Doubles OU EV Spread Compendium

Concept and OP based on the ORAS OU EV Spread Compendium
Banner by yours truly <3​

Ah EV spreads, great on Pokemon and on toast! But I digress, welcome to the Doubles OU EV Spread Compendium! This is a thread designed to help old and new players alike in choosing the optimal Effort Value spreads and Natures for the most effective Pokemon in Doubles OU.

More often than not, newer players use inefficient EV spreads for their Pokemon. It can vary from just clicking the Suggested Spread button in the teambuilder (which is almost always a terrible spread), or running random EV's to make oneself seem "competitive". A more experienced player may take an EV spread off of the SmogDex. While the QC team is indeed hard at work updating these spreads, Doubles OU is a rapidly changing metagame, and many spreads are no longer as effective as they were in the past.

Here is where our thread comes in. This resource sets out to inform both new and experienced players of the most common or effective EV spreads for top-tier Pokemon, while simultaneously providing a thread where alternative, yet viable EV Spreads and Natures can be discussed.

How Contributing Works
​

In this thread, you may suggest EV Spreads and Natures for all Pokemon on the Doubles OU Viability Rankings. Any Pokemon not ranked will not be added to this compilation, and this compilation will be updated to reflect these rankings. If the Spread and Nature you are suggesting is not standard, you must provide rational reasoning for why these non-standard Spreads are viable and effective. You must also provide as of what the Spread does. Feel free to back your spread up with damage calculations or the speed of the Pokemon you are trying to check and counter. Please, however, do not suggest gimmicky or unviable Spreads in an attempt to create more sets for a Pokemon. Including additional spreads to speed creep these new EV spreads are also discouraged, as speed creeping has to end at some point.

(Note: This thread is for EV Spreads ONLY. You do not need to include a moveset in your post, though you may mention it in the description.)
The point of this thread is to note of effective EV spreads. Unique movesets belong in the Creative Sets thread.

>>Tier 1<<

Aegislash

Bulky Utility
252 HP / 252 SpA / 4 SpD
Quiet or Modest Nature
Max Special Attack has a chance to OHKO Kangaskhan at +2, but otherwise Aegislash doesn't hit any other benchmarks. It typically runs minimum Speed with a Quiet nature to serve as a Trick Room counter.

EVs: 240 HP / 160 SpA / 112 SpD (by meloettaaa)
Quiet Nature
IVs: 7 Spe
Lives a 252+ Choice Specs Hydreigon Dark Pulse, remainder goes into SpA. If you use Weakness Policy you will KO Hydreigon at +2 with Flash Cannon. The 7 IVs are for outspeeding neutral Rhyperior with 31 IVs, however I don't know if that is still as relevant anymore considering Knights of the Sun doesn't exist anymore

Tailwind Attacker (by thetalkingtree)
EVs: 172 HP / 252 SpA / 84 Spe
Modest Nature
Outspeeds positively natured base 110 Speed Pokemon under Tailwind, allowing it to check Mega Diancie, as well as fast Thundurus.

Amoonguss

Bulky Rage Powder
EVs: 252 HP / 172 Def / 84 SpD
Sassy / Relaxed Nature
Survives a Timid Latios' Life Orb boosted Psyshock, as well as a Zen Headbutt from Jolly Metagross if it has a Relaxed nature. Minimum speed allows it to underspeed opponents in Trick Room and Spore them.

EVs: 252 HP / 240 Def / 16 SpD (by KyleCole)
Relaxed Nature
Survives a +1 Reutun from Adamant Mega Kangaskhan, as well as an Ice Beam from Kyurem-B.

EVs: 252 HP / 200 Def / 56 SpD (by KyleCole)
Sassy Nature
This doesn't hit a specific benchmark, but is the most efficient spread for mixed defenses.

EVs: 192 HP / 136 Def / 28 SpA / 152 SpD (by Level 51)
Sassy Nature
Its HP stat is a multiple of 3 to maximize Regenerator recovery. It also survives an Adamant Mega Kangaskhan Double-Edge, and guarantees a 2HKO on Terrakion with Giga Drain.

