🚀 Behavioral Economics: Why These Cards Skyrocket
1. Exclusivity + Nostalgia (Scarcity Effect)
Promo cards tied to events, tests, or collabs are inherently limited. They trigger emotional and FOMO-based buying.
2. Anchoring Bias
Initial pricing feels low — so once prices surge, they still seem like a bargain compared to set-based trophies.
3. Availability Heuristic
People invest more in what they frequently see — but with these promos, fewer listings means more desire.
💡 How to Buy These Safely
-
Use Japanese proxy services for Mercari, Yahoo Auctions Japan, or Mandarake.
-
Buy graded versions from PSA/BGS to guarantee authenticity.
-
Check population reports on PSA: ultra-low population equals future potential.
