Project Victim of the Week

[Random Passerby]

Name: Chansey
Status: Counter

Chansey @ Eviolite
Ability: Natural Cure
EVs: 4 HP / 252 Def / 252 SpD
Bold Nature
- Toxic / Thunder Wave
- Soft-Boiled
- Seismic Toss
- Heal Bell

Chansey barely takes any damage from any of Mega Ampharos's attacks and can heal up with Soft-Boiled. Chansey can also wear Mega Ampharos down with Seismic Toss or land a Toxic on it.

Calculations

252+ SpA Mold Breaker Mega Ampharos Focus Blast vs. 4 HP / 252 SpD Eviolite Chansey: 176-208 (27.4 - 32.3%) -- 76.6% chance to 3HKO after Stealth Rock
252+ SpA Mold Breaker Mega Ampharos Thunderbolt vs. 4 HP / 252 SpD Eviolite Chansey: 99-117 (15.4 - 18.2%) -- possible 6HKO
Chansey Seismic Toss vs. 4 HP Mega Ampharos: 100-100 (31 - 31%) -- guaranteed 3HKO after Stealth Rock

Mega Swampert as a check

Swampert-Mega @ Swampertite
Ability: Swift Swim
EVs: 252 HP / 4 Def / 252 SpD
Careful Nature
- Waterfall
- Earthquake
- Curse
- Rest

Mega Swampert can avoid the 2HKO from any of Mega Ampharos's attacks and can OHKO back with a Super Effective Earthquake. Rest is used to heal up and check threats longer.

Calculations

252+ SpA Mold Breaker Mega Ampharos Dragon Pulse vs. 252 HP / 252+ SpD Mega Swampert: 124-147 (30.6 - 36.3%) -- 99.4% chance to 3HKO after Stealth Rock
252+ SpA Mold Breaker Mega Ampharos Focus Blast vs. 252 HP / 252+ SpD Mega Swampert: 116-137 (28.7 - 33.9%) -- 50.7% chance to 3HKO after Stealth Rock
0 Atk Mega Swampert Earthquake vs. 4 HP / 0 Def Mega Ampharos: 294-348 (91.3 - 108%) -- guaranteed OHKO after Stealth Rock

Tangrowth @ Assault Vest
Ability: Regenerator
EVs: 252 HP / 4 Def / 252 SpD
Sassy Nature
- Leaf Storm
- Knock Off
- Earthquake
- Hidden Power Ice

Takes any hit from Mega Ampharos.
0 Atk Tangrowth Earthquake vs. 4 HP / 0 Def Mega Ampharos: 138-164 (42.8 - 50.9%) -- 3.9% chance to 2HKO
252+ SpA Mold Breaker Mega Ampharos Dragon Pulse vs. 252 HP / 252+ SpD Assault Vest Tangrowth: 132-156 (32.6 - 38.6%) -- 98.6% chance to 3HKO

Doesn't do much back, but takes nothing

I had already gotten Mega Altaria typed out then I noticed a reservation that appeared...ah well.

Tangrowth isn't really a counter, you can switch in against 2 D-Pulses, but since you have no reliable recovery and can't OHKO back, you are more so of a check.

Clefable as a Counter

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

Everyone's favorite pink blob not named Chansey or Blissey is able to avoid a 2HKO after rocks. Upon switch-in it is free to recover if needed or fire off a moonblast to 2HKO.

Calcs:

252+ SpA Mold Breaker Mega Ampharos Thunderbolt vs. 252 HP / 96+ SpD Clefable: 172-204 (43.6 - 51.7%) -- guaranteed 3HKO after Leftovers recovery

0 SpA Clefable Moonblast vs. 4 HP / 0 SpD Mega Ampharos: 182-216 (56.5 - 67%) -- guaranteed 2HKO

PP may be an issue, but I believe clef is capable of stalling it out just fine, even in a worst-case scenario.

