# Killer #OP10-106 — Royal Blood

## Summary

Killer is Eustass Kid's right hand, the masked Slasher of the Kid Pirates, and fans prize his quiet loyalty and the twin blades hidden in his forearms. This Royal Blood uncommon, released in March 2025, is a yellow three-cost Slash character whose On K.O. effect digs three cards deep for a Supernovas or Kid Pirates card, so it replaces itself when removed. The art shows him mid-leap in his blue-striped mask against a violet burst, a base print with an uncommon's modest pull rate. A $0.10 modelled guide, up 11% over 30 days on 26 copies traded, says bulk, with 1,906 days of inventory sitting on the board, and the economics stop there: no PSA population is on file.
