Why this card matters

pop

PSA 10 pop of 2,737 is massive for a secret rare — supply pressure is real. High submission volume (16,400 total) signals wide availability. Low scarcity conviction.

demand

Mewtwo is top-tier iconic IP with enduring global pull. GX era has a loyal cohort. Character demand is durable, but not at the acute spike level of a 1st-gen Base Set card.

artist

Secret-rare full-art holofoil finish elevates visual appeal. Mewtwo-GX art is dramatic and well-regarded, but not a landmark composition that commands a standalone premium.

catalyst

9% 30d momentum is modest and the BGS 10 outlier ($75,100) badly skews comp perception. No confirmed event or reprint news driving urgency. Fragile signal on thin recent data.
