Why this belongs on-site
Tyranitar is by far the most feared pokemon in the OU Tier, but most see him as a support pokemon that just sets up Stealth Rock and maybe a Choice Band. But what about a Mixed Sweeper, there is not to many of them, but the set I have on Tyranitar hits Almost Every Pokemon in OU Tier the Super Effectively except Sableye, Volcarona and Spiritomb. If there are other Pokemon that aren't hit super effectively please let me know.
Tyranitar [SET]
name: Mixed Sweeper
move 1: Superpower / Brick Break
move 2: Crunch
move 3: Fire Blast
move 4: Ice Beam / Stone Edge
ability: Sandstream
item: Expert Belt / Life Orb
nature: Brave
evs: 160 HP / 252 Atk / 96 Sp Atk
[SET COMMENTS]
-Powerful Mixed Sweeper
-The Evs are for more bulk to Tyranitar while maintaing an offensive force to be reckon with.
-Good on Trick Room Teams, but outside of Trick Room its completely slow.
-Hits every pokemon in the game (except Sabaleye and Spiritomb) super effectively
-Crunch gets rid of Jellicent who will try to Will-O-Wisp
-Superpower is the main selling point, as it KOs all Tyranitar's, Blissey, Chansey, Heatrans and Magnezone
-Ice Beam is good for picking off Dragons, Landorus and Gliscor
-Fire Blast is for Scizor, Ferrothorn, and Skarmory which are OHKO with Stealth Rock (I believe)
-Expert Belt is to increase super effective moves, well since he hits all pokemon thats an increase to boost.
-If the Attack Drop bothers you, you can opt for Brick Break, but it is less powerful.
[ADDITIONAL COMMENTS]
-The downfall of this set is that it needs Trick Room Support. Pokemon like Bronzong, Claydol, Lunatone, Solrock and Reuniclus that can handle the Sandstorm are great teammates.
-Tyranitar is still weak to Scizor's two STAB moves, but it can OHKO it back with Fire Blast.
-Slowbro is defiantly 2HKOed by Crunch, who can take it and Slack Off the damage.
-You can option for Life Orb damage, but I don't see why because the damage from recoil does add up.
-You can swap Ice Beam for Stone Edge to hit Volcarona super effectively but you lose out on hitting Landorus, Gliscor, Dragonite, who can KO Tyranitar with Earthquake.
[Teammates & Counters]
-Scizor is still Tyranitar's greatest nemesis. Teammates that can lure Scizor out and KO are great for Tyranitar
-Pokemon that can set up Trick Room and handle Sandstorm are great teammates
-A Pokemon that can set up Stealth Rock is needed for a sure OHKO by Tyranitar as the Sandstorm damage takes its toll on most pokemon.
-Spikes is also good but I believe Stealth is better.
-The pokemon that aren't 2HKO is Jirachi, I don't know why but I just can't seem to KO this pokemon without it 2HKO with Iron Head.
-Pokemon that can get rid of Celebi and Jirachi as they both pose a threat to Tyranitar's Sweep.
-If Tyranitar is Burned, its not too useless but is only limited to two moves.
