Absolutely. Their stat total is 700, putting them 20 points ahead of Mewtwo, and only 20 behind Arceus. It also has a base 170 in its main attacking stat, so with that and Outrage/Draco Meteor, if the opponent doesn't immediately outspeed it, something's going to die.
Nuzlocke update, made it through gyms two and three moderately underleveled but with almost no casualties, (none in the gyms proper, due to fortunate catches). Burgh is officially the creepiest gym ever, what with the cocoons and the clowns and the eerily-remixed gym theme. I just beat Colress on Route 4, and am about to see what I catch. *Hopes for a Sandile or Trapinch*
