# Ogre's Mask (Japanese) #137 — SV8a: Terastal Fest ex

## Summary

Ogre's Mask is a bulk common in the Japanese Terastal Fest ex set, and that is the honest ceiling for a Trainer item that swaps a mask-wearing Ogerpon ex out of play. The artwork lines up Ogerpon's four masks in teal, red, blue and grey against a rainbow swirl, which makes it a cheerful binder filler. It reached Japan in December 2024, ahead of the English Prismatic Evolutions version in January 2025. A $0.12 modelled guide with no copies traded in 30 days says bulk, and the economics stop there: no PSA population is on file.
