# Mew ex (Japanese) #001 — SVN: Battle Partners Deck Build Box

## Summary

Japan got this Mew ex in January 2025, well over a year after the English card arrived in the 151 set in September 2023, so the Japanese edition is the later arrival here. It comes from the Battle Partners Deck Build Box, a promo-tier slot rather than a booster chase pull. Mew floats upside down in pink bubbles over a sparkling cosmic backdrop, glancing back with big blue eyes, and that charm keeps Mew a perennial favourite. The modelled guide sits at $6.66 with no copies traded in 30 days; no PSA population is on file, and a CGC 10 would fetch about $20 against $45 in grading fees, so the only money in this card is finishing a set, not a slab.
