Pokémon TCG Pocket's card art has captivated players, but recently discovered details reveal hidden connections to classic Game Boy games. Reddit user asch_win initiated the investigation, highlighting Spearow's card, showcasing Celadon City's Department Store and Route 16, mirroring its in-game location.

This deliberate referencing of iconic locations, confirmed by other users like jteede (who found Diglett near Vermillion City and Haunter near Lavender Town), extends to Supporter cards, further enriching the game's lore.

Many card illustrations depict Pokémon in fantastical settings, some mirroring real-world collectible cards, while others are unique to Pokémon TCG Pocket, adding to the discovery of these Easter eggs. The community is actively searching for more connections, uncovering potential references such as the S.S. Anne on a Gyarados card and a story involving Oddish, Venonat, and Bellsprout near Snorlax's seaside location in FireRed and LeafGreen.

With only one additional booster expansion, Mythical Island, released since October, alongside Wonder Pick events and updates, more cards and hidden references are anticipated. Players are encouraged to explore the existing cards and future releases for further connections.

Currently, a Wonder Pick event features Charmander and Squirtle, and ongoing discussions surround the impact of pack choice on card rarity.
