>>18206786As potent as Bisharp is this generation, I believe 'Mons like Conkeldurr, Mienshao and Heracross would like to exchange words.
True, not everybody packs them, but any good Fighting type can stop Bisharp dead in its tracks unless it's buffed off a couple SDs and...is running Aerial Ace, I guess, and that's not massively common on 'em.
Such a Mega would face similar problems. Effective, but easily stopped if the opponent has the right tool at their disposal. Then again, that can be said for a lot of others who are also effective.
