I have just got the expansion pass for Crown Tundra, and am wondering if it's possible to trade master balls to my main game in order to guarantee I catch legendary pokémon on the Dynamax Adventures.
If I play through the main story on my second cartridge up until I get the master ball, can I trade it to my main cartridge as a held item on a pokémon? Would it also work through Pokémon HOME so I don't have to use another console?
