I don’t like to bother with fancy intros, so I’ll just cut to the chase. I will say that the scope of my testing is relatively limited; I played quite a few games with this team, but all I got were gimmick teams (e.g. Steel Wing Latios to eliminate Mega Diancie) or Mega Manectric teams (my elo when testing was around 1400; I wish I could go higher but I had obligations to take of in real life); thus, my analysis may be a bit unreilable..
Anyways, onto the team.
And before you read, please forgive any inconsistencies, grammar mistakes, rushedness, or even spelling errors you find; note I wrote this very quickly. I will likely go back and fix it if I have the time.
Teambuilding
Started with Diancie as the Mega. Deals a ton of damage, but often falls short of OHKOing if the attack isn’t super effective and the target is healthy/bulky enough. Often has to go mixed, but it’s not an enormous problem.
Followed up with Kyurem-Black as a wallbreaker, and has the added bonus of performing relatively well against stuff like Venusaur, Landorus-Therian, Garchomp, etc. Scarfed variants still pose a problem.
Rotom-Wash absorbs Bullet Punches, Meteor Mashes and the like, then burns perpetrators. Diancie and Kyurem-B has a shared Steel weakness, and Rotom-Wash definitely helps. Second check to Ground-types.
Scizor is a relatively good check to Weavile, and to a lesser extent Tyranitar. Is the revenge killer and secondary component of VoltTurn.*
Skarmory is the physical wall and stands up to things like Mega Lopunny, Diggersby, Excadrill, etc. However, it can do little to retaliate against Excadrill, as it resists Brave Bird. Still a good wall and can stack Spikes and Defog.†
Heatran is the special wall and the only solid check to Serperior I have. Sets up Rocks and fishes for burns with Lava Plume.††

* I am aware that I could replace Scizor with things like Choice Scarf Keldeo/Terrakion, Azumarill, and Diggersby. However, Keldeo and Azumarill compound my Mega Manectric weakness, Terrakion compounds my Ground and Fighting-weakness, and Diggersby is too frail.
† I am aware that Defog and Spikes are somewhat counterproductive, but I couldn’t really find a place to put Starmie, Excadrill, Tentacruel, or other Rapid Spin users.
†† I would put Celebi somewhere on this team so that the team can withstand rain offense better, but I can't find a good teammate to replace except for maybe Heatran. However, that doesn't save Celebi from Flamethrower.

Team descriptions
Rock Candy (Diancie) @ Diancite
Ability: Clear Body
EVs: 32 Atk / 224 SpA / 252 Spe
Naive Nature
- Moonblast
- Diamond Storm
- Earth Power
- Protect
Diancie is a solid check to non-Iron Tail Tornadus-Therian and non-Steel Wing Talonflame. OU isn’t very nice to Diancie, as the heavy usage of Steel-, Ground-, and Water-types, as well as Serperior, all threaten Diancie’s life. Still manages to deal truckloads of damage whenever it can and can KO weakened foes. Diancie, however, usually won’t OHKO unless the enemy is weak to the move or is not healthy/bulky enough to withstand the attack. The enemy will still be wounded badly, though – usually.
Mr. Freeze (Kyurem-Black) @ Life Orb
Ability: Teravolt
EVs: 20 Atk / 252 SpA / 236 Spe
Mild Nature
- Ice Beam
- Earth Power
- Fusion Bolt
- Roost
Kyurem-Black is a fairly solid wallbreaker, and can usually address the foes Diancie has problems with – Landorus-Therian, Garchomp, Amoonguss, Rotom-Wash, and Mega Venusaur are all targets for Kyurem-Black. Even then, it’s not a sure check, as Landorus-Therian and Garchomp usually carry Choice Scarves, Mega Venusaur usually withstands a single Ice Beam and can use Sleep Powder or Leech Seed, and Rotom-Wash can take an Earth Power and Will-O-Wisp Kyurem-Black, effectively neutering him. This is also one of two allies on my team that can take on Mega Manectric.
iWashU (Rotom-Wash) @ Leftovers
Ability: Levitate
EVs: 248 HP / 252 Def / 8 Spe
Bold Nature
- Volt Switch
- Hydro Pump
- Will-O-Wisp
- Pain Split
Rotom-Wash is a solid check to the Steel-types like (Mega) Scizor, and Sand Rush Excadrill. It also handles (Mega) Metagross somewhat well, though Metagross will still pummel Rotom-Wash with its coverage moves. Though it addresses my Steel-type issue somewhat well, it only compounds my Serperior weakness, and does nothing to assist against Weavile.
Claws4Alarm (Scizor) @ Choice Band
Ability: Technician
EVs: 248 HP / 252 Atk / 8 SpD
Adamant Nature
- Bullet Punch
- U-turn
- Superpower
- Pursuit
Scizor is the revenge killer, and forms a shaky VoltTurn duo with Rotom-Wash. It is my only reliable Ice-type check and only reliable check against opposing Fairy-types, namely enemy Mega Diancie, who usually has Earth Power to eliminate Heatran. Also has the benefit of Pursuit-trapping mons like Slowbro, Starmie, and Lati@s, which can really f### with this team otherwise. Note that Scizor still takes a bit of damage switching into special attacks, as it loses around 35% average from Hyper Voice, Moonblast and the like.
