If you take a Chesnaught, Delphox, Greninja, or Floette (Eternal Flower) you obtained in 「Pokémon LEGENDS Z-A」, deposit it in 「Pokémon HOME」, and then send that Pokémon on an expedition to 「Pokémon Champions」, you can obtain the corresponding Mega Stone from the 「Mailbox」 in 「Pokémon Champions」.
※Sending Chesnaught on an expedition from 「Pokémon HOME」 to 「Pokémon Champions」 gets you Chesnaughtite; sending Delphox gets you Delphoxite; sending Greninja gets you Greninjite; and sending Floette (Eternal Flower) gets you Floettite.
※Chesnaught, Delphox, Greninja, or Floette (Eternal Flower) that were made your partner in a game other than 「Pokémon LEGENDS Z-A」 will not earn you a Mega Stone even if sent on an expedition.
※Chesnaughtite, Delphoxite, Greninjite, and Floettite can be received on both the Nintendo Switch version and the smartphone version.
※The Mega Stones obtainable through this campaign may be unlocked in the in-game shop, among other places, at a later date.
