oh maaaaan. it's such a beast.
what's there to learn though?
my only real "policy" i have is: if i get a good switch in and Toxic Orb gets activated, i just start attacking. BUT, if i switch in after a faint and Toxic Orb is not activated (Quick Feet is not activated), then i'll Swords Dance as they switch (obviously i'm not going to switch him in at all if it would not force a switch) and then level buildings.
as for a moveset, Facade is obvious. as a supplement, EQ and Crunch/Shadow Claw offer excellent coverage. Close Combat is tempting, but floating Ghosts will laugh in your face.
any other questions?
