# Hydreigon #86/114 — Steam Siege

## Summary

Hydreigon is the Unova pseudo-legendary that fans rank among the best Dark and Dragon designs of Gen V, so demand rarely fades. Here it's a standard Rare, a mid-tier pull in an XY set where the real chase sat elsewhere, with Hideki Ishikawa as illustrator. A $0.42 modelled guide, down 5% over 30 days on 8 copies traded, says bulk, with 224 days of inventory on the board, and the economics stop there: a CGC 10 brings $11, 25 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
