Since no one is posting, I'll post. This is a very weird Tyranitar. A SubCurseTar, heh. How about that? lol.

Tyranitar@Leftovers
Ability: Sand Stream
EV: 252 HP / 92 Atk / 160 SpD
Careful Nature
- Substitute
- Curse
- Payback
- Earthquake
This set is not tested yet, so I don't know whether it will work or not. Anyways, to explain the Moves, EV's and Nature. If Tyranitar hides safely behind a Substitute, it can easily get a Curse or 2, and if that happens, Tyranitar will be hard to take down. Payback is your STAB move, why not Crunch? Crunch only has 80 BP(120 w/ STAB) while Payback has 100 BP(150 w/ STAB). Tyranitar is very slow without speed EV's so 100 BP. Payback can easily take down pokemon like Latias, Azelf, Celebi, Cresselia, Dusknoir, Rotom formes and other. If you play this properly and you always keep Tyranitar's Substitute, you can beat every threat. Earthquake solves you problem against Lucario, Scizor, Tyranitar, Metagross, Magnezone, Jirachi, Forretress, Empoleon and Electivire. Like I said, If you can keep Tyranitar a Substitute then you can beat Salamence. Salamence takes
53.78% - 63.44% from unboosted Payback, add in Stealth rock you have Salamence taking
78% - 88%, hmm....I think were forgetting something, ah.. Add in Life Orb and Residual damage, Salamence takes
94% - 104%. So, there, I haven't tested yet but what do you think?
NOTE:
The calculations assume that Stealth Rock is on the field when it switches in. The 94% - 104% assumes that Salamence attacks.