Mega Charizard Y

Wallbreaker
EVs: 4 Def / 252 SpA / 252 Spe
Modest or Timid Nature
Timid Nature can speed tie with other positive-natured base 100 Speed Pokemon, as well as Jolly Excadrill outside of Sand and maximum Speed Kyurem-B. If outspeeding these are not nessisary, Modest can be used instead

Bulky Special Attacker (all by KyleCole)
EVs: 232 HP / 76 Def / 92 SpA / 108 Spe
Modest Nature
This lives Adamant Mega Kangaskhan Return 100% of the time, outspeeds max speed base 70 Pokemon, with the remainder in Special Attack

EVs: 232 HP / 76 Def / 16 SpA / 184 Spe
Modest Nature
This has the same defensive benchmark as the previous set, outspeeds max speed Adamant Landorus-T, with the remainder in Special Attack. This set works well with Icy Wind support.

EVs: 224 HP / 152 Def / 24 SpA / 108 Spe
Modest Nature
This survives Rock Slide from Adamant Landorus-T 100% of the time, outspeeds max speed base 70 Pokemon, with the remainder in Special Attack.

Trick Room Attacker (by thetalkingtree)
EVs: 232 HP / 76 Def / 88 SpA / 112 SpD
Quiet Nature
IVs: 0 Spe
This allows Zard to avoid the KO from Adamant Mega Kangaskhan's Return or Life Orb Thundurus' Thunderbolt, with the rest dumped into SpA. If you're not worried about Thundurus (this set does pair well with Rhydon after all), or if your team is otherwise really ruined by Amoonguss, you can move the SpD EVs into SpA to guarantee OHKOs on Azumarill, Virizion, Sash Gengar, and Amoonguss.

Mega Diancie

Mixed Attacker
EVs: 208 Atk / 48 SpA / 252 Spe
Hasty Nature
Maximum Speed is required because Diancie needs to outspeed threats like Keldeo and Terrakion, and has crucial speed ties with Latios and Mega Metagross. 48 Special Attack guarantees an OHKO on Bisharp with Earth Power. The rest is put into Attack to power up Diamond Storm. Hasty is used because the lower Defense can be fixed by boosts provided by Diamond Storm.

EVs: 56 Atk / 200 SpA / 252 Spe (by thetalkingtree)
Hasty Nature
Ensure a 2HKO on 4HP Kangaskhan using Moonblast. Hasty is used because the lower Defense can be fixed by boosts provided by Diamond Storm.

Mega Kangaskhan

All-Out Attacker
EVs: 4 HP / 252 Atk / 252 Spe
Adamant or Jolly Nature
This spread doesn't hit any specific benchmarks, but it's designed to go fast and hit hard. Jolly could be used over Adamant to outspeed speed base 90 Pokemon or neutral nature speed base 100 Pokemon, but since Kangaskhan has a ton of priority moves, it isn't completely necessary. Kangaskhan can also exchange it's Speed EVs for HP for more overall bulk.

Trick Room Attacker (by checkmater75)
EVs: 180 HP / 252 Atk / 76 Def
Brave Nature
Maximizes Mega Kangaskhan's Attack while splitting the rest of the EVs between HP and Defense so that Kangaskhan always lives Keldeo's Secret Sword.

EVs: 252 HP / 228 Atk / 28 Def (by shaian)
Brave Nature
Always lives a Secret Sword from Keldeo while maintaining more special bulk.

Keldeo

All-Out Special Attacker
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
Keldeo functions best with max Special Attack to hit opponents super hard. The maximum Speed with a Timid speed ties at worst with other base 108 speed Pokemon like Terrakion and Infernape.

Landorus-T

Choice Scarf
EVs: 4 HP / 252 Atk / 252 Spe
Adamant / Jolly Nature
Max Attack and an Adamant nature for as much damage as possible. The speed investment outspeeds Mega Gengar and Mega Manectric.

