So I've been using this as a lead to some success
Togekiss @ Light Clay
Calm
Serene Grace
EVs: 252 HP/240 Def/16 SDef
-Reflect
-Light Screen
-Tri Attack
-Air Slash/Aura Sphere
It is a dual screen lead. The EVs should give a balanced physical/special spread. I have been able to use it to set up screens both at the beginning and later on, since it is bulky enough to switch in and take hits with no stealth rock in play. Tri Attack can 2HKO Azelfs who Taunt first turn. Aura Sphere is good to dent Tyranitar leads, but since it only does 15-18% to a 240/184 with a positive nature, it is better just to set up a reflect and switch out to a better counter.
