# Hyper Devolution Spray (Japanese) #031 — Pokemon Web

## Summary

Uncommon is the middle tier of this set, and Hyper Devolution Spray sits there as a Trainer worth owning for its place in the Japanese Pokemon Web release of October 2001 rather than for any chase appeal. The card itself is a gold-bordered Trainer, with a yellow spray bottle misting a fine jet across a blue, streaked background. A functional pull at this tier keeps it approachable for anyone completing the run. The sold median sits at $9.00 with 2 copies traded in 30 days, with only 30 days of inventory on the board; no PSA population is on file, and a PSA 10 would fetch about $40 against $65 in grading fees, so the only money in this card is finishing a set, not a slab.
