It's been a while since I've made one of these, havn't been too active lately, most of my playing has been on the PO ladder. I made this team a while ago, and it has performed very consistently (although to be honest I'm not sure why). I guess it would classify under semistall, since that's how I usually end up playing with it. Most of the members are somewhat slow, but bulky. So, here is the team.
Quick Glance
Not really any special order, but this is how the team is arranged.






In Depth

Gyarados (M) @ Leftovers Trait: Intimidate
EVs: 252 HP / 100 Def / 156 SDef
Impish Nature (+Def, -SAtk)
- Waterfall
- Roar
- Rest
- Sleep Talk
Resttalk Gyarados. It functions as my counter to so many things, including Breloom, Blaziken, most water types (like Azumarill), most fire types (like Hihidaruma), check Rankurusu, and so on. Originally I had a Rankurusu in this spot, as I needed a Fighting resist who had some semblance of offensive power. However, Rankurusu despite being a beast wasn't working as a teammate as well, so I switched to something I've been using since the start of BW, Resttalk Gyara. Originally I had been really excited for Dragon Tail but I use Roar instead, as a better hard counter to Breloom (and subbers in general) and to avoid the inaccuracy problem. Gyarados is such a valuable member of the team, and has walled and stalled for many a battle.
The EVs aren't standard for Resttalk Gyarados, there is am emphasis on Defense, though I had special defense EVs since Gyarados was often my last check to opposing Rankurusu. If anyone wants to suggest a more efficient spread go ahead.

Randorosu (M) @ Leftovers
Trait: Sand Power
EVs: 4 HP/ 252 Atk / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Earthquake
- Stone Edge
- U-turn
- Brick Break
Originally I had toyed around with Borutorusu as my preferred Genie, with MH Nasty Plot + Thunder Wave, but as I want more pure power I went with Randorusu. Randorusu used to have a bulkier 252 HP / 4 Atk / 252 Spd buky set to deal with Doryuuzu, then a mixed Rock Polish HP Ice set, but I decided that I needed more raw power behind his attacks, as a better way to deal with Calm Minders. He is unfortunately somewhat fragile, but that isn't really what I care about when I use Randorusu. He provides a nice Ground and Electric immunity, with a Fighting resist in a pinch. His 101 base speed is also nice, being able to check Salamence/Jirachi/Celebi/Insert other base 100 with the appropriate move.
Randorusu's initial purpose was to be a Dory check, and still accomplishes that. I always stick Brick Break on my Doryuuzus to deal with opposing Balloon Dorys, and I do the same with this Landlos. Why 2HKO with MissEdge and Earthquake when you can just OHKO with Brick Break?
The EVs are simple, max attack max speed, with Leftovers for bulk.

Bronzong @ Leftovers
Trait: Levitate
EVs: 252 HP / 252 Atk / 4 SpD
Brave Nature (+Atk, -Spd)
- Trick Room
- Earthquake
- Gyro Ball
- Zen Headbutt
The oddest member of my team. TRZong is so good. I saw it in a warstory and had to try it out. TRzong checks so many things its not even funny, especially Ononokusu and Doryuuzu, and checks threats like Gengar. Switch in on the setup, TR and go. Trick Room also actually had great synergy with the rest of the team, while not specifically a Trick Room team, used to have Rankurusu, Nattorei, Bronzong, and -Spe TTar. So Trick Room actually worked great, allowing Nattorei to get hazards before they went and for Rankurusu to get some nice Calm Minds.
The moveset is simple, maximum coverage and Trickroom, and the EVs are also simple. Maximum bulk, maximum attack.

Tyranitar (M) @ Leftovers
Trait: Sand Stream
EVs: 252 HP / 188 SAtk / 68 Spd
Mild Nature (+SAtk, -Def)
- Stealth Rock
- Flamethrower
- Crunch
- Superpower
Tyranitar is a beast. One of my favorites since its creation, it has proven a valuable part of my team. While my team is not specifically a sand team, the sand proves useful, for example sand = no sun, good stuff. Tyranitar is another mon which I have used since the beginning of G5, for its consistent ability to set up Stealth Rock, and maintaining an offensive balance.
This tyranitar used to be Tyranitar@Lum Berry 252 HP/68 SpA/188 SpA Quiet (or whatever +SpA/-Spe was) with Stealth Rock, Flamethrower, Pursuit, and Superpower. And before that max attack max hp with SR Fire Punch Stone Edge Earthquake. However, I find this superior: without the same imminent threat of Rain I can now put investment into speed, to nail Scizors.
The moveset is simple, Stealth Rock since that has always been its purpose. Flamethower to hit Nattorei and Skarmory without Iron Barb Damage/hitting the higher defense. Crunch to handle Rankurusu better. And Superpower as a superior option against Blissey Tyranitar and P2. Leftovers over Lum because I decided extra staying power was more worth it.

Nattorei (M) @ Leftovers
Trait: Iron Barbs
EVs: 252 HP / 120 Def / 136 SDef
Careful Nature (+SDef, -SAtk)
- Power Whip
- Spikes
- Thunder Wave
- Leech Seed
There is a reason Nattorei rocks, awesome resistance and excellent movepool. Nattorei is very valuable to the team, being able to set up Spikes to add residual damage (excellent synergy with Gyarados) and to fire off Thunder Waves, bringing other faster teams to around my level. Usually that is the first move I hit.
For the other two moves I picked Leech Seed, for more residual damage and recovery, and Power Whip, because Gyro Ball doesn't really work on paralyzed targets. It also handles the water types Nattorei often switches into better.

Latios (M) @ Life Orb
Trait: Levitate
EVs: 252 SAtk / 4 SDef / 252 Spd
Timid Nature (+Spd, -Atk)
- Recover
- Hidden Power [Fire]
- Psycho Shock
- Draco Meteor
Latios is the main powerhouse of this team, being able to come in on its many resistances or after a faint, and being able to fire off LO Draco Meteors and run. He is also the fastest member of my team, and my main check to Fighting types, who would otherwise do well against this team.
The moveset is simple, Draco Meteor for STAB, HP Fire to handle Steels (NATTOREI) and Psycho Shock for STAB that hits Fighting types for super effective.
So that's the team, rate/hate/steal. I am at about 1300 on the PO server, and going to start transitioning into the Smogon server. This team I find has excellent synergy, and if I play well very good staying power. Often I can stall out my opponent, for example once with my Gyarados Nattorei core I stalled out a 4-6 into a 3-0. And I had sacked my 3rd faint at 4-1 because I'd rather have the free switch.
