As you can see, Ambipom has a wide movepool and an actually useful ability (see: Technician). With this, it can actually be usable since it has some attack power and fairly good speed.
Movesets:
Ambipom @ Leftovers
-Substitute
-Baton Pass
-Thunder Wave/Agility
-Return
The idea is simply to pass substitutes, something that is always useful. It can also pass some Agilities, which is good too.
Ambipom @ Leftovers
-Substitute
-Screech
-Shadow Claw
-Return/Focus Punch/Brick Break
This is similar to the ADV Screechgon. Screech to lower defenses and hit with Shadow Claw (to beat Ghosts). Return is for STAB, but Focus Punch will land a powerful hit. Brick Break is actually a very good choice, because of Screech, which means that it will hit harder than usual.