Bulky Attacker (by SpaceBass)
EVs: 248 HP / 52 Atk / 116 Def / 92 SpD
Adamant Nature
Survives two -1 Double Edges from Adamant Mega Kangaskhan after Sitrus Berry recovery, Modest Hydreigon's Life Orb-boosted Draco Meteor, Thundurus's Hidden Power Ice without Life Orb, and +1 Adamant Bisharp's Life Orb-boosted Knock Off. This set works great on Semi Trick Room or with Tailwind support.

Life Orb Attacker (by KyleCole)
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
Doesn't do anything specifically, but it hits hard and goes fast. Max Speed is necessary to outspeed neutral base 100 Speed Pokemon like Adamant Mega Kangaskhan. This spread can also work with a Choice Scarf.

Talonflame

Gale Wings Attacker
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
It doesn't require a Jolly nature because it doesn't cause Talonflame to outspeed anything else significant, so Adamant gives it as much Attack as possible. Everything else is to go fast and hit hard.

Mixed Attacker (by Hashtag)
252 Atk / 120 SpA / 136 Spe
Naive Nature
The Special Attack guarantees an OHKO on Mega Metagross with Overheat, with the remainder in Attack to power up Brave Bird.

Choice Band (by thetalkingtree)
EVs: 92 HP / 248 Atk / 168 Spe
Jolly Nature
Outruns max speed base 115s like Raikou and always survives LO Talonflame's Brave Bird.

>>Tier 1.5<<

Bisharp

All-Out Attacker
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
This set doesn't hit any specific benchmarks, simply giving Bisharp as much Attack power as possible. This is by far the most effective Bisharp spread and one shouldn't really deviate from it.

Heatran

Substitute
EVs: 52 HP / 252 SpA / 204 Spe
Modest Nature
Outspeeds neutral base 70 Speed Pokemon, with the remainder in HP.

4 HP / 252 SpA / 252 Spe (by thetalkingtree)
Modest Nature
Outspeed or at least speed-tie with other Heatran.

Trick Room Eruptran (by checkmater75)
EVs: 252 HP / 252 SpA / 4 SpD
Quiet Nature
Maximizes Heatran's Special Attack while putting the rest into HP. Quiet Nature and 0 Speed IVs will ensure Heatran moves first in Trick Room.

Hydreigon

Special Attacker
EVs: 252 SpA / 4 SpD / 252 Spe
Modest or Timid Nature
The EVs don't hit any specific benchmarks, but running a Timid Nature can allow Hydreigon to outspeed neutral-natured base 100 Speed Pokemon. Otherwise, Modest can be used to make Hydreigon to hit as hard as possible.

Bulky Attacker
EVs: 216 HP / 152 SpA / 16 SpD / 124 Spe
Modest Nature
The Special Attack EVs guarentees an OHKO on 44 HP Landorus-T with Draco Meteor, and on OHKO on Mega Metagross with Dark Pulse, and a 2HKO on Cresselia. The Speed EVs outspeed Jolly Breloom. The HP also hits a Life Orb number to minimize Life Orb recoil.

Jirachi

Follow Me Support
EVs: 252 HP / 164 SpD / 92 Spe (by checkmater75)
Jolly Nature
This outspeeds base 80 Speed Pokemon. More speed EVs can be run to creep or to hit benchmarks for opponents at -1 speed if Jirachi is using Icy Wind. The rest is put into HP and SpD to maximize bulk.

252 HP / 52 Def / 96 SpD / 108 Spe (by talkingtree)
Careful Nature
Avoids the 2HKO from Kyurem-B's Earth Power, outspeeds Base 70 Speed Pokemon, with the rest in Defense.

252 HP / 92 Def / 164 SpD (by thetalkingtree)
Impish Nature
Survives a Life Orb Talonflame Flare Blitz with the rest dumped into Special Defense.

