# Greninja EX #XY20 — XY Black Star Promos

## Summary

Greninja EX is a Kalos starter that became one of the most beloved final evolutions ever, and its fanbase has stayed loud for over a decade. As a Black Star promo it was never a booster pull, so scarcity comes from distribution, with 5ban Graphics supplying the artwork. At a $31 modelled guide, with 27 copies traded in 30 days, this printing is almost entirely collector premium, since the same card plays for $1.39 out of Stellar Crown; the slab is the real edge, with PSA 10s at $3,500 and a 10% observed gem rate putting about $190 of expected profit per submission.
