# Great Ball #90/113 — Delta Species

## Summary

Great Ball is a utility Trainer from the EX era, a bench-filling search card that fed setup-heavy decks of its day but was never a centerpiece. As an Uncommon in a set built around Delta Species Pokémon, demand is quiet, mostly completionists and Nakaoka's steady, long-running illustration work. A $0.81 modelled guide with no copies traded in 30 days says bulk, and the economics stop there: no PSA population is on file.
