# Lake Boundary #112/123 — Mysterious Treasures

## Summary

Lake Boundary is a Stadium that reversed the usual arithmetic by doubling Weakness for both players, so it only earned a slot in decks built to punish a specific matchup. Ryo Ueda is a long-running Pokémon illustrator, but the draw here is its mid-tier rarity and its odd role as a Diamond & Pearl-era curiosity. A $0.53 modelled guide with 9 copies traded in 30 days says bulk, and the economics stop there: no PSA population is on file.
