The artwork for the 2021 Celebrations #23 card was created by KIYOTAKA OSHIYAMA.
The 2021 Pokémon Celebrations #23 card features the Regulation Mark D.
As a functional Supporter card within the Pokémon TCG, its utility is tied to the current meta's reliance on Professor Oak's lineage, driving steady demand from players. While it lacks the ultra-rare status of secret rares, the Celebrations set's commemorative nature attracts collectors seeking nostalgia, creating a floor of demand beyond pure gameplay. The presence of active listings suggests a liquid market where supply meets this consistent, albeit moderate, collector interest.
Categorized as a Holo Rare, this card represents a mid-tier rarity within the Celebrations set structure, distinct from higher-tier variants but more sought after than commons. The holographic finish adds a layer of visual appeal that separates it from standard printings, appealing to those who prioritize aesthetic presentation over sheer scarcity. Supply is constrained by the finite print run of the Celebrations expansion, which was produced to commemorate the franchise's anniversary.
The Celebrations set benefits from significant nostalgia factors, ensuring long-term interest from completionists aiming to fill gaps in anniversary-themed collections. While meta rotation may dampen speculative hype for playable-only cards, the commemorative status provides a buffer against total obsolescence. Crossover demand from art collectors and franchise historians may sustain value more effectively than pure gameplay utility alone.
