K 2nd 3 mon core of the week right here

Latias @ Latiasite
Ability: Levitate
EVs: 248 HP / 68 Def / 192 Spe
Timid Nature
- Thunder Wave
- Ice Beam
- Recover
- Thunderbolt

Infernape @ Leftovers
Ability: Blaze
EVs: 248 HP / 88 Def / 124 SpD / 48 Spe
Jolly Nature
- Will-O-Wisp
- Slack Off
- Taunt / Encore
- Low Kick

Hippowdon @ Leftovers
Ability: Sand Stream
EVs: 252 HP / 144 Def / 112 SpD
Impish Nature
- Earthquake
- Stealth Rock
- Slack Off
- Stone Edge

Mega Latias is a nice wall-y utility mon. Look at that bulk, walling Zard Y and Lopunny and so on. Anyway Infernape is there to help it deal with Dark types and Scizor and stallbreak a bit (saw Encore on a team once so seemed slash-able to lock mons into stuff like SD or whatever). Hippowdon prevents Volt Switching, helps with Talonflame, ZardX, Excadrill and sets up Stealth Rock, while the others handle most of its weaknesses well.

Altaria-Mega
EVs : 248 HPs / 148+ Def / 112 Spe (to outspeed Mega Aero at +2)
- Return
- Heal Bell
- Roost
- Dragon Dance

Altaria can set up on Hippodown and get +6 if he wants
(0 Atk Hippowdon Earthquake vs. 248 HP / 148+ Def Mega Altaria: 87-103 (24.6 - 29.1%) -- 0% chance to 3HKO after sandstorm damage) even a EQ crit can't 2HKO.
If the opponent want to switch into Infernape or Mega Tias , Altaria with this spread outspeed Mega Tias at +1 and can kill everything.
+1 0 Atk Pixilate Mega Altaria Return vs. 248 HP / 68 Def Mega Latias: 374-444 (103 - 122.3%) -- guaranteed OHKO (he can even get +1 on this if dragon dance on twave and then heal bell or take one ice beam)
+6 0 Atk Pixilate Mega Altaria Return vs. 252 HP / 144+ Def Hippowdon: 433-510 (103 - 121.4%) -- guaranteed OHKO
+1 0 Atk Pixilate Mega Altaria Return vs. 248 HP / 88 Def Infernape: 274-324 (77.1 - 91.2%) -- guaranteed 2HKO (even if he burns after this you can heal bell and then win)

Offensive DD can work too but it will struggle more to set up on Hippo.

SpAttacker Scarf Hoopa-U

Hoopa-Unbound @ Choice Scarf
Ability: Magician
EVs: 252 SpA / 4 SpD / 252 Spe
Modest Nature
IVs: 0 Atk
- Focus Blast
- Grass Knot
- Psychic
- Dark Pulse

Choice Scarf allows this powerhouse to outspeed and KO this fast Defensive Infernape:
252+ SpA Hoopa Unbound Psychic vs. 248 HP / 124 SpD Infernape: 446-528 (125.6 - 148.7%) -- guaranteed OHKO

The same happens to Hippodown with little prior damage to ensure the KO:
252+ SpA Hoopa Unbound Grass Knot (120 BP) vs. 252 HP / 112 SpD Hippowdon: 398-470 (94.7 - 111.9%) -- 68.8% chance to OHKO

252+ SpA Hoopa Unbound Dark Pulse vs. 248 HP / 0 SpD Mega Latias: 248-294 (68.3 - 80.9%) -- guaranteed 2HKO

(fun fact: a fast Dark Pulse can make Mega Latias flinch leading us to a clean kill)​

While Latias do this:
0 SpA Mega Latias Thunderbolt/Ice Beam vs. 0 HP / 4 SpD Hoopa Unbound: 69-82 (22.9 - 27.2%) -- 54.8% chance to 4HKO
If Mega Latias uses Thunder Wave it might win but it's difficult.

===> Hoopa-U is crazily strong because sweeps this core almost with no further help.

 

[Infernal]

Sableye @ Sablenite
Ability: Magic Bounce
EVs: 248 HP / 164 Def / 96 SpD
Careful Nature
- Calm Mind
- Shadow Ball
- Recover
- Will-O-Wisp

Mega Sableye is so effective against this core because of how well it shuts down some of the main roles each member has. Hippowdon can't SR. Infernape can't spread burns and is completely walled, while Mega Latias can't freely paralyze things with Thunder Wave. With all of these roles invalidated, teams looking to use this core have to ensure they cover Mega Sableye well to avoid being helpless.

