Is there anything I need to do in the Pokémon games before it will be no longer possible?
I woke up my sleeping Pokémon; I suggest you do too.
I/You can get BP from battle subway offline by facing the non-Wi-Fi trains.
Downloading the battle video of a Starly beating a Luxray isn’t that consequential.
Mystery gifts have long been over.
What for the Pokémon DS games should I really do or do as much as possible before the server shut down?
example: Get the Rotom Key
