Project Victim of the Week

[SketchUp]

Since Work Up MPidgeot is mainly used as a stallbreaker, I chose one of the few pokemon on stall that can beat MPidgeot and that isn't as gimmicky as MAmphy, Rhyperior etc.

Counter

Heatran @ Leftovers
Ability: Flash Fire
EVs: 248 HP / 192 SpD / 68 Spe
Calm Nature
- Lava Plume
- Toxic
- Taunt / Roar
- Protect / Stealth Rock

Heatran takes little damage from Hurricane and can beat even a boosted MPidgeot easily. Lava Plume does over 40%, so MPidgeot won't be able to break through Heatran, because there is a chance to burn (even without burns, MPidgeot is forced to roost at least 4 out of 5 turns) An other way Heatran can beat MPidgeot is with the combination of Taunt and Toxic / Protect / Roar. Even weakened Heatran can put pressure on MPidgeot with Toxic and use the turns to get leftovers recovery back.

0 SpA Heatran Lava Plume vs. 0 HP / 0 SpD Mega Pidgeot: 130-154 (42.3 - 50.1%) -- 0.4% chance to 2HKO

 

[AM]

I know this isn't, really a thing, but I think a lot of these "counters" need to contend with the pretty significant confusion rate that comes from Hurricane. For example, Heatran up above me is super shaky if not even remotely reliable in practice, reason being I've seen and beat a lot of those variants just off of a combination of confusion rate and boosting. The Scarf rachi and the Ttar one up above me is more effective to call "counter" because Ttars increased bulk in sand and move options that celebitrainer36 provided allows it to take it on 1v1 and Scarf Rachi from Dr Ciel outspeeds as such will pressure M-Pidgeot enough on the teams both M-Pidgeot and Scarf Rachi are associated with.

If you're gonna call something a counter, call it on the term of practicality not just the lame definition of "it switches into it and can't do nothing back therefore it's a counter." That's easier said than done for a lot of past "counters" I've seen.

Magnezone as a Counter

Magnezone @ Choice Specs
Ability: Magnet Pull
EVs: 172 HP/ 252 SpA/ 84 Spe
Modest Nature
-Thunderbolt
-Volt Switch
-Hidden Power Fire
-Flash Cannon

Standard Specs Mag is something that offensive teams can use as a safe switch-in to Mega Pidgeot. It takes very little damage from an unboosted Hurricane and isn't fazed by boosted ones unless Mega Pidgeot is already at +4. Magnezone rips Mega Pidgeot apart with Specs Thunderbolt, and even after Roosting Pidgeot still has a high chance to be OHKO'd. The only way Mega Pidgeot can hope to beat Mag 1v1 is to get extremely lucky with confusion.

Calcs:

252+ SpA Choice Specs Magnezone Thunderbolt vs. 4 HP / 0 SpD Mega Pidgeot: 582-686 (188.9 - 222.7%) -- guaranteed OHKO (If Pidgeot doesn't Roost)

252+ SpA Choice Specs Magnezone Thunderbolt vs. 4 HP / 0 SpD Mega Pidgeot: 291-343 (94.4 - 111.3%) -- 68.8% chance to OHKO (If Pidgeot does Roost- Flying type removed in calc)

252+ SpA Mega Pidgeot Hurricane vs. 172 HP / 0 SpD Magnezone: 55-65 (16.9 - 20%) -- possible 5HKO (Zero shits given)

+3 252+ SpA Mega Pidgeot Hurricane vs. 172 HP / 0 SpD Magnezone: 138-162 (42.5 - 50%) -- 0.4% chance to 2HKO (Very unlikely to 2HKO, but confusion is feared)

 

[Albacore]

Aerodactyl @ Aerodactylite
Ability: Pressure
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Stone Edge
- Aerial Ace
- Ice Fang / Fire Fang / Aqua Tail
- Roost

Easily switches into a Hurricane, and can Roost the damage off. OHKOs back with Stone Edge, or 2HKOs back with Aerial Ace.

