# Foongus #12/114 — Steam Siege

## Summary

Foongus is the Poké Ball lookalike that made players do a double take in Black and White, and its Play Ball ability gave Steam Siege a small engine for recycling Poké Balls in Grass decks. As a common it was bulk by rarity, so demand is nostalgia plus a little Yuka Morii loyalty. At a $0.43 modelled guide, up 30% over 30 days on 102 copies traded, with 609 days of inventory on the board, 74% of this printing’s price is collector premium, since the same card plays for $0.11 out of Black Bolt; PSA does not split this card’s population by finish, so no gem rate can be read for it.
