeding for a 0 special attack Dragapult for a doubles Coalossal team and got a shiny Dreepy. So then I decided I might as well pair it with a shiny Coalossal and I only did like 10-12 Rolycoly encounters before getting a shiny.

I conveniently already had another mon that could breed with it that had a 0 special attack IV. With a destiny knot I got a couple that inherited that pretty fast and then started breeding those until I got one with perfect IVs in every stat besides special attack and happened to get a shiny before that happened.
