# Cool Porygon #15 — Wizards Black Star Promos

## Summary

Cool Porygon is a quirky Wizards-era promo for a Gen I oddity that fans have always found oddly lovable, and Sugiyama's name adds a small illustrator hook. Its weak attacks kept it out of competitive play, so demand rests on promo completists and Porygon devotees. The modelled guide sits at $90, flat over 30 days on 88 copies traded, with 220 days of inventory on the board; the slab is the real edge, with PSA 10s at $6,300 and a 4% observed gem rate putting about $110 of expected profit per submission, with original packs long past any pull-rate math.
