>>45622321Depends heavily on the Pokemon and its movepool, but 140 base Attack + item + (potentially) an Ability is very good to start with. Shitty STAB options can undercut that, though, so Rock's poor offerings and missing out on Brave Bird would definitely hurt Archeops. If Game Freak got their heads out of their collective asses and spread around Accelerock like they did for EVERY OTHER QUICK ATTACK CLONE so non-Defeatist Archeops had a decent option for scaring away faster foes
or just gave the dino-bird Unburden the thing could easily be OU-viable, if not OU by usage.
On further reflection, mixed Unburden Archeops would be goddamn amazing. STAB Power Herb Meteor Beam off of a boosted base 112 Special Attack stat on turn 1 to double your Speed, STAB itemless Acrobatics as the perfect chaser, and a slew of powerful coverage options to round out the set.
