Scarf basculin can destroy Lando, outspeeding scarf Lando and clicking ice beam. It has same base HP as Koko, meaning that clicking final gambit on it takes it out of the game. Surf for adaptability boosted. Head smash for revenging zard x and mega pins, as well as doing good just hitting a lot of flying mons or Superpower for grens, kyu-b's, ttars and the like. I'll bet you can tear up the Overused tier with it.
