The unofficial but widely respected database Scryfall, which meticulously catalogs every version of every card, lists over 60,000 distinct printings for English-language cards, encompassing all unique artwork and expansion symbol variations
The counter to this argument is that cards like Sage Owl are very popular among players, according to our market data, and thus they can't be as unfun as some of us imagine
Betamon is encounterable in the Tropical Jungle's Mangrove Region (exact map name is TROP04), while Patamon resides near Factorial Town's entrance gate in the Gear Savanna (the map's name is GIAS03)
Finally, material aside, environment matters a lot for long-term safety, so keeping toploaded cards away from high heat, humidity, and direct light will do more for preservation than overthinking the plastic label
We also offer bulk sales of single cards
Lastly, I wanted to give a shout-out for Bilbos Ring
