# Diancie ◇ #74/131 — Forbidden Light

## Summary

Diancie is a Mythical Pokémon with a devoted Kalos-era following, and this Prism Star version played support, its Bench ability boosting Fighting attackers. Its mid-tier Rare slot made it a working pull rather than a chase, with kawayoo's illustration adding some collector appeal. The modelled guide sits at $19 with 51 copies traded in 30 days; a PSA 10 guides at $317, 17 times raw, but a 13% gem rate against $85 of fees makes grading a losing trade.
