First turn, I look at the opponents. If there is any physical threat to Ninetales (equakers, rock sliders, etc.) then I burn it with Banette’s will-o-wisp. If there is anything that Banette could get a cheap OHKO on, I shadow claw or even shadow sneak it. While Banette does whatever it does, Ninetales uses nasty plot. The next turn, I use Will-O-Wisp on Ninetales to activate Flash Fire, and then I sweep with Heat Wave. If ninetales or Banette happen to faint, Greninja has a helpful move in Mat Block that allows Ninetales or Samurott to set up safely, or Banette to set a sub. Protean, great coverage with ice, dark, and water, and an expert belt makes greninja very strong. Samurott can set up Swords Dance and use STAB priority Aqua Jets, can cover grass with Megahorn, and cam just use powerful STAB aqua tails.