Kyurem-B

Substitute
EVs: 100 HP / 252 SpA / 156 Spe
Modest Nature
Maximum Special Attack for as much damage as possible. The Speed outspeeds maximum Speed base 70 Pokemon, while the HP stat maximizes Leftovers recovery.

Mixed Scarf
EVs: 32 Atk / 252 SpA / 224 Spe
Hasty Nature
The Speed investment with Choice Scarf outspeeds Jolly Choice Scarf'd Landorus-T. Maximum Special Attack is to power up Ice Beam, with the rest in Attack.

EVs: 252 Atk / 32 SpA / 224 Spe (by talkingtree)
Naive Nature
Designed to power up Dragon Claw, Kyurem-B's more spammable move.

Latios

All-Out Special Attacker
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
Maximum Speed is required to compete with other base 110 Speed Pokemon, with maximum Special Attack to hit as hard as possible.

Rotom-W

Special Tank
EVs: 252 HP / 100 Def / 116 SpA / 40 SpD
Modest Nature
Survives a Mega Kangaskhan Fake Out and Return, two of Mega Metagross' Zen Headbutt, and two of Amoonguss' Giga Drain. If on a Tailwind team, 12 of the Special Attack EVs should be moved into Speed to outspeed Choice Scarf Landorus-T under Tailwind.

252 HP / 96 Def / 128 SpA / 20 SpD (by thetalkingtree)
Modest Nature
Survives Adamant Mega Kangaskhan's Fake Out + Return combo or Life Orb Latios' Draco Meteor, with the rest in Spcial Attack. 12 EVs can also be moved from Special Attack to Speed if Rotom-W has Tailwind support to outrun Adamant Scarf Lando-T under Tailwind.

Choice Scarf (by SpaceBass)
EVs: 252 HP / 148 SpA / 108 Spe
Modest Nature
Choice Scarf is used with the move Trick to lock the opponent into undesired moves. It's Speed reaches 352 speed to beat max base Speed 110 Pokemon, and burn Mega Kangaskhan and Mega Metagross before they move. The Special Attack OHKOs Mega Diancie. Max HP patches up it's poor base HP.

Choice Specs (by talkingtree)
252 HP / 4 Def / 252 SpA
Quiet Nature
Choice Specs and max Special Attack allow for as much damage output as possible. The remainder is put into HP for more overall bulk. This spread and set should only be used on a Trick Room team with 0 Speed IVs.

Thundurus-I

Bulky Support (by n10sit)
EVs: 252 HP / 84 Def / 16 SpA / 128 SpD / 28 Spe
Bold Nature
This lives a Mega Diancie Diamond Storm, Modest Hydreigon Draco Meteor, and outspeeds base 70 Speed Pokemon.

EVs: 252 HP / 20 Def / 44 SpA / 192 SpD (by Mizuhime)
Calm Nature
"My version of the bulky thundurus that i've always used, forget the specifics so i'm sorry" It's Mizuhime its probably a good spread.

244 HP / 104 Def / 8 SpA / 132 SpD / 20 Spe (by thetalkingtree)
Modest Nature
Avoids the OHKO from Life Orb Modest Hydreigon's Draco Meteor or Stone Edge from Adamant Landorus-T, while outspeeding Breloom and the last 8 put into Special Attack for slightly more power.

Special Attacker (by talkingtree)
EVs: 252 SpA / 4 Def / 252 Spe

Brave Nature

EVs: 240 HP / 224 Atk / 44 Def
Relaxed Nature
A more defensive version, should be used with Rocky Helmet. Avoids the 2HKO from Power Up Punch Adamant Mega Kangaskhan, KOes in return without even clicking an attack due to recoil. Rest in Atk, which means it beats Landorus-T trying to switch in since Gyro Ball 2HKOs at -1 with Iron Barbs

Mega Gardevoir

EVs: 72 HP / 252 Atk / 184 Spe
Adamant Nature
Outruns Base 70 Speed Pokemon, has some decent bulk, and kills lots of things. (Mizu can't remember exactly but it's Mizu so you know its a good set).

