# Keldeo #XY118 — XY Black Star Promos

## Summary

Keldeo is a Unova mythical with a loyal following, a Water/Fighting swordsman built on the Swords of Justice story, and this promo's anti-Darkness Ability gave it a defined job in its era. Promo cards like this one sit outside the booster chase, so demand stays steady and collector-driven rather than pull-driven. At a $30 modelled guide, with 36 copies traded in 30 days, this printing is almost entirely collector premium, since the same card plays for $0.11 out of Temporal Forces; the slab is the real edge, with PSA 10s at $8,177 and a 3% observed gem rate putting about $66 of expected profit per submission.
