>>58947000We have no clue currently, but they could either do it through HOME with the challenge system or the mystery gift feature. Crystal VC didn't have this because Bank integration was far less in-depth. The way I see it is that if they had to make their own specific application for this, there should be a way where HOME can read the save when you launch it from the Switch application, then once you do that, you can go over to the phone version and use the mystery gift.
They could also do amiibo since they have their own app outside of NSO that may not even support NFC scanning. I was thinking this would be cool for both mystery gifts (Lugia&Ho-oh and Deoxys figures) and then replicate the eReader cards for that functionality, too. For a download only game like this however, I feel that might be too much work.
Not related but I was thinking that they could also use HOME to do a Egg lottery system where Bridgette from Bank/Box RS shows up and takes your HOME points for a random egg, then puts it into an Egg box in HOME that can only be deposited into FrLg and it then has a chance to hatch into a Johto/Hoenn Pokemon not typically available. HOME compatibility has the chance to actually be pretty cool between that and the aforementioned challenges system. But with GameFreak being all about missed opportunities, I can see them doing the bare minimum.