The above aside, Mega Sableye can CM up to +6 with ease against any core member since none of them are capable of dealing significant damage to it. From there, you can Shadow Ball to victory. If you dislike CM Mega Sableye and would prefer using a different set, variants with Will-O-Wisp / Toxic / Recover / Knock Off perform equally as well versus this core by slowly whittling each member down with poison.

Latios @ Life Orb
Ability: Levitate
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Draco Meteor
- Psyshock
- Calm Mind
- Roost

Once Latios sets up a Calm Mind, which is easy to do against Infernape and Hippowdon (who lacks Whirlwind and is thus set-up fodder), the core drops like a fly against boosted Draco Meteors and Psyshocks. The only Pokemon Latios doesn't want to set up against is his sister, since it fears paralysis, but even then Latios is free to click Draco Meteor against is to secure the OHKO.

Hide

+1 252 SpA Life Orb Latios Draco Meteor vs. 252 HP / 112 SpD Hippowdon: 469-554 (111.6 - 131.9%) -- guaranteed OHKO

Azumarill @ Assault Vest
Ability: Huge Power
EVs: 240 HP / 252 Atk / 16 SpD
Adamant Nature
- Play Rough
- Waterfall
- Aqua Jet
- Knock Off

Nothing can switch into this thing. Assault Vest Azumarill can tank any hit (bar WoW from Infernape, which it should be wary of) from this core, including Thunderbolt from Mega Latias (which is a 3HKO), and 2HKO (or OHKO with a bit of prior damage) every Pokemon in this core.

252+ Atk Huge Power Azumarill Play Rough vs. 248 HP / 68 Def Mega Latias: 288-342 (79.3 - 94.2%) -- guaranteed 2HKO
252+ Atk Huge Power Azumarill Waterfall vs. 252 HP / 144+ Def Hippowdon: 222-264 (52.8 - 62.8%) -- 99.6% chance to 2HKO after Leftovers recovery

Gardevoir @ Gardevoirite
Ability: Trace
EVs: 24 Def / 232 SpA / 252 Spe
Timid Nature
- Hyper Voice
- Psyshock
- Focus Blast
- Will-O-Wisp

Standard Wallbreaker Mega Gardevoir annihilates this core, only fearing a 2HKO from an unburned Hippowdon if she is the one switching in. Status obviously troubles her as it does many offensive mons, but as long as she is above 30% (+ whatever damage hazards inflict), Gardevoir can switch into and OHKO Latias and Infernape (needs rocks for the former) and 2HKO Hippowdon. Forcing switches makes Gardvoir a good partner to hazard stackers, which especially eat into Hippowdon and Infernape due to Spikes and make them easy to overload for what they're intended to check, if not simply softening them up for Gardevoir herself.

232 SpA Pixilate Mega Gardevoir Hyper Voice vs. 248 HP / 0 SpD Mega Latias: 320-378 (88.1 - 104.1%) -- 25% chance to OHKO
232 SpA Pixilate Mega Gardevoir Hyper Voice vs. 252 HP / 112 SpD Hippowdon: 256-303 (60.9 - 72.1%) -- guaranteed 2HKO after Leftovers recovery

0 SpA Mega Latias Ice Beam vs. 0 HP / 0 SpD Mega Gardevoir: 68-80 (24.5 - 28.8%) -- 99.5% chance to 4HKO
0 SpA Mega Latias Thunderbolt vs. 0 HP / 0 SpD Gardevoir: 77-91 (27.7 - 32.8%) -- guaranteed 4HKO

0 Atk Hippowdon Earthquake vs. 0 HP / 24 Def Mega Gardevoir: 162-192 (58.4 - 69.3%) -- guaranteed 2HKO after sandstorm damage
0 Atk burned Hippowdon Earthquake vs. 0 HP / 24 Def Mega Gardevoir: 81-96 (29.2 - 34.6%) -- guaranteed 3HKO after sandstorm damage

Reserving Crawdaunt

+2 252 Atk Life Orb Adaptability Crawdaunt Aqua Jet vs. 248 HP / 68 Def Mega Latias: 87-103 (23.9 - 28.3%) -- 93.4% chance to 4HKO
0 SpA Mega Latias Thunderbolt vs. 4 HP / 0 SpD Crawdaunt: 280-330 (104.4 - 123.1%) -- guaranteed OHKO

uhhh... how do you expect Crawdaunt to threaten M-Latias (it also gets burned by Infernape which survives an unboosted Aqua Jet)? I mean, M-Latias isn't going to hard-switch into Crawdaunt for sure.

Anyway, I'm gonna take Feraligatr.

