Why this card matters
pop
Only 38 listings and a steep raw-to-PSA9 premium (~11x) signal constrained graded supply, but the PSA9 comp cluster (n=3) is too thin to confirm structural scarcity.
demand
Mewtwo carries elite nostalgia and character pull, but this is a holo promo reprint rather than a vintage or chase set card, which tempers ceiling demand.
artist
Standard Ken Sugimori-style promo holo with no notable alt-art or illustration prestige — aesthetically competent but not a collector conversation piece.
catalyst
20.3% 30-day momentum is real but fragile given only 3 PSA9 sales driving it — one soft comp collapses the signal entirely.
