# Mewtwo EX #158/162 — BREAKthrough

## Summary

Mewtwo is the original Gen I powerhouse, a fan favorite whose EX printings always draw collectors, and this one sits in the ultra rare tier of BREAKthrough, where EX pulls were the real chase. Damage Change gave it a distinctive tricky role in XY-era decks. The modelled guide sits at $90, up 2% over 30 days on 63 copies traded, with 100 days of inventory on the board; the slab is the real edge, with PSA 10s at $6,000 and a 16% observed gem rate putting about $780 of expected profit per submission.
