Why this card matters

pop

184 raw listings signals healthy open-market supply, and PSA 10 comps at n=5 suggest only modest graded scarcity despite the 23× raw-to-PSA10 premium.

demand

Metagross has cult nostalgia but is not a top-tier chase Pokémon, and the GX era is broadly loved yet crowded with more iconic alternatives.

artist

Standard Rare Ultra holo treatment with no alt-art or standout illustration distinction to drive collector premium above the set baseline.

catalyst

A 2.2% 30-day price move on thin PSA 10 comp volume (n=5) is too fragile and slow to signal a credible near-term catalyst.
