Great guide, I tryed the strategy you suggested and it really works. I had a team with Ninjask, Marowak, Magneton and Suicune and some other stuff like that so mainly I would pass a swords dance and +3 speed to marowak, and if it worked, it would almost be always a 6-0. Magneton would kill skarmory if it came in the way.
Incase you are wondering, I tried both Jaskwak and Joltwak - I found Jaskwak to be much better. First of all, you can baton pass swords dances over to Marowak, and sweep your opponent's team right away without needing Marowak to swords dance itself and get damaged. Magneton in your team can easily shut down your skarmory problem, meaning you will have no problem with Skarmory PHazing you.
And again, great guide.