>>Tier 2'<<

Mega Abomasnow

Mega Trick Room Attacker
EVs: 252 HP / 4 Atk / 252 SpA
Quiet Nature
HP EVs boost Abomasnow's bulk and 252 Special Attack EVs give Blizzard and Giga Drain maximum power. The 4 spare EVs are placed into Attack to boost the power of Ice Shard. 0 Speed IVs with a Quiet nature ensure that Abomasnow can take full advantage of Trick Room.

Azumarill

Megabus (Belly Drum Attacker)
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
Since Azumarill is using priority Aqua Jet most of the time, it doesn't really need to run Speed. 252 HP also maximizes Azumarill's Sitris Berry recovery.

EVs: 200 HP / 200 Atk / 140 Def (by Pocket)
Adamant Nature
Survives a Choice Band Brave Bird from Talonflame and Explosion from Landorus-T after Belly Drumming.

EVs: 244 HP / 196 Def / 68 SpD
Bold Nature
Lives a Modest Aegislash Flash Cannon 100% of the time, with the remainder in Defense. The Defense also lives a Life Orb Bisharp Iron Head 87.5% of the time.

EVs: 252 HP / 200 Def / 56 SpD
Calm Nature
Does not hit a specific benchmark but is the most efficient spread for mixed defenses.

Cresselia

Calm Mind
EVs: 252 HP / 252 Def / 4 SpD
Bold / Relaxed Nature
Calm Mind boosts Cresselia Special Defense, so maximum HP and Defense is run instead to make Cresselia as bulky as possible.

Bulky Support
EVs: 252 HP / 100 Def / 44 SpA / 112 SpD
Calm Nature
With Sitrus Berry, it survives a Shadow Ball from Modest Mega Gengar and Double-Edge from Mega Kangaskhan.

EVs: 252 HP / 100 Def / 44 SpA / 112 SpD (by meloettaaa)
Calm Nature
IVs: 0 Speed
Avoids getting 2HKOd by 252+ Mega-Gengar Shadow Ball, and avoids getting 2HKOd by 252+ Mega-Kangaskhan Double-Edge.

Hoopa-U

Tailwind Attacker
EVs: 252 Atk / 140 SpA / 116 Spe
Rash Nature
The Special Attack investment with a boosting Nature and Life Orb will OHKO 76+ SpD Amoonguss with Hyperspace Hole. Max Attack is to boost the power of Hyperspace Fury. The Speed also outspeeds base 110 Speed Pokemon under Tailwind.

EVs: 128 Atk / 204 SpA / 176 Spe (by Arcticblast)
Hasty Nature
Guarantees an OHKO on standard Sassy Amoonguss with Life Orb boosted Hyperspace Hole. 176 Speed Hasty puts it above base 70 Speed Pokemon and things creeping them by one (base 80 Speed Pokemon hit a jump point here). 128 is the "dump" stat but you OHKO Aegislash with Hyperspace Fury anyways.

Bulky Attacker (by astroboy)

[megacyber]

Is this really necessary? Like, between the doubles ou c&c thread, and the smogdex, you can get a decent spread for p much anything that isnt super obscure.

 

[n10siT]

The smogdex has some pretty outdated/bad spreads imo.

http://www.smogon.com/dex/xy/pokemon/deoxys-attack/doubles/ - doesn't outspeed lando-t
http://www.smogon.com/dex/xy/pokemon/heatran/doubles/ - nobody runs this slow of a sub set
http://www.smogon.com/dex/xy/pokemon/kyurem-black/doubles/ - nobody runs this slow of a sub set, and certainly nobody runs no speed

 

[Arcticblast]

You can't slash EV spreads on analyses

 

[megacyber]

Can't you put alternate spreads in other options?

