Grrr, I'm mtr12, not "that guy".
The reason I used Dialga is that I wanted to only test one variable (Ninjask) rather than two (Ninjask and BP Scizor). Aldaron or someone had used the Dialga set I list below successfully during previous Ninjask tests, so I made Dialga a control.
Scizor is perfectly viable, though, because he's pretty solid in Ubers. The idea of an extended Baton Pass chain in Ubers hasn't really been explored, but its worth a shot.
Here is the Dialga set I (re)used.
Dialga @ Lum Berry
Ability: Pressure
EVs: 6 HP/252 Atk/252 Spd
Adamant nature (+Atk, -SAtk)

You could try fitting in Draco Meteor somewhere if you were inclined to do so, I guess. Probably over Stone Edge, but then Lugia will be troublesome. To tie this back to the topic at hand: If you use Draco Meteor, Draco Plate becomes a viable item because you fit the criteria of having 2 STAB moves of the same type.
