# Yanmega #XY144 — XY Black Star Promos

## Summary

Yanmega is a Sinnoh-era Bug that never topped popularity polls, so demand here comes from a promo's scarcity and a quirky Ability that rewarded careful hand-sizing. Midori Harada is a respected name in Pokémon illustration, though a Black Star promo sits well outside the chase tier. At a $12 modelled guide, this printing is almost entirely collector premium, since the same card plays for $0.28 out of SVP Black Star Promos; no PSA population is on file.