Skarmory @ Leftovers
Ability: Sturdy
EVs: 252 HP / 252 Def / 4 SpD
Impish Nature
- Roost
- Defog
- Brave Bird
- Whirlwind
Skarmory is a physical wall and secondary Steel-type check. It’s the only true counter I have to Choice Scarf Mold Breaker Excadrill. It stacks Spikes, defogs away Toxic Spikes and Stealth Rock (Kyurem-Black is weak to it), and is my only Mega Lopunny check. It also walls non-Hidden Power Fire Serperior.
Heatran @ Leftovers
Ability: Flash Fire
EVs: 252 HP / 188 SpD / 68 Spe
Calm Nature
- Lava Plume
- Toxic
- Taunt
- Stealth Rock
Heatran is my only true check to Sylveon – Scizor takes a lot of damage from resisted Hyper Voice, and my only half-check to Mega Gardevoir (Mega Gardevoir has Focus Blast to deal with Heatran) – again Scizor has difficulty taking a Hyper Voice. It walls non-Hidden Power Ground Mega Pidgeot, non-Earthquake Mega Venusaur, non-Hidden Power Ground Serperior, and non-Focus Blast Tornadus-T nicely. It sets up Stealth Rock and lets Skarmory set up Spikes.
Threatlist
Before you read: yes, I am aware I went a little overkill with the threatlist. It's just that I feel these are legitimate threats, even if the others can be handled with some careful playing. The threats marked with a * are ones I feel are particularly threatening.
EVERY team I make seems to be threatened by this guy. (Please ban to Ubers, as Hoopa looks like a Kitkat compared to this guy. Nah, I’m just joking.) Mega Manectric is only partly checked by Heatran and Kyurem-Black, and they are shaky checks, as they still take a beating from him. As if that wasn't enough, this guy never sits still, as it won't hesitate to Volt Switch all over the f###ing place. To top it off, this guy is lightning fast, and if Heatran and Kyurem-Black go down, the rest of my team will take massive damage or get swept.
*
Lopunny can walk all over this team, as it can wear down Skarmory with High Jump Kick (it does 44% tops) and Skarmory is in danger of being KOed if it uses Brave Bird and Lopunny survives (Lopunny only takes 98% damage from Brave Bird max).
*
Keldeo can also walk all over this team, as it can OHKO Skarmory with Hydro Pump. Rotom-Wash is the only one that can even come close to walling, and even then it risks a Scald burn or getting a Secret Sword to the face – it takes a ton of damage switching in. Diancie can OHKO non-Choice Scarf variants if they didn’t use Calm Mind too many times, though Diancie is a shaky check because if Keldeo lives for whatever reason, it can hit back with a Scald.
Azumarill can deal some serious damage to Skarmory with Choice Band/Belly Drum Waterfall, and it can survive a Fusion Bolt (it takes 94% minimum from Fusion Bolt) and OHKO Kyurem-Black with a Play Rough or Superpower. It can also survive a Bullet Punch from Scizor and hit back with Waterfall or Aqua Jet. Azumarill also reks Diancie. It becomes so much worse if it pulls off a Belly Drum – at least Kyurem-Black can kill it if he's healthy enough to survive an Aqua Jet. This thing is Satan, cancer, whatever you want to call it.
Clefable could survive a Bullet Punch from Scizor and hit back with Flamethrower. To make matters worse, Scizor is the only member of the team that can hit it super effectively; otherwise, it can take beatings from Diancie, Kyurem-Black, Rotom, etc. and just use Moonblast on all of them.
Breloom can do massive damage to Diancie with a Mach Punch before going down to Moonblast. If Diancie cannot counter it, then the rest of my team won’t like eating a Spore. The only other team member that can go somewhat head-to-head with Breloom is Scizor.
Weavile still poses a threat, as Scizor and Skarmory are the only reliable counters to it. Weavile can potentially Knock Off Skarmory and Scizor to death and then deal heavy damage to Diancie with Icicle Crash (and potentially flinch Diancie as well), and Low Kick anyone else.
People like to run gimmick Mew sets, meaning that it could surprise Diancie with an Iron Head or Heatran with an Earthquake. It's hard to tell what Mew will do.
The aforementioned Sylveon and Mega Gardevoir are checked by only Heatran and Scizor; the other teammates take heavy beatings from a Hyper Voice. Mega Gardevoir could even survive a Diamond Storm from Diancie.
*
I didn't find a rain offense team during my testing, but I speculate that rain offense teams also are a big deal, as Rotom-W is the only one capable of withstanding Mega Swampert's or Kingdra's assault. Politoed is just annoying in general.
with a Choice Scarf*
I don't have a hard counter per se to Landorus-Therian equipped with a Choice Scarf, as it can use its coverage moves to maul whoever I send in. It's mostly just a matter of revenging it or predicting what it will do, which I don't like to do; however, with this team, it's really my only option.
*
All this thing needs is the slightest invitation to use Tail Glow, and then my team is toast: I usually have to sac 2 mons to take it down. However, because I don't have anyone that can outspeed it (besides Diancie), it can fire off more moves before going down. Its also fairly durable, being able to take a Fusion Bolt or Volt Switch. Similar case for Volcarona, except that Heatran can wall it nicely – usually.
Well, feel free to revise my team as you see fit. Any feedback is appreciated.
Anyways, onto the team.
