Riolu

As one of the few Pokemon with Prankster in Little Cup and even fewer that can warrant an offensive set, Riolu holds a specific niche as a revenge killer and late-game cleaner. With access to both Copycat and Prankster, it can fire off powerful High Jump Kicks and chain them together so the opponent cannot react. Prankster also makes sure that Riolu can set up Swords Dance before a Pokemon Taunts it. Its decently sized movepool gives it enough options to cover potential checks and a variety of threats. However, it is somewhat outclassed as a Fighting-type with Pokemon like Timburr and Mienfoo being dominant in the tier. Its Copycat chain is also easily interruptible through faster priority or Protect.
