(21:31:42) *** Your rank in Standard OU is 14/57802 [1494 points / 146 battles]!
Yup. Nobody saw it coming. Yanmega in OU? Where priority in the form of Scizor, stealth rocks, sandstorm, and Chansey running amok, how could Yanmega possibly function? Well, through heavy team support, Yanmega is actually a potent threat.
Peaking #14, I would say this team has something going for it. However since then, I haven't been able to top that. In fact, I've been hovering in the mid 1300's. This team admittedly has problems, which is where you guys come in. So, onto an in-depth look at the team.

Yanmega. The MVP of the team. Great dual stab coverage, almost unable to be beaten speed-wise without priority, good power with a life orb, and a third coverage move? Unstoppable if the 1 or 2 counters are taken out.

Next up, Forretress. Almost a no brainer, this guy can set up spikes to help secure crucial KOs, rapid spin stealth rocks for Yanmega, all the while gaining offensive momentum with volt switch and not being set-up fodder to dragons with Gyro Ball. I chose to forgo Toxic Spikes, since my team is more offensive and poison damage is pretty useless.

Most people assume that I only have 1 spinner, therefore Starmie is choiced.
This starmie acts as both a lure, and a surprise spinner. After my Forretress has died, they set up all their hazards then suicide their Ferrothorn; that's when Starmie comes in and gets rid of all the hazards a second time. He also provides strong Water/Ice/Electric attacks coming from a high speed, so he's a threat on his own.

Yet another Pokemon to make keeping SR up on my side of the field difficult (or in this case not up at all!) Magic bounce ensures that at the worst, I lose my Espeon while keeping my field free of hazards. Espeon also has the bonus of countering Brelooms (along with possibly bouncing Spore back on an un-activated Toxic Orb Breloom!) Contains CM to be a threat & a supporter at the same time. Couple that with Baton Pass, he has a psuedo volt-turn with Forre and can even pass +Sp.Atks to Yanmega.

Providing SR, a MUCH needed immunity to fire, a strong Fire attack to hit those that try to set up hazards (Skarmory/Forre/Ferro), while keeping Heatrans at bay with Air Balloon+Earth Power, Heatran supports the teams in too many ways. A perfect fit for the team.

I thought long and hard about the last slot (not really). I needed a strong fighting type, because my team would get dumped on by Chansey/Blissey. Real talk. I was contemplating Shed Skin Scrafty, Sub Toxicroak, and Conkeldurr. In the end, the ability to grab a guts boost, provide a strong priority in Mach Punch, and enough bulk to switch in multiple times, Conkeldurr just seemed like the better "Fat Kirby" counter.
Now, onto the individuals.
An In-Depth Look

Big. Threat. (Yanmega) (F) @ Life Orb
Trait: Speed Boost
EVs: 4 Def / 252 SAtk / 252 Spd
Modest Nature (+SAtk, -Atk)
- Protect
- Bug Buzz
- Air Slash
- Hidden Power [Ground]

This set has everything it needs to succeed. Dual stab, Air Slash with some clutch flinch hax if needed, Bug Buzz for powerful stab & coverage. HP Ground because Heatran is way too common. HP Fire is not needed as much, Air Slash
is both powerful and can still flinch anyways. Modest for more power & since I'm confident with my ability to get 1+ Speed Boosts. Life Orb for much-needed power.

Robert Forre (Forretress) (F) @ Leftovers
Trait: Sturdy
EVs: 252 HP / 176 Def / 80 SDef
Relaxed Nature (+Def, -Spd)
- Spikes
- Rapid Spin
- Volt Switch
- Gyro Ball

Standard defensive set, but who says it doesn't work? Of course it does. Has the ability to revenge kill Terrakion, or switch into any 2 attacks and retaliate.
Providing hazards, spin support, and offensive pressure while retaining great bulk, Forretress does what only it can do for this team.

The Dome! (Starmie) @ Expert Belt
Trait: Natural Cure
EVs: 4 HP / 252 SAtk / 252 Spd
Timid Nature (+Spd, -Atk)
- Thunderbolt
- Ice Beam
- Rapid Spin
- Surf

Providing reliable water stab, Starmie serves both as a backup last resort spinner, spinblocking counter, Gliscor, Gyarados, and Dragon slayer. Expert Belt to provide almost the same amount of power, bluff the choice item, and not lose HP as I rapid spin. Also provides a much needed water resistance.

On Like Espe (Espeon) (M) @ Leftovers
Trait: Magic Bounce
EVs: 252 HP / 4 SAtk / 252 Spd
Timid Nature (+Spd, -Atk)

Hey, maybe I don't need my Forretress for spikes this time around. Maybe I can use Blissey as set up fodder. This guy does it all. A lot of people expect Espeon to go down in about 4 Seismic tosses from their Fat Kirbys; then, I baton pass out to Yanmega, get 2 speed boosts on the switch and protect, and suddenly they're faced with a game-ending sweep. Espeon can still pose a threat with HP Fighting and Stored Power (+1 HP Fighting has a 68% chance to 1hko 252hp Tyranitar after 1 layer of spikes and SR).

Tran Tracks (Heatran) (F) @ Air Balloon
Trait: Flash Fire
EVs: 252 SAtk / 4 SDef / 252 Spd
Modest Nature (+SAtk, -Atk)
- Fire Blast
- Earth Power
- Stealth Rock
- Hidden Power [Ice]

Roasting steel types (including the ubiquitous Skarmory that counters my Yanmega) that tend to set up hazards, Heatran is here to set up quick SR, while not being a total duck. Fire Blast with Modest 252 hurts anything, including resisters. Unlike the Specially Defensive set, this one trades more reliable SR for the ability to nab KOs. Coupled with Air Balloon, a lot of teams don't have any option but to sacrifice a poke just to break my Balloon.

Conkelderp (Conkeldurr) (M) @ Choice Band
Trait: Guts
EVs: 252 HP / 252 Atk / 4 Spd
Adamant Nature (+Atk, -SAtk)
- Superpower
- Mach Punch

Switch on the Blissey Twave/Toxic, and they're pretty much done. I did 52% to 4 Def Latios with Superpower. I didn't even have to risk the prediction. Nothing can switch into this thing after a guts boost. With a guts boost, Conkeldurr's Mach Punch is actually more powerful (and with better coverage) than Scizor's Bullet Punch. Stone Edge and Payback to round out the coverage. His bulk ain't bad either, he can survive a LO Latios' Draco Meteor 46% of the time.
Conclusion
The point of this team isn't to make sure all the conditions are right for Yanmega to sweep. It'd be nice if that were the case, but sometimes Yanmega isn't even needed. Hey, if the opponent has 6 pokes with SR, nothing I can do about it. It's gonna get up. Some rounds are like that. But every single pokemon is a potent offensive threat on their own, while each supporting each other in some small way, and all 5 pokes collectively support Yanmega. If Yanmega is a big threat to their team, my opponents will more often than not, overly focus on SR. The rest of my pokemon aren't affected by SR much at all, so I can just wallbreak. Yanmega isn't the only trick up my sleeve, and that's what makes this team so powerful.

Thanks for taking time to read this RMT, and I hope you guys take the time to
improve/change up my team for the better. I want to reach higher on the ladder, and I think this team is my best (and most fun) option to do so.
