Why this card matters
pop
103 listings is a moderately healthy supply pool, and the graded premium ($36 PSA8 vs $21 raw = ~71%) sounds large but is undermined by single-comp sample sizes — not enough data to confirm true scarcity.
demand
Swampert has a loyal Gen 3 fanbase, but EX promos from XY-era are plentiful and this specific card doesn't carry the character-icon status of a Charizard or Pikachu to drive sustained collector demand.
artist
Standard XY Black Star Promo holo treatment with no notable alt-art or standout illustrator credit to drive premium illustration-based demand.
catalyst
9.6% 30-day momentum is mildly positive but rests on an n=1 or n=2 comp foundation, making it statistically fragile and insufficient to confirm a real price dislocation.