252 SpA Mega Pidgeot Hurricane vs. 0 HP / 0 SpD Mega Aerodactyl: 96-114 (31.8 - 37.8%) -- 92.7% chance to 3HKO

252 Atk Mega Aerodactyl Stone Edge vs. 4 HP / 0 Def Mega Pidgeot: 408-480 (132.4 - 155.8%) -- guaranteed OHKO

252 Atk Tough Claws Mega Aerodactyl Aerial Ace vs. 4 HP / 0 Def Mega Pidgeot: 162-192 (52.5 - 62.3%) -- guaranteed 2HKO

 

[Sanger Zonvolt]

Name: Scarf Kyurem-B
Status: Check

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

With a Choice Scarf, Kyurem-B can outspeed Mega Pidgeot and OHKO using Fusion Bolt:
252 Atk Teravolt Kyurem-B Fusion Bolt vs. 4 HP / 0 Def Mega Pidgeot: 322-380 (104.5 - 123.3%) -- guaranteed OHKO

While it can stomach a Hurricane, if you become confused, you will likely have to switch out since it can't stomach two consecutive Hurricanes:
252 SpA Mega Pidgeot Hurricane vs. 0 HP / 0- SpD Kyurem-B: 225-265 (57.5 - 67.7%) -- guaranteed 2HKO after Stealth Rock

Weavile as a Check

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

Pretty simple. Weavile can't switch into Hurricane after SR (well, it's just better to not directly switch it into any damaging move due to its frailty and LO recoil), but when it faces M-Pidgeot, Weavile outspeeds and easily OHKOes it with Icicle Crash (or even Ice Shard if M-Pidgeot is at 63% or less). Just prey to the Hax Gods that you actually don't miss it! Forgot it can't miss due to M-Pidgeot's No Guard. Thank you escarlata for catching that!

Calcs

252 SpA Mega Pidgeot Hurricane vs. 0 HP / 0 SpD Weavile: 211-250 (75 - 88.9%) -- guaranteed OHKO after Stealth Rock (don't switch into that!)

252 Atk Life Orb Weavile Icicle Crash vs. 0 HP / 4 Def Mega Pidgeot: 408-484 (132.8 - 157.6%) -- guaranteed OHKO

 

[michaeloche]

Diancie @ Diancite
Ability: Clear Body
EVs: 32 Atk / 224 SpA / 252 Spe
Naive Nature
- Moonblast
- Diamond Storm
- Earth Power
- Protect / Hidden Power [Fire] / Psychic

Role: Counter

Mega Diancie is not 2HKOed by unboosted Hurricane, and Diamond Storm is a clean OHKO back.

Calcs

252 SpA Mega Pidgeot Hurricane vs. 0 HP / 0- SpD Mega Diancie: 95-112 (39.4 - 46.4%) -- guaranteed 3HKO

252 SpA Mega Pidgeot Hurricane vs. 0 HP / 0- SpD Diancie: 72-85 (29.8 - 35.2%) -- 23.1% chance to 3HKO (this is non-mega Diancie, by the way)

32 Atk Mega Diancie Diamond Storm vs. 0 HP / 4 Def Mega Pidgeot: 398-470 (129.6 - 153%) -- guaranteed OHKO

AV Raikou as a Counter

Raikou @ Assault Vest
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Thunderbolt
- Volt Switch
- Hidden Power Ice
- Shadow Ball

Thanks to Assault Vest, Raikou can easily survive two Hurricanes or a +1 Hurricane and KO Pidgeot with Thunderbolt, or have a good chance to OHKO with Volt Switch.

Calcs:

Pidgeot vs. Raikou
252 SpA Pidgeot Hurricane vs. 0 HP / 4 SpD Assault Vest Raikou: 40-48 (12.4 - 14.9%) -- possible 7HKO
+1 252 SpA Pidgeot Hurricane vs. 0 HP / 4 SpD Assault Vest Raikou: 60-71 (18.6 - 22.1%) -- possible 5HKO

Raikou vs. Pidegot
252 SpA Raikou Thunderbolt vs. 0 HP / 0 SpD Pidgeot: 362-428 (117.9 - 139.4%) -- guaranteed OHKO
252 SpA Raikou Volt Switch vs. 0 HP / 0 SpD Pidgeot: 282-332 (91.8 - 108.1%) -- 50% chance to OHKO

Mega Ampharos as Counter

Fabio (Ampharos-Mega) @ Ampharosite
Ability: Mold Breaker
EVs: 248 HP / 248 Def / 12 Spe
Bold Nature
- Rest
- Sleep Talk
- Volt Switch
- Dragon Pulse

Mega Ampharos Electric typing and bulk makes Mega Pidgeot's Hurricane not even 2HKO, not even at +1. Mega Amph and also hit back with a Volt Switch, but Mega Pidgeon will probably switch out anyway.

252 SpA Mega Pidgeot Hurricane vs. 248 HP / 0 SpD Ampharos: 101-119 (26.3 - 31%) -- guaranteed 4HKO
+1 252 SpA Mega Pidgeot Hurricane vs. 248 HP / 0 SpD Ampharos: 151-178 (39.4 - 46.4%) -- guaranteed 3HKO

 

[Random Passerby]

Name : Manectric
Status: Check

Manectric @ Manectite
Ability: Lightningrod
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Thunderbolt
- Volt Switch
- Overheat
- Hidden Power Ice

Mega Manectric can switch into any of the move Mega Pidgeot carries and then outspeed and OHKO it back as long as it avoids confusion. However, taking 2 successive Hurricanes while Rocks are up will knock Manectric out.

