It seems insane they would debut a Pokémon in a game and not let you transfer it. It’d be like if Ranger didn’t let you send a Manaphy egg to D/P.
Either that or they redistribute both Meltan and Melmetal again, but I doubt they would do that since they make more money strong arming players into buying LGPE and playing Go.
