# Rotom #50/156 — Ultra Prism

## Summary

Rotom was a deck-builder's puzzle in Ultra Prism, built around stuffing the discard pile with Tools until its attack came free, a niche gimmick rather than a format-definer. As an uncommon mid-tier pull, its demand comes from Sinnoh nostalgia for the Plasma Pokédex favorite and Naoyo Kimura's work. A $0.21 modelled guide with no copies traded in 30 days says bulk, and the economics stop there: a PSA 10 guides at $31, 147 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it, and the same card plays for $0.09 out of Surging Sparks.
