I really love the art of this promo. And I always love to know the exact way cards were given out and I think it’s interesting to document this information for the future.
As far as I see there are numerous Infos out there on how the card was exactly obtained (but no place includes all Infos) during the Metamong Project at Lotte park. So I’ll try to summarise as far I understand:
1) Project Metamong was the motto of the Pokémon Town event at Lotte World Mall and World Tower which ran from April 25 to May 18, 2025 in Korea.
1.1) During said event there was a stamp rally taking place wich included 6 locations. To participate in the stamp rally a account with verified phone number was necessary (Korean phone number). Each account could only receive 1 card (it was possible to create multiple accounts with the same number to receive multiple copies). Additionally a Korean ID card was required.
2) Each location of the stamp rally had a QR code to scan. There was an accompanying booklet for the stamp rally but it wasn’t required to complete it.
3) Visitors who scanned at least one of the 6 QR codes of the stamp rally were able to receive the exclusive Metamong Project stamped Ditto promo card at the redemption booth.
Please correct me if I have missed any important info or if I got something wrong.
There is a great bulbapedia article out there which also provides a lot of details but not focusing only on the card and how it was obtained.
