Hidden Power Fighting is necessary to beat Snorlax, who otherwise laughs at Chandelure while Pursuiting it or simply Phazing.
This team doesn't feel like it has a lot of direction to me. Chandelure rips huge holes in specially bulky Pokemon, but your team can't exploit that because Suicune is the only other Pokemin hitting from the special side, and it takes so long to boost up to a reasonable power level that the opponent will have healed off the damage from Chandelure's rampage before they are forced to take it on. I would strongly consider either changing Chandelure to a Subtitute set so that it can actually do some sweeping or changing Suicune to offensive CM so that it is better able to exploit the holes Chandy punches. Right now this just seems like you threw some strong Pokemon together with no goal or concept and called it a team.
