Why this card matters
pop
122 raw listings is a healthy supply pool, and graded sample sizes (n=1–2) are far too thin to confirm real scarcity despite the 8x PSA 9 premium over raw.
demand
Groudon carries solid Gen III nostalgia and competitive relevance, but as a widely distributed XY Black Star promo it lacks the rarity mystique that drives intense collector demand.
artist
Standard holo promo treatment with no notable alt-art or standout illustration distinguishes this card from the crowd of EX-era promos.
catalyst
30-day momentum is negative at -8.3% with no identifiable near-term catalyst, indicating softening rather than a dislocation buying opportunity.
