151 is one of the clearest examples of a set built almost entirely on nostalgia, and it worked exactly as intended.
Every original Pokémon, one set
The set takes its name from the original 151 Pokémon introduced in the first generation of games, giving each one a modern card within a single release — something that hadn't been done in one place before.
Why it hit so hard with collectors
For anyone who grew up with the original games, 151 offered a complete, achievable collecting goal built entirely around characters they already knew, which drove demand well beyond what a typical new-Pokémon set usually sees.
Modern mechanics, classic roster
Despite the nostalgic subject matter, 151 uses the current Scarlet & Violet era card frame, rarity system and mechanics — it's a modern set wearing a classic roster, not a reprint of old cards.
