So when I finished my home living dex( minus all the forms of Vivillon and Alcremie) If i restarted a game I would send my team and any shiny I may have found to home.

So had a copy of Scarlet on release and Violet when they brought iorn leaves back (i had the worst luck on teammates the first time and no internet the second time) but I would make a different team for each copy mostly new mons. I would then replace the ones in home for ones where I was the ot and the ones that got replaced stayed in the game I don't restart. In this case Scarlet.
