# Mewtwo EX #157/162 — BREAKthrough

## Summary

Mewtwo is the Gen I Pokémon collectors never stop wanting, and a full-art EX from the XY years sits right where nostalgia and playability overlap. Ultra Rare here meant a true chase pull, and Ryo Ueda's name adds a quiet draw for illustrator collectors. The modelled guide sits at $82, up 11% over 30 days on 97 copies traded, with only 10 days of inventory on the board; the slab is the real edge, with PSA 10s at $4,900 and a 11% observed gem rate putting about $410 of expected profit per submission, and the slabbed population is growing 2% a month, faster than 88% of tracked cards.