[Checkmater]

I love this thread because it's just so annoying to go to /analysis rotom-wash, figure out what janky spread people use, then import it. If this thread picks up with 1-3 and maybe even beyond it could be so much more convenient, and also there are loads of spreads not in the analysis thread

also 10/10 art I love it

anyways here's an amoonguss spread


252 HP 76 Def 180+Spdef
252 SpA Mega Charizard Y Heat Wave vs. 252 HP / 180+ SpD Amoonguss in Sun: 360-426 (83.3 - 98.6%) -- guaranteed 2HKO

It's hard to pick between spdef and def because you don't really know if opponents are using psychic or psyshock, but living zard y heat waves and being able to tank heatran heat waves is pretty nice. Running so much spdef can leave you rather open to kang though

Also for Diancie:

252 Atk 4 SpA 252 Spe Naive/Hasty

Maximize your diamond storm damage, you don't really need those 44 spA evs (you still ohko heatran and moonblast still gets its kos). The benchmark that's set at is actually to ohko bisharp, but I like this spread more because:

1) bisharp is sash or lo. It's unlikely you'll get into a situation against a life orb bisharp where it hasn't taken any recoil yet, in conjunction with you losing what is a 96% roll with 4 SpA. And if it hasn't taken recoil are you really going to be ballsy enough to risk that?
2) You're clicking diamond storm around 80% of the time, and you want more damage on your main STAB
3) Various bulky thundurus/togekiss/gyarados/zap sets are ev'ed exactly to live diamond storm, this gives you around a 4% chance to get a ko on said sets

Anyways it's a small deviation from the standard diancie set but better imo

 

[Checkmater]

Jirachi Spread:

EVs: 252 HP / 164 SpD / 92 Spe
Jolly Nature

Outspeeds base 80s such as HoopaU. More speed can be run to creep or to hit benchmarks for opponents at -1 speed if using icy wind. Rest is put into HP and Spdef to maximize bulk

Modest Nature

ty to Isa for helping to make spread less shit/more efficient

I included the set here because the spread involves sitrus berry

-Lives earthquake from max adamant lando t, if you are using HP ice you need 112 EV's in def, take 4 from spa
-Gets 3HKO'd by max spa Kyube earth power after sitrus: 252+ SpA Teravolt Kyurem-B Earth Power vs. 240 HP / 12 SpD Raikou: 202-238 (53 - 62.4%) -- guaranteed 2HKO (100%-62.4%=37.6%,37.6%+25%=62.6%), does the same thing against standard 48 spa mega diancie
-Outruns adamant Kang and other max invested base 100's without boosting nature
-Rest into special attack
-Note it cannot OHKO Lando with HP ice so dont leave it in on a lando with full health

 

[shaian]

that set looks hella inefficient, amongst other things I'm not sure why you gave up speed / power for the spd when raikou can't touch kyube.

 

[n10siT]

that set looks hella inefficient, amongst other things I'm not sure why you gave up speed / power for the spd when raikou can't touch kyube.

if there's a more efficient way to do what it does please correct it but i was using this set as t bolt/snarl/roar bc i didnt have a tr stopper and it also beats sub users

 

[Isa]

without commenting on whether the heavy commitment to defenses is worth it here's a more efficient spread for you

252 Atk Mew Crunch vs. 248 HP / 44+ Def Raikou: 80-95 (20.8 - 24.8%) -- guaranteed 5HKO
252 SpA Mew Shadow Ball vs. 248 HP / 44 SpD Raikou: 70-83 (18.2 - 21.6%) -- possible 5HKO

252 Atk Mew Crunch vs. 96 HP / 120+ Def Raikou: 73-87 (21.1 - 25.2%) -- 0.1% chance to 4HKO
252 SpA Mew Shadow Ball vs. 96 HP / 120 SpD Raikou: 65-77 (18.8 - 22.3%) -- possible 5HKO

same amount of EVs used

 

[n10siT]

Ty :) i adjusted the numbers some and changed from bold to modest, since i can hit the same physical defense benchmark while getting 7 more stat points in special attack
