A seemingly useless Magikarp Pokémon card from the Paldea Evolved set has experienced a significant price increase of over $100 in two weeks, driven by its artwork and rarity, despite its poor gameplay stats, highlighting how collector interest often values artistic and rarity factors over in-game utility.
Only three Pokémon, Magikarp, Psyduck, and Magnemite, are catchable in at least one of every mainline pair of Pokémon games, while Pikachu is not. The reason for Pikachu's absence in some games is due to the controversy surrounding the release of Black and White, which only featured brand-new Pokémon. Magikarp is obtainable through a salesman on Marvelous Bridge in Black and White, while Psyduck and its evolution Golduck are available in Unova. Magnemite can be found in White Forest in White-exclusive locations.
