# Metagross GX #157/145 — Guardians Rising

## Summary

Metagross GX was a staple of Sun & Moon-era Metal decks, its Geotech System ability refueling the board from the discard pile while Algorithm GX dug out the missing pieces. As a secret rare pulled from deep in the set, it pairs a Hoenn fan favorite with genuine scarcity. The modelled guide sits at $43 with 9 copies traded in 30 days; the slab is the real edge, with PSA 10s at $381 and a 46% observed gem rate putting about $70 of expected profit per submission, and the slabbed population has not grown in 30 days, slower than 86% of tracked cards.
