*side note*
If you are curious...
I need it for (possibly) all of the following...
Outspeed, and OHKO Excadrill during a Sandstorm.
Outspeed, and OHKO Skarmory, Starmie, Jellicent, and Politoed.
Revenge kill Tyranitar.
Revenge kill Gyrados after one or two Dragon Dance boosts.
...a Modest, HP Fighting Jolteon w/ Quick Feet can do all of that. No turns to set up required.
