As Gen 7 for 3DS has come to an end, I'm slightly more comfortable releasing this.
This is only for users who want to experience receiving a fake card (for fun)
Do note that:
1. Wonder cards edited/made would become illegal in nature
2. I don't recommend ever going online on a save that has wonder cards made from this
3. Do not contribute faked/edited events IN ANY WAY to us.
4. Do not ask for updates (unless it is for critical bug fixing)
If you need to report bugs, support thread:

This event was initially distributed by having players use the Nintendo Zone app at 7SPOTs, in order to grab a serial code,
to commemorate the upcoming release of Movie 20: Pokemon I Choose You in Japan.
The last day to receive a code is August 20th, and the code expiry date is August 28th.
A second distribution was held at Pokemon Centers in Japan via Local Wireless.
Charizard, Piplup or Lucario were distributed together, and only one of three can be received once per day, and players can only receive one of each per game.

Based on the NTR dump contributed of the Local Wireless version, dating Aug 23rd 2017,
the Distribution text of the Charizard differs from the Serial Code version.
It's unknown why this change was made, and whether it'll be changed.
(functionally speaking, Pokemon data received isn't affected by this)

Here are two saves to the game My Pokémon Ranch (non Japanese versions).

The file My Pokemon Ranch.rar is from @thaleskpl (submitted to digiex), where the Mew and Phione are ready to be redeemed.
All the player has do to is to send an egg and Leafeon over to complete the trade.
The file my poke ranch new save.rar is from @yeison_diaz (submitted to here), where the Mew and Phione and a few others has already been redeemed, but it appears there's some trades from Hayley that may still be available.

Thanks to the research into the save structure done by @suloku, the tradable Pokémon have already been extracted and added to the existing entries in our In-Game Series > Pokémon Ranch area.
