# Sigilyph GX #222/214 — Lost Thunder

## Summary

Sigilyph GX is a Secret Rare in a set stacked with bigger names, so it was never the obvious chase, which is exactly why Gen V Psychic fans and Alola-era completionists quietly prize it. Mirror Counter made it a deliberate anti-GX tech, and PLANETA Igarashi's name adds a draw of its own. The modelled guide sits at $10, up 5% over 30 days on 8 copies traded, with 455 days of inventory on the board; the slab is the real edge, with PSA 10s at $761 and a 31% observed gem rate putting about $110 of expected profit per submission, and the slabbed population has not grown in 30 days, slower than 86% of tracked cards.
