Me and my friend are doing a shiny only challenge, where we can only use shinys, soft resetting is ok, but sometimes it takes a while to get your shiny guy (it took me 3 weeks of fishing, 9 shiny Remoraids and 1 shiny Qwilfish to find my shiny Horsea) and a decent amount of the time you don't find the guy you want at all.
In the end, the real challenge is dealing with guys with less than perfect/shitty IVs, natures and abilities (at least until 7th Street for the last two), initially filling your team (non-shiny pokemon cannot even be used for fodder in early battles) and just an overall test of patience, on top of the sadistic nightmare test of patience that is Reborn.
