The recent version 3.2.2 update for Pokémon HOME added the ability to earn special Pokémon via Mystery Gift by completing specific game Pokédexes. Two new rewards are now available in Pokémon HOME for diligent Trainers who have made it their mission to collect every Pokémon within a region. Now, if you have completed your Hisui Pokédex (from Pokémon Legends: Arceus), you will receive a Shiny Enamorus. If you’ve completed your Sinnoh Pokédex (from Pokémon Brilliant Diamond or Pokémon Shining Pearl), you will receive a Shiny Manaphy.
To receive these Pokémon, you must complete the corresponding Pokédexes in Pokémon HOME, then confirm your completion in the Games tab. If you’ve already completed these Pokédexes, you’re still eligible to receive the Pokémon. Be aware that to receive Mystery Gifts, you must have a linked Nintendo Account, and each Mystery Gift can only be received once per Nintendo Account.
Enjoy earning these special Shiny Pokémon, Trainers!
