heh, Sceats and I have made a bunch of teams surrounding SD + Agility Kingler in NU. It does take quite a bit of support, such as Screens and SR, and sometimes even Paralysis and Sleep. The idea is you decapacitate strong special forces on the opponents team, and then switch in Kingler after say Memento Gardevoir has set up DS. Then you first use Agility, as the opponent will barely scratch Kingler's defenses thanks to reflect + -1 Attack, and the SD up on the attack of the next mon. Hopefully, that mon will be physical, hence not dealing too much damage to you. After that you are pretty much free to sweep till victory!
