# Shellder #31/146 — XY

## Summary

Shellder is a bulk common from the XY base set, a Kanto Water Basic that filled out binders and starter decks without ever being a pull anyone cheered for. Naoyo Kimura's illustration and the Gen I pedigree give completionists a small reason to keep a copy around. A $0.20 modelled guide, flat over 30 days on 3 copies traded, says bulk, with 239 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.
