Why this card matters
pop
204 raw listings and modest graded sample sizes (PSA 9 n=5) suggest ample supply; the PSA 9 premium (~15x raw) reflects grading upside but not true scarcity.
demand
Mewtwo carries enduring nostalgia and broad collector appeal, but as a Black Star promo it sits below chase-set status and draws casual rather than deep demand.
artist
Standard holo promo illustration with no notable alt-art treatment or sought-after artist signature to drive premium desirability.
catalyst
30-day momentum is firmly negative at -22.2% with no visible event, reprint, or tournament relevance to reverse the current downtrend.
