Good news everyone!

Please Note that the title has absolutely nothing to do with the team itself and was merely used to draw eyes.
*Good News Everyone*​

This is a Trick Room team that was built around the use of Tyranitar. Tyranitar is a very strong pokemon, and with as slow as it is, it makes a wonderful user of Trick Room.​

This team hs gone through many variations from as little as switching Smeargle and Bronzong's places to something as big as switching Rampardos to Tyranitar.​

This team does have what I believe to be a slight problem with Fighting Type Pokemon, and especially Machamp and Hariyama, who destroy me with Dynamicpunch or counter Tyranitar, respectively. This team is built for OU in 4th gen, and any fixes or tweaks may be appreciated.​

Without further ado, I am proud to present the actual team, and I thank you for reading this far~​

Team Building:

I started off simple, take the most threatening sweeper in OU and slap it in, base a team around it. Simple enough.

I needed a pokemon to resist his worst nightmare, and that someone was cresselia. Cresselia can effectively set up Trick Room and Screens for Tyranitar, heal him and resist Fighting attacks.

Next: a lead. I chose Bronzong because of his Bulk, ability to Trick Room and defend against common leads. It is immune to Tyranitar's Ground Weakness as an added bonus.

Now I realized Bronzong was something I had to preserve to protect Tyranitar better. So Smeargle went to the front as a good Suicide Lead with Trick Room.

At this point, I lacked a Special Attacker and Water Resist. Octillery, with such a powerful Water Spout and massive diversity, can fill this perfectly. Bam.

Now I realized if I run out of Trick Room users, I need something fast to wrap things up. Weavile is a good pokemon, since it can effectively sweep end-game.​

Smeargle (M) @ Focus Sash
Ability: Technician
EVs: 252 HP / 252 Atk / 4 Def
Brave Nature (+Atk, -Spd)
- Protect
- Trick Room
- Fake Out​

- U-turn

Smeargle is an absolutely unpredictable pokemon. It can fill almost any possible role. A Trick Room Anti-Lead is the case here. Simply Protect or if my opponent has Fake Out, I can protect. U-Turn if he can, but he is frail and replacable.​

Cresselia (F) @ Light Clay
Ability: Levitate
EVs: 252 HP / 252 Def / 4 SDef
Relaxed Nature (+Def, -Spd)
- Reflect
- Light Screen
- Trick Room​

- Lunar Dance

Cresselia is a great pokemon that can support the team and make it almost impossible to beat. Reflect and Light Screen make every member of my team (barring Smeargle) difficult to OHKO. Lunar Dance can heal a weakened sweeper or allow Bronzong another Trick Room.​

Bronzong @ Leftovers
Ability: Levitate
EVs: 252 HP / 92 Def / 164 SDef
Sassy Nature (+SDef, -Spd)
- Trick Room
- Stealth Rock
- Gyro Ball​

- Reflect

Bronzong is a great utility, and since Stealth Rock is neccesary for Tyranitar, I needed it. Gyro Ball let's him hit for massive damage, and Reflect makes walling easier, since I made him weaker on that side.​

Tyranitar (M) @ Choice Band / Macho Brace
Ability: Sand Stream
EVs: 252 HP / 252 Atk / 4 Def
Brave Nature (+Atk, -Spd)
- Stone Edge / Rock Slide
- Earthquake
- Crunch​

- Pursuit

604 attack and the ability to almost always attack first... that's something very few can boast about. Stone Edge allows for a great 180 Base STAB, but Rock Slide still is powerful with high attack and STAB, and also allows him to get a flinch rate, which he would love. Although Choice Band gives raw power, I am considering using the Macho Brace, so as to lower my speed to be probably one of the slowest pokemon in OU.​

Octillery (M) @ Expert Belt

Ability: Sniper
EVs: 252 HP / 252 SAtk / 4 SDef
Quiet Nature (+SAtk, -Spd)
- Water Spout
- Surf
- Energy Ball​

- Ice Beam

Octillery is a threatening pokemon. Water Spout will 2HKO most pokemon that even DO resist it. Surf is for when Octillery is not a near-Max health. Energy Ball for Water Types and Ice Beam handles Flying Types.​

Weavile (M) @ Life Orb
Ability: Pressure
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Ice Punch
- Ice Shard
- Night Slash
- Low Kick
Weavile finishes as the Late-Game sweeper. He comes in when all my other pokemon have been taken out, and with them weakened, he can finish the game. Ice Punch is a strong move to use for STAB, and Ice Shard is mostly for pokemon who outspeed me, or if Trick Room time hasn't ended. Night Slash for Psychic Coverage and STAB, Low Kick just in case of Tyranitar.
Possible Changes
Uxie > Smeargle​

Uxie @ Leftovers
Ability: Levitate
EVs: 252 HP / 252 Def / 4 SDef
Relaxed Nature (+Def, -Atk)
- Yawn
- Trick Room
- Reflect
- Thunderbolt
Uxie plays several key differences than Smeargle. It can Defend better, giving it better staying power, and is also a better attacker. It can force switches and get Trick Room out easier overall. Most pokemon in OU use Physical attacks, so Reflect seemed viable. Thunderbolt for Crobat and Aerodactyl.​

Slowbro > Octillery​

Slowbro @ Leftovers
Ability: Own Tempo
EVs: 252 HP / 252 Def / 4 SDef
Relaxed Nature (+Def, -Atk)
- Surf
- Trick Room
- Slack Off
- Psychic
Slowbro is a great defensive pokemon, even in OU. And an actual healing move makes sure Slowbro can keep coming back. Although I lose the great Special Attack, I get more bulk and keep decent special attack, and another Trick Roomer never hurts! Surf and Psychic for the STAB.​

And with the loss of a Special Attacker, I may need this:​

Mixed Tyranitar > Physical Tyranitar​

Tyranitar @ Life Orb
Ability: Sand Stream
EVs: 4 HP / 252 Atk / 252 SAtk
Quiet Nature (+SAtk, -Spd)
- Flamethrower
- Ice Beam
- Crunch
- Superpower
With getting rid of Octillery, I decided to go with Mixed Tyranitar, since I no longer had a devoted Special Attacker. Flamethrow and Ice beam make for a powerful combonation on the special side, Crunch is good for STAB and Superpower is just epic in general.

Three hourse of typing began to hurt my fingers. That's about all there is, so rate away~​

change weavile with excadrill, it sweeps in a sandstorm better

 

[Milking the Tank]

I am somewhat worried about your Smeargle. Some people may mistake for it to be a SporeSub Smeargle, and taunt it right off the bat. Once that has happened, you're forced to switch onto another Trick Roomer in order to get Trick Room up and running. Afterwards, the opponent has the chance to set up entry-hazards or inflict your Pokemon with burn, parahax, or any other status moves.

 

[kmuffinman]

I think you should definitely replace Smeargle with Uxie. Smeargle is too frail and I don't see the roles that it fulfills
Cressilia is prone to taunt. You could replace Lunar Dance with Psychic for an offensive move in case of Taunt

 

[GreasyPanda]

Sorry for the short rate. There not usually this short but I don't know all that much about trickroom to be suggesting things. But I would suggest running choice band on T-tar for brute force. I don't think many pokemon that can OHKO are gonna try and be out slowing you.