Calculations

252 SpA Mega Pidgeot Hurricane vs. 0 HP / 0 SpD Mega Manectric: 111-131 (39.5 - 46.6%) -- 32.4% chance to 2HKO after Stealth Rock
252 SpA Mega Manectric Thunderbolt vs. 0 HP / 0 SpD Mega Pidgeot: 366-432 (119.2 - 140.7%) -- guaranteed OHKO
252 SpA Mega Manectric Volt Switch vs. 0 HP / 0 SpD Mega Pidgeot: 284-336 (92.5 - 109.4%) -- 56.3% chance to OHKO

Weavile as a Check

Weavile @ Life Orb
Ability: Pressure
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Knock Off

- Low Kick

Pretty simple. Weavile can't switch into Hurricane after SR (well, it's just better to not directly switch it into any damaging move due to its frailty and LO recoil), but when it faces M-Pidgeot, Weavile outspeeds and easily OHKOes it with Icicle Crash (or even Ice Shard if M-Pidgeot is at 63% or less).

Thundurus-I as a Soft Counter

Thundurus @ Life Orb
Ability: Prankster
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Thunder Wave
- Thunderbolt
- Hidden Power Ice
- Focus Blast

I'm listing this as a soft counter because, while Thundy can OHKO Mega Pidgeot with Thunderbolt, a +1 Pidgeot that uses Hurricane on Thundurus could get the 2HKO, as well as being able to outspeed Thundurus, so unless you sacrifice one of your mons or use a slower Volt Switcher/U-Turner, Thundurus can't safely switch against a +1 Pidgeot. However, if you switch in while it's setting up, then you can OHKO Mega Pidgeot with Thunderbolt. If Pidgeot chooses to use Hurricane right away without using Work Up, however, then it won't be 2HKO'd.

Calcs:

252 SpA Life Orb Thundurus Thunderbolt vs. 0 HP / 0 SpD Mega Pidgeot: 447-530 (145.6 - 172.6%) -- guaranteed OHKO

252 SpA Mega Pidgeot Hurricane vs. 0 HP / 0 SpD Thundurus: 111-131 (37.1 - 43.8%) -- guaranteed 3HKO

+1 252 SpA Mega Pidgeot Hurricane vs. 0 HP / 0 SpD Thundurus: 166-196 (55.5 - 65.5%) -- guaranteed 2HKO

Empoleon as a Counter

Empoleon @ Leftovers
Ability: Torrent
EVs: 248 HP / 8 Def / 252 SpD
Calm Nature
- Scald
- Ice Beam
- Stealth Rock
- Toxic/Defog

This week I'm nominating the rarely seen Empoleon as my Pidgeot-Mega counter of choice. Pidgeot-M has a very limited good offensive typing attack pool that can work with it, so finding a good wall wasn't hard at all. You'll mostly come across hurricane, heatwave, and u-turn 9/10 times. So what I've done is just simply get a specially defensive wall that eats up it's STAB hurricane and heat wave. Nothing really more to say.

Calcs:

vs.

252 SpA Mega Pidgeot Hurricane vs. 248 HP / 252+ SpD Empoleon: 66-78 (17.7 - 21%) -- possible 7HKO after Leftovers recovery
252 SpA Mega Pidgeot Heat Wave vs. 248 HP / 252+ SpD Empoleon: 76-90 (20.4 - 24.2%) -- possible 6HKO after Leftovers recovery

vs.

0 SpA Empoleon Ice Beam vs. 4 HP / 0 SpD Mega Pidgeot: 170-202 (55.1 - 65.5%) -- guaranteed 2HKO

Ability: Clear Body
EVs: 32 Atk / 224 SpA / 252 Spe
Naive Nature
- Moonblast
- Diamond Storm
- Earth Power
- Protect / Hidden Power [Fire] / Psychic

Role: Counter

Mega Diancie is not 2HKOed by unboosted Hurricane, and Diamond Storm is a clean OHKO back.

