# Professor Birch #82/106 — Emerald

## Summary

Professor Birch is the Hoenn professor, a Supporter that refilled a hand to six and gave decks of the EX era a reliable draw engine. Sugimori's name adds quiet prestige, and as an uncommon trainer it was a working pull, not a chase slot. A $0.41 modelled guide, down 2% over 30 days on 2 copies traded, says bulk, with 697 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.
