# Nighttime Mine #197/217 — Ascended Heroes

## Summary

Nighttime Mine is a Stadium that taxes every Tera Pokémon's attacks, a pointed answer to the Tera-heavy decks that have dominated recent formats, so its value is as a tech slot, not a trophy. As a plain uncommon it sits in the bulk tier, with only tournament niche behind it. The modelled guide sits at $0.28, up 40% over 30 days on 431 copies traded, with only 25 days of inventory on the board; PSA does not split this card’s population by finish, so no gem rate can be read for it.
