# M Blastoise EX #18/83 — Generations

## Summary

Mega Blastoise EX pairs one of the original starters' final forms with the Mega mechanic, and Gen I's Kanto starters always carry loyal nostalgia behind them. In Generations it was a top-tier chase pull, so demand rests on fan devotion and that scarcity inside a celebratory anniversary set. The modelled guide sits at $31, down 1% over 30 days on 44 copies traded, with 156 days of inventory on the board; the slab is the real edge, with PSA 10s at $900 and a 12% observed gem rate putting about $24 of expected profit per submission.
