# Weakness Policy #164/160 — Primal Clash

## Summary

Weakness Policy was a Pokémon Tool that erased type matchups, which gave it genuine tournament use in the Primal Clash era. Its secret rare treatment put a Trainer in a slot usually held by Pokémon, and that oddity, plus Ayaka Yoshida's name, keeps collectors interested. The modelled guide sits at $7.42 with 2 copies traded in 30 days; a PSA 10 guides at $218, 29 times raw, but a 6% gem rate against $85 of fees makes grading a losing trade, and the slabbed population has not grown in 30 days, slower than 88% of tracked cards.