Feraligatr @ Life Orb
Ability: Sheer Force
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Dragon Dance
- Waterfall
- Crunch
- Superpower / Ice Punch

Feraligatr easily sets up in front of Hippowdon (unless it carries Whirlwind, which isn't the case here) before OHKOing the whole core with the appropriate move. However, it doesn't like hard-switching into any members of the core (except Hippowdon's SR or Slack Off), so the best strategy here would be to find the opportunity to safely switch it into Hippo (after one of your mon has died/been sacked, with a slow VoltTurn or on a predicted switch) before sweeping.

Calcs

+1 252 Atk Life Orb Sheer Force Feraligatr Crunch vs. 248 HP / 68 Def Mega Latias: 309-364 (85.1 - 100.2%) -- 6.3% chance to OHKO (81.3% chance to OHKO after SR)
252 Atk Life Orb Sheer Force Feraligatr Waterfall vs. 248 HP / 88 Def Infernape: 447-530 (125.9 - 149.2%) -- guaranteed OHKO (get a DD boost before taking on Infernape to not get burned)
+1 252 Atk Life Orb Sheer Force Feraligatr Waterfall vs. 252 HP / 144+ Def Hippowdon: 398-471 (94.7 - 112.1%) -- 68.8% chance to OHKO (guaranteed OHKO after SR)

Clefable @ Leftovers
Ability: Magic Guard
EVs: 252 HP / 172 Def / 84 SpD
Calm Nature
- Calm Mind
- Moonblast
- Soft-Boiled
- Thunder Wave

Clefable uses Mega Latias and Hippowdon as set-up bait while being able to defeat Infernape 1 v 1 with Moonblast. Encore variants are more troublesome but it can't switch into Clefable anyway.

Gyarados @ Gyaradosite
Ability: Intimidate
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
- Dragon Dance
- Crunch
- Waterfall
- Substitute

Mega Gyarados is annoyed somewhat by the status spreading theme that the core has going on, so running a subdd set is a pretty cool way of getting around that (although it has to sub vs hippo). If it can successfully get to +1, then it outspeeds and ohkos every single member of the core with its STAB moves without having to worry about annoying shit like twave and wisp bar hippo, who can only eq back. Also, it can eat tbolt from lati, eq from hippo, and low kick from infernape, and then it gets to +1 and destroys their lives quite easily.

Calcs

+1 252+ Atk Mold Breaker Mega Gyarados Waterfall vs. 248 HP / 88 Def Infernape: 578-684 (162.8 - 192.6%) -- guaranteed OHKO
0 Atk Infernape Low Kick (120 BP) vs. 0 HP / 4 Def Mega Gyarados: 248-294 (74.9 - 88.8%) -- guaranteed 2HKO

Garchomp @ Yache Berry
Ability: Rough Skin
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Outrage
- Earthquake
- Stone Edge / Rock Slide
- Swords Dance

Yache Berry Garchomp actually lures Latias as Ice Beam is an apparent OHKO, but with the Berry in tandem with Outrage it OHKOes it after Stealth Rock Damage. Infernape is easily outran and KO'ed by Earthquake before it can burn it and Hippowdon does not carry Whirlwind making it setup fodder.

Aerodactyl-Mega @ Aerodactylite
Ability: Tough Claws
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Aerial Ace
- Stone Edge
- Ice Fang
- Pursuit

Chip off Dugtrio then kill M-Pidgeot. I'm pretty sure Memento isn't enough to stop M-Aero from killing off the bird and Stone Edge from Dugtrio is too weak to take care of Aero without prior damage.

Edit: are we still using Hyper Beam on Pidgeot seriously?!?!? AAAAAAAAHHHRRGGR

Weavile @ Life Orb
Ability: Pressure
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Knock Off
- Icicle Crash
- Ice Shard
- Poison Jab / Low Kick

Weavile is able to easily outspeed Dugtrio and Pidgeot and OHKO both of them with Icicle Crash. Dugtrio's Focus Sash generally has to be broken before Weavile can take out both members, though, but that's not a difficult task with something like Stealth Rock. Ice Shard OHKOs Dugtrio if you don't want to take Sucker Punch damage. Weavile can't switch in to anything the two want to do though.

252 Atk Life Orb Weavile Knock Off vs. 0 HP / 0- Def Dugtrio: 328-386 (163.1 - 192%) -- guaranteed OHKO

Rotom-W @ Leftovers
Ability: Levitate
EVs: 248 HP / 252 Def / 8 SpD
Bold Nature
IVs: 0 Atk
- Volt Switch
- Hydro Pump
- Thunder Wave
- Pain Split

T-Wave Rotom-W fucks over this core pretty badly as Dugtrio can't touch it (not even trap it due to Levitate) and both of M-Pidgeot's main attacking moves are resisted by it. In return, Rotom-W OHKOes Dugtrio with Hydro Pump if its sash is broken and paralyses M-Pidgeot before 2HKOing it with Volt Switch (or you could just use Volt Switch to safely place one of its teammates on the field). Hyper Beam does a lot though, so I guess the SpDef variant could threaten this core even better, but it isn't commonly run on M-Pidgeot nowadays, so I'll leave it that way.

