# Blastoise EX #XY30 — XY Black Star Promos

## Summary

Blastoise EX in the XY promo run carries a starter-line fanbase that has never really thinned, since Kanto's Water finale is a childhood favorite. Promos sat outside the booster chase, so demand comes from completists and players, and Eske Yoshinob's name adds a small draw. The modelled guide sits at $9.83 with 37 copies traded in 30 days; the slab is the real edge, with PSA 10s at $1,500 and a 18% observed gem rate putting about $150 of expected profit per submission, and the slabbed population has not grown in 30 days, slower than 86% of tracked cards.
