# Arbok #35/165 — Expedition Base Set

## Summary

Arbok has long been a favorite among Gen I loyalists, the Team Rocket cobra that never got a flashy modern revival. Kyoko Umemoto's name adds a small draw for illustrator completists, and a Rare in Expedition's e-Reader era sat mid-tier: sought mostly by nostalgic binder builders, not competitive players. The modelled guide sits at $16, up 10% over 30 days on 21 copies traded, with 242 days of inventory on the board; a ACE 10 brings $241, 15 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
