Sawk having the ability Sturdy, can Take any hit from ditto needed, Give him a Choice Scarf,
This how you have to go about it though,
Pokemon Comes in, Beasts your opponent, Ditto comes in, Let it faint the pokemon you have in
After it faints your current pokemon, send in Sawk with Choice Scarf.
If its Scarfed, You are at equal speed, and have a chance of taking it down with 1 close combat, if its Sashed, then you are faster, You hang on with Sturdy, it hangs on with sash, but with your capobility of outspeeding it, you WILL win the match up.
This is the exact stuff for said Sawk.
