Mixed Azelf
With its great coverage, 125 base SpA and Nasty Plot, Azelf is primarily used as a special attacker, with the only physical moves it typically runs being either U-Turn or Explosion on specific sets. A Psychic type special attacker with access to neither Focus Blast nor Aura Sphere is the perfect Pokemon for Tyranitar to switch into, right?
However, Azelf also has an incredible base attack stat of 125 and access to physical Fighting coverage in Drain Punch. Not only does this hit Tyranitar for 4x super-effective damage, but also bypasses the SpDef of sand.

I use Mystical Power because I initially wanted Nasty Plot, but only having two spare moveslots severely cut into Azelf's coverage. Mystical Power allowed for a middle ground, allowing SpA boosting to tempt Tyranitar in while allowing two coverage moves. Flamethrower offers super-effective coverage against the Steel and (most) Dark types in the tier that resist Mystical Power. The final move is Shadow Ball so that you aren't completely ineffective against Armarouge and Delphox, but could be swapped for Energy Ball/Grass Knot for better coverage against Krookodile, Mudsdale and Tyranitar.
Tera Fighting allows Azelf to resist both of Tyranitar's STAB moves so it can revenge kill, since it is barely slower than +1 Jolly Tyranitar.
