# Island Cave #89/101 — Hidden Legends

## Summary

Island Cave is a niche Stadium that mostly served as a fringe tech against Special Condition decks, never a format staple, and its uncommon slot made it ordinary filler within Hidden Legends. Collector interest comes from Ken Ikuji's name on the credit and from EX-era completionists finishing the set. The modelled guide sits at $1.38 with no copies traded in 30 days; PSA does not split this card’s population by finish, so no gem rate can be read for it.