Calcs

252 SpA Mega Pidgeot Hurricane vs. 0 HP / 0- SpD Mega Diancie: 95-112 (39.4 - 46.4%) -- guaranteed 3HKO

252 SpA Mega Pidgeot Hurricane vs. 0 HP / 0- SpD Diancie: 72-85 (29.8 - 35.2%) -- 23.1% chance to 3HKO (this is non-mega Diancie, by the way)

32 Atk Mega Diancie Diamond Storm vs. 0 HP / 4 Def Mega Pidgeot: 398-470 (129.6 - 153%) -- guaranteed OHKO

it's a minor nitpick, but I'd list this as a soft counter, mainly because of what AM said:

I know this isn't, really a thing, but I think a lot of these "counters" need to contend with the pretty significant confusion rate that comes from Hurricane. For example, Heatran up above me is super shaky if not even remotely reliable in practice, reason being I've seen and beat a lot of those variants just off of a combination of confusion rate and boosting. The Scarf rachi and the Ttar one up above me is more effective to call "counter" because Ttars increased bulk in sand and move options that celebitrainer36 provided allows it to take it on 1v1 and Scarf Rachi from Dr Ciel outspeeds as such will pressure M-Pidgeot enough on the teams both M-Pidgeot and Scarf Rachi are associated with.

If you're gonna call something a counter, call it on the term of practicality not just the lame definition of "it switches into it and can't do nothing back therefore it's a counter." That's easier said than done for a lot of past "counters" I've seen.

For Example:

1) Mega Diancie switches in on a Hurricane, but gets confused.
2) Mega Diancie hits itself in confusion, whilst Pidgeot fires off another Hurricane.
3) Pidgeot fires off another Hurricane (being faster) and KOs.

Again, this isn't always going to happen, but given what AM said about the significant confusion chance I think it should be taken into consideration

 

[Vinc608]

Diancie-Mega is a hard check and not a counter : not because it could hits itself in confusion (Heatran 3HKOs iirc while Diancie OHKO), but because it can't switch in twice.

 

[SketchUp]

Mega Pidgeot still has the upperhand anyway even without the confusion rate because with a Naive nature Hurricane can 2hko after Stealth Rock and Mega Diancie can't recover off any damage so after switching in against one Hurricane it will lose again if it switches in on Hurricane / Work Up / when Stealth Rock are up in the first place. IMO the confusion chance isn't that big of a deal in the first place especially if you take only 20-25% from Hurricane

 

[AM]

I think the terms check and counter is kind of dumb in practice but people let it slide for the sake of learning. "Hard" checks and "hard" counters are think are not necessary ever as terms.

 

[MANNAT]

Metagross as a hard check (confusion sucks)

Metagross @ Metagrossite
Ability: Clear Body
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Meteor Mash
- Zen Headbutt
- Bullet Punch
- Ice Punch

Hurricane is a paltry 4hko on mega metagross, so it is pretty safe to switch in this set and it can knock out pidgeot with a combination of any of its moves+bp (or a 50% chance to ohko with ice punch). It's a pretty self explanatory check, but if it is below 70ish%, then watch out for confusion because hax may lead Metagross to lose the matchup. Below are some calcs and a replay to demonstrate my point further.

Counter

Rhyperior @ Leftovers
Ability: Solid Rock
EVs: 212 HP / 44 Atk / 252 Def

- Ice Punch

252 SpA Mega Pidgeot Hurricane vs. 212 HP / 0 SpD Rhyperior: 149-176 (35.1 - 41.5%) -- 99.9% chance to 3HKO after Stealth Rock and Leftovers recovery
44+ Atk Rhyperior Stone Edge vs. 0 HP / 4 Def Mega Pidgeot: 392-464 (127.6 - 151.1%) -- guaranteed OHKO

Aggron @ Aggronite
Ability: Sturdy

Impish Nature
- Stealth Rock

252 SpA Mega Pidgeot Hurricane vs. 252 HP / 240 SpD Mega Aggron: 85-101 (24.7 - 29.3%) -- 100% chance to 4HKO

Self explanatory. Aggron is only 4HKOed, by Pidgeot. Heavy Slam returns a guarantees 2HKO whereas Avalanche has a decent chance to OHKO. Confusion sucks though, and I know that because I haxed past god knows how many mons with my Pidgeot that way

 

[GnralLao]

Scarfed nominations coming up!

So, Magnezone was nominated, but not Magneton? Shame.


Magneton as a Hard Check / Soft Counter

Magneton @ Choice Scarf
Ability: Magnet Pull
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
IVs: 0 Atk / 30 SpA / 30 Spe
- Volt Switch
- Hidden Power Fire
- Flash Cannon
- Thunderbolt

Works just the same as Magnezone, but I think it works even better at checking M-Pidgeot. Why? Well, unlike Magnezone, Magneton is faster than M-Pidgeot and because of that, the chances of being confused by Hurricanes remain at 30% only whereas Magnezone's chances are at 51% since if it switches into a Hurricane, it can be hit another one. Also, even with Magnezone's superior bulk, one Hurricane on Magneton still does less damage than two Hurricanes on Magnezone. On top of that, even with Magneton lesser firepower, it still does a fine job at OHKOing M-Pidgeot with Thunderbolt or Volt Switch after SR.

