# Master Ball #88/107 — Deoxys

## Summary

Master Ball is a Trainer that dug seven cards deep for a Pokémon, which made it a handy consistency tool in its day, though never the format-defining engine that Supporters became. As an uncommon it was an ordinary pull, so interest now comes from players and completionists rather than chase-hunters. A $0.48 modelled guide, down 2% over 30 days on 9 copies traded, says bulk, with 254 days of inventory on the board, and the economics stop there: PSA does not split this card’s population by finish, so no gem rate can be read for it.
