# Thunder Mountain ◇ #191/214 — Lost Thunder

## Summary

Thunder Mountain was a Prism Star Stadium that discounted Lightning attacks for both players, so it lived in Lightning-heavy lists rather than every deck. Prism Star rarity gave it modest collector interest, helped a little by 5ban Graphics' name on the credit line. The modelled guide sits at $1.53 with 23 copies traded in 30 days; a PSA 10 guides at $60, 39 times raw, but a 14% gem rate against $85 of fees makes grading a losing trade.
