# Hack #OP10-051 — Royal Blood

## Summary

Royal Blood arrived in March 2025, and Hack came with it as a plain Uncommon, the base print of a cost-four Blue Character. He is the fish-man karate master who fought beside the Revolutionary Army and served among Dressrosa's gladiators. The art shows him mid-stance in a white gi, with a long blue mane and a stern scowl against a golden, sunlit arena. On attack he digs three cards deep for a Revolutionary Army Character, so players slot him into OP10 builds as a steady searcher, not a showpiece. A $0.07 modelled guide, up 40% over 30 days on 23 copies traded, says bulk, with 466 days of inventory on the board, and the economics stop there: no PSA population is on file.
