Why this card matters
pop
95 raw listings and modest graded sample sizes suggest moderate availability; the PSA 10 premium (24x raw) is striking but rests on only n=2 sales, making true scarcity hard to confirm.
demand
Blastoise carries strong Gen-1 nostalgia but as a Black Star Promo EX rather than a vintage or chase set card, collector pull is middling and broadly competed.
artist
Standard XY Black Star Promo holo treatment with no notable alt-art or sought-after illustrator credit to drive illustration-specific desirability.
catalyst
A sharp -37.3% 30-day momentum signal is a clear headwind with no visible positive catalyst to suggest a near-term reversal.
