# Bronzong #SWSH091 — SWSH Black Star Promos

## Summary

Bronzong's Metal Transfer was a genuine engine for Metal decks, shifting Energy freely between attackers, which gave this promo real competitive pedigree in a format that rewarded Energy acceleration. Atsushi Furusawa is a long-serving Pokémon illustrator, and a Black Star Promo stays an easy, affordable pickup for Sinnoh fans. At a $3.18 modelled guide, flat over 30 days on 10 copies traded, with 278 days of inventory on the board, this printing is almost entirely collector premium, since the same card plays for $0.04 out of Surging Sparks; a PSA 10 brings $125, 39 times raw, but a 36% gem rate against $85 of fees makes grading a losing trade.
