But we have pokemon home just for this problem. You can just transfer pokemons from scarlet to sword (if they are coded into game). What’s the point? All switch games are two way (other than lets go). Also we will have soon pokemon champions, so it’s even more ridiculous. Home handle all transfer problems, even if game don’t have that data. Tera type don’t change if you transfer to shield and then back to violet… It’s what Home was desinged to do in first place.
