Hmm... maybe that's why the included the save feature in Sun/Moon? Then again, it would be a massive blunder if they didn't include cloud saving for their online option, or atleast the ability to export the encrypted saves to a microsd.I interpreted what the person says as trading with yourself, thus needing more than one Switch. It's feasible to get yourself 2 3DSes, hell I have 7, but 2 Switches? Also if I'm not mistaken, the saves are stored in the console, not the cartridge, so without hacking, you best take care of the Switch, it fucks up, your save is gone. I don't know if they fixed that, I just heard it way back during its release.
