It also resists surf's so that's a plus. Better user of status moves also.
My primary attackers are Specs Hydro Pump Politoed and Muddy Water Kingdra, all the others pokemon in my teams are for support and/or counter common tactics (like prankster T-wave on my Kingdra, that's just nasty)
About Lanturn, I totally forget about him, but that Grass weakness don't give me many switch options, but hey, you cannot cover every weakness!
