# Master Ball #99/113 — Delta Species

## Summary

Master Ball is a deck-thinning Trainer from the EX era that searched deeper than most peers and fed the Stage 2 engines of its day, so it saw real play. Uncommon here means plentiful, so demand rests on nostalgia for the name and the clean utility, not scarcity. A $0.61 modelled guide, up 7% over 30 days on 15 copies traded, says bulk, with 269 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.