Calcs

252 SpA Mega Pidgeot Hurricane vs. 248 HP / 8 SpD Rotom-W: 87-102 (28.7 - 33.6%) -- 98.8% chance to 4HKO after Leftovers recovery
252 Atk Dugtrio Stone Edge vs. 248 HP / 252+ Def Rotom-W: 55-65 (18.1 - 21.4%) -- possible 7HKO after Leftovers recovery
252 Atk Dugtrio Reversal (200 BP) vs. 248 HP / 252+ Def Rotom-W: 108-128 (35.6 - 42.2%) -- 92.8% chance to 3HKO after Leftovers recovery

Kyurem-Black @ Choice Scarf
Ability: Teravolt
EVs: 252 Atk / 32 SpA / 224 Spe
Naive Nature
- Ice Beam
- Outrage
- Fusion Bolt
- Dragon Claw

Kyurem Black decimates this core by basically clicking any move that isn't fusion bolt, when stealth rock is in play, which allows for OHKOs (or 50% chance to OHKO with Dragon Claw VS Mega-Pidgeot). Even without rocks, unless Dugtrio runs Sucker Punch+Reversal already has Stealth Rock on the field and is still somehow at 100% health, it cannot beat Kyurem-Black and Pidgeot still loses unless it crits after Kyurem-Black gets Memento'd.

SD Gliscor

Gliscor @ Toxic Orb
Ability: Poison Heal
EVs: 244 HP / 8 Def / 200 SpD / 56 Spe
Careful Nature
- Swords Dance
- Earthquake
- Stone Edge
- Roost

SD Gliscor uses Dugtrio as a set-up fodder because tanks everything thrown at it including a Memento (which is balanced by a Swords Dance).
252 Atk Dugtrio Stone Edge vs. 244 HP / 8 Def Gliscor: 65-77 (18.4 - 21.8%) -- possibly the worst move ever
This is the best Dugtrio can do.

Mega Pidgeot is a little harder to wear down but, thanks to Poison Heal and the double-edged No Guard, Stone Edge won't fail to hit the target. Just be sure to be at full health to tank Hurricane at your best.

0 Atk Gliscor Stone Edge vs. 0 HP / 4 Def Mega Pidgeot: 166-196 (54 - 63.8%) -- guaranteed 2HKO

guaranteed OHKO at +2 (Swords Dance is the key to dismantle this core)​

252 SpA Mega Pidgeot Hurricane vs. 244 HP / 200+ SpD Gliscor: 169-199 (48 - 56.5%) -- 0.4% chance to 2HKO after Poison Heal (the confusion chance is more likely to happen)

252 SpA Mega Pidgeot Hyper Beam vs. 244 HP / 200+ SpD Gliscor: 229-271 (65 - 76.9%) -- guaranteed 2HKO after Poison Heal
Hyper Beam (seriously?) solidly 2HKOes in the but Gliscor wins in every scenario if it is at high health after a Swords Dance or if is able to do 2 Stone Edge in a row (remember that Hyper Beam gives us a free turn).

Chansey laughs at anything the core can throw at it and can whittle down the core with repeated Seismic Toss. If Mega Pidgeot tries to Roost Stall, it gets Toxiced to death instead while Chansey heals off any damage with Soft-Boiled.

Heatran @ Choice Scarf
Ability: Flash Fire
EVs: 28 HP / 252 SpA / 228 Spe
Timid Nature
- Fire Blast
- Flash Cannon
- Earth Power
- Stone Edge
A set very uncommon now on days but against this core works perfectly combined with hazards just to break Dugtrio sash, and also secure the HKO on Pidgeot. Heatran is able to switch into Pidgeot however make sure you have hazard so Dugtrio can't trap you and retaliate back, also No Guard help us as we cannot miss the Fire Blast.
252 SpA Heatran Fire Blast vs. 0 HP / 0 SpD Dugtrio: 292-345 (145.2 - 171.6%) -- guaranteed OHKO
252 SpA Heatran Fire Blast vs. 0 HP / 0 SpD Mega Pidgeot: 217-256 (70.6 - 83.3%) -- 62.5% chance to OHKO after Stealth Rock
