Won't Skarmory just Whirlwind you away if you use Knock Down? I understand if it's on the switch but otherwise it'll just be a waste, even though it's nice on Bronzong.
Well, yes and no. Knock Down at the moment isn't looking like such a competitively valuable move in most occasions. Skarmory, after seeing Giga, will most likely not expect Knock Down, but would instead be expecting an easy set up. With Roost, it can easily take Stone Edges, and Giga's other moves don't threaten it at all. On the other hand, even if the opponent anticipated my strategy and tried to Whirlwind my Pokemon away, I will have still gotten in Knock Down and Skarmory will be vunerable to Earthquake from another one of my sweepers (or other moves, depending on who gets switched in). Either way I get the advantage and Skarmory doesn't get to set up like it wanted to.
Still, any advice on another filler move I could use instead? Perhaps one not listed?
