Slash Taunt with Toxic, it let you wreck Wobbuffet, Lugia, Giratina and other stallish mons like them and can come in a handy vs Calm Mind user like Mewtwo or Lugia (again). Its useful enough to be slashed and removed from AC. You dont really need speed when using Taunt, 8 EVs is good to outrun other Skarmory, though.

Dragon resist ? Mention it if you do it for the Grass type.
