The initial setup takes about 3 battle requests on PSS (not battle spot), but yeah the rest is mostly tedious and repetitive. If you're still interested, the route that I would suggest is to save after collecting 5 eggs (1 is the flame body pokemon) then cycle around route 7, hatch them, check their IVs via mixture of kiloude judge, anistar hidden power judge, and battle institute (if needed, altho taking this step is more time consuming), then if you're desired IV spread, nature, gender is there, reset and deposit the egg. Now, once you get a full party of about 5 eggs, hatch them and then look for a battle in PSS (DO NOT SAVE YET) and exit, save battle video, and check TSVs, RESET, DO NOT SAVE.
