Riolu is caplable of OHKO or 2hko most leads in LC.One Advantage Riolu has is InnerFocus on the Scarf Lead because pokemon with fake out still take a full hit from Riolu putting them in a switch of die position if the werent Ko'd.
With A Focus Sash i would Recomend Stead Fast As you can Profit from the speed boost and attempt a sweep from the start. ThunderPunch and Ice Punch allow Riolu to go right past Gliscor and Mantyke, ( the first can get OHKO on the switch in if predicted correctly). With Agility you want InnerFocus. Naughty is Only ran if you choose to use Vaccuum wave to hit Scarf Users.
Other Options, With Stead Fast or Agility you can run Oran Berry to keep Riolu Alive and Continue to attempt to sweep after the speed boost.