Calcs

252 SpA Mega Pidgeot Hurricane vs. 0 HP / 0 SpD Magneton: 61-73 (25.3 - 30.2%) -- guaranteed 4HKO

252 SpA Magneton Volt Switch vs. 0 HP / 0 SpD Mega Pidgeot: 260-308 (84.6 - 100.3%) -- guaranteed OHKO after Stealth Rock
252 SpA Magneton Thunderbolt vs. 0 HP / 0 SpD Mega Pidgeot: 336-396 (109.4 - 128.9%) -- guaranteed OHKO

Terrakion as a Check

Terrakion @ Choice Scarf
Ability: Justified
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Close Combat
- Stone Edge
- Rock Slide
- Iron Head

Terrakion can switch into M-Pidgeot's status moves, but hates taking a Hurricane to the face as it'll 2HKO it, which means if Terrakion gets confused on the switch-in and gets hurt in its confusion on the next turn, it becomes bird food. Otherwise, Terrakion outspeeds and OHKOes M-Pidgeot with a perfectly accurate Stone Edge.

Calcs

252 SpA Mega Pidgeot Hurricane vs. 0 HP / 4 SpD Terrakion: 202-238 (62.5 - 73.6%) -- guaranteed 2HKO

252 Atk Terrakion Stone Edge vs. 0 HP / 4 Def Mega Pidgeot: 390-462 (127 - 150.4%) -- guaranteed OHKO

Victini as a Check

Victini @ Choice Scarf
Ability: Victory Star
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- V-create
- Bolt Strike
- U-turn
- Final Gambit

Uses Final Gambit and kills M-Pidgeot. The end. In all seriousness, this is pretty much the same as above. It can switch into anything but Hurricane due to being 2HKOed by it and in return, Victini outspeeds and OHKOes M-Pidgeot with V-create or Bolt Strike.

Calcs

252 SpA Mega Pidgeot Hurricane vs. 0 HP / 0 SpD Victini: 186-219 (54.5 - 64.2%) -- guaranteed 2HKO

252+ Atk Victini Bolt Strike vs. 0 HP / 4 Def Mega Pidgeot: 310-366 (100.9 - 119.2%) -- guaranteed OHKO
252+ Atk Victini V-create vs. 0 HP / 4 Def Mega Pidgeot: 322-379 (104.8 - 123.4%) -- guaranteed OHKO

Week 76: Substitute SD Garchomp

Ability: Serene Grace
EVs: 252 HP / 76 Def / 4 SpD / 176 Spe
Timid Nature
- Nasty Plot
- Air Slash
- Thunder Wave / Heal Bell / Fire Blast
- Roost

Togekiss is probably the hardest counter to Garchomp, being immune to both of Garchomp's STABs. It can really do anything it wants once it's inside, including setting up with the above set.

Quagsire as a Counter

Quagsire @ Leftovers
Ability: Unaware
EVs: 252 HP / 252 Def / 4 SpD
Relaxed Nature
- Scald
- Earthquake
- Recover
- Toxic

Do to its typing, abilty and physical bulk, Quagise is easily able to counter SubSD Garchomp. It can't 2HKO Quagsire after SR and 2 layers of Spikes while the latter's Scald can inflict burns to it and its Earthquake breaks Chomp's Sub 100% of the time. Quagsire also has access to reliable recovery in the form of Recover to heal off the damage done by Chomp. On top of that, like the SD boost(s), the Salac boost is ignored by Quagsire due to Unaware (it doesn't really matter since Quagsire is already so darn slow, but I guess it's something...). Nvm that, Unaware actually doesn't negate Speed boosts... weird. Thank you KidMagic for catching that!

Calcs

244 Atk Garchomp Earthquake vs. 252 HP / 252+ Def Unaware Quagsire: 130-154 (32.9 - 39%) -- guaranteed 3HKO after Stealth Rock, 2 layers of Spikes, and Leftovers recovery

0 SpA Quagsire Scald vs. 12 HP / 0 SpD Garchomp: 70-84 (19.4 - 23.3%) -- possible 5HKO
0 Atk Quagsire Earthquake vs. 12 HP / 0 Def Garchomp: 99-117 (27.5 - 32.5%) -- guaranteed 4HKO
