Been thinking about starting a shiny living dex. Would using cute charm in the gen 4 games to get a good head start be fair? The game is giving me the shinies of its own choosing after all and they'd technically all be legal.
I'd start with platinum then continue with SS and trade my platinum mons over, then do B/B2 and transfer over all my mons from SS, then move on to X and OR and once I've got that I'd trade all my shinies from bank, X/OR and sun to ultra sun and finish up the rest. The only reason to transfer over non shinies from previous gens is if they're not available in SM/USUM so I have something to breed with.
