# Marshadow #103/236 — Cosmic Eclipse

## Summary

Marshadow is a Mythical from Alola with a devoted fanbase, and its mimic-style attack gave this printing a niche but real role as a tech option against decks built around non-GX attackers. Mid-tier rarity in a big Sun & Moon finale keeps it a solid pull rather than a chase. The modelled guide sits at $5.62, down 1% over 30 days on 54 copies traded, with 263 days of inventory on the board; a PSA 10 brings $450, 80 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
