Why this card matters
pop
42 listings and a strong PSA 10 premium (~30x raw) suggest meaningful graded scarcity, but PSA 10 comps at n=5 and only one CGC9 sale make the sample too thin to trust deeply.
demand
Mewtwo carries durable nostalgia and broad collector appeal, but this is an oversized promo variant — a niche format that meaningfully limits the buyer pool versus a standard holo.
artist
Oversized promos use standard art reprints rather than exclusive alt-art illustration, so there is no meaningful artist-driven desirability premium here.
catalyst
21.2% 30-day momentum is notable but built on very low transaction volume (n=5 PSA 10 sales), making the move fragile and hard to distinguish from noise.
