I think it would be good for the people who have a koraidon and want a Miraidon but don’t want to give their koraidon away. It doesn’t have to be legends both ends, but under ‘legends’ the ruinous quartet would fall. They can all be traded with shinies as many people need them. You could argue this could be sorted in #trading_sv_pokedex but some people might not want them for the Pokédex, rather for their own battle team or for Tera raids. In other words, permanently. There is no way to trade legends other than for Pokédex completion because every player only gets one. This would be beneficial to those who wish for the legend they don’t have.
