The way for trainers to transfer Pokemon has evolved again with Pokemon Home. As Nintendo's latest feature for the series, fans all over the world can now move their Pokemon between the most recent games in the franchise. Using cloud-based services, there are also be multiple ways to trade Pokemon with friends and other trainers globally.
Pokemon Home is the most recent form of communication between generations like the Time Capsule, Pal Park, and Pokemon Bank from past games. With their Nintendo account, trainers can move Pokemon from the latest games into Pokemon Home or even shuffle them around into other compatible entries. Since launch, its service is confirmed to be compatible with the latest titles including Pokemon Let's Go Pikachu/Eevee, Pokemon Sword and Shield, and even Pokemon GO in a future update. Using software on mobile devices, trainers will be able to trade Pokemon with up to four different methods.
Wonder Box
This method allows trainers to trade their Pokemon for a random one across the world. Putting a Pokemon into one of the open spots will eventually exchange it with the contents of another trainer's Wonder Box, there are no take backs once this happens. Note that there will only be three open spots for the free version compared to premium users who get ten spots. Furthermore, the Wonder Box is active even when trainers aren't using the Pokemon Home app.
GTS
GTS lets trainers search for desired Pokemon while specifying what they will trade in return. From there, the system will pair up individuals with the right requirements on both sides. After details such as level and gender look good, trainers can complete the trade by offering their Pokemon desired by the other party. Free users can only put one Pokemon into the GTS while the premium version lets up to three Pokemon at a time.
Room Trade
If trainers want a more social experience while trading, they can take part in a room trade. These trade rooms cap at 20 trainers and involve exchanging Pokemon among whoever joins. With only two people the trade is straightforward, but the result becomes increasingly random as more trainers gain access to the room. Note that free users can only join rooms, creating one requires the premium version of Pokemon Home.
Friend Trade
Finally, trainers have the option to trade with any friends made on Pokemon Home. If they don't have any yet, there is an "Add Friend" feature from the main menu that only requires the friend code from their Pokemon Home profile. After the friendship is confirmed, trainers and their friends can then trade Pokemon barring restrictions similar to Pokemon GO such as being age 16 or older.
Pokemon Home is now available for the Nintendo Switch, iOS, and Android.