 

[DarkNostalgia]

Conkeldurr @ Assault Vest
Ability: Guts
EVs: 252 Atk / 236 SpD / 20 Spe
Adamant Nature
- Drain Punch
- Mach Punch
- Ice Punch
- Poison Jab / Knock Off

Assault Vest Conkeldurr avoids the 2HKO from any move, even Thunderbolt, and 2HKOes back with Ice Punch. Is not a counter because it lacks recovery and if it switches into Mega Ampharos manually it loses to three Thunderbolts.

252+ SpA Mold Breaker Mega Ampharos Thunderbolt vs. 0 HP / 236 SpD Assault Vest Conkeldurr: 135-160 (38.4 - 45.5%) -- guaranteed 3HKO
252+ Atk Conkeldurr Ice Punch vs. 4 HP / 0 Def Mega Ampharos: 182-216 (56.5 - 67%) -- guaranteed 2HKO

- Moonlight
- Toxic/Thunder Wave
252+ SpA Mold Breaker Mega Ampharos Thunderbolt vs. 252 HP / 112 SpD Cresselia: 141-166 (31.7 - 37.3%) -- 0% chance to 3HKO after Leftovers recovery
0 SpA Cresselia Ice Beam vs. 4 HP / 0 SpD Mega Ampharos: 94-112 (29.1 - 34.7%) -- 8% chance to 3HKO
0 SpA Cresselia Psychic vs. 4 HP / 0 SpD Mega Ampharos: 70-84 (21.7 - 26%) -- 3.6% chance to 4HKO
252+ SpA Mold Breaker Mega Ampharos Thunderbolt vs. 252 HP / 112 SpD Cresselia: 141-166 (31.7 - 37.3%) -- 0% chance to 3HKO after Leftovers recovery
So Cress Handles Ampharos Pretty well, skill swap is for other stuff. Ice beam is a solid attacking option to hit Ampharos as well as other popular ground types that it also switchs in on. skill swap is unrelated to this weeks choice, but it is for -Ate abilities as well as Azu/Diggersby. Twave and Toxic are fine options that are interchangable, but this Cress is designed to beat mega ampharos so I'd suggest using toxic. Moonlight is the best reliable recovery cresselia gets. I run 4 speed evs on Cress because im always paranoid people are going to speed creep me :O. Thank you for reading this, first VOTW post hope i get the format right :]

Gardevoir-Mega @ Gardevoirite
Ability: Pixilate
EVs: 56 HP/ 252 SpA/ 200 Spe
Modest Nature
-Taunt
-Hyper Voice
-Psyshock
-Focus Blast

I'd like to use grandpa jam's MGarde spread, because it quickly became my new favorite, but really any works. Mega Garde seves as a one-time counter being able to switch in and avoid an OHKO from Thunderbolt even with a crit.

252+ SpA Mold Breaker Mega Ampharos Thunderbolt vs. 56 HP / 0 SpD Mega Gardevoir: 150-177 (51.5 - 60.8%) -- guaranteed 2HKO
252+ SpA Mold Breaker Mega Ampharos Focus Blast vs. 56 HP / 0 SpD Mega Gardevoir: 33-39 (11.3 - 13.4%) -- possible 8HKO

So it takes nothing from Dragon Pulse due to type, can live any Thunderbolt even with crit hax, and gets 8HKOed by Focus Blast, making it a one-time switch in. If Mega Ampharos uses Agility, then Gardevoir takes no damage and can live the next hit. If not for the solid 2HKO from Thunderbolt, I'd nominate it as a counter.

And then...

252+ SpA Pixilate Mega Gardevoir Hyper Voice vs. 4 HP / 0 SpD Mega Ampharos: 462-546 (143.4 - 169.5%) -- guaranteed OHKO

...yeah, that's pretty obvious. Anyway that's my first VOTW post so it's not too creative, literally went down the tier list till something sparked my intrest lol.

252+ SpA Mold Breaker Mega Ampharos Thunderbolt vs. 252 HP / 84+ SpD Clefable: 175-207 (44.4 - 52.5%) -- guaranteed 3HKO after Leftovers recovery
252 SpA Mold Breaker Mega Ampharos Thunderbolt vs. 252 HP / 84+ SpD Clefable: 160-189 (40.6 - 47.9%) -- guaranteed 3HKO after Leftovers recovery

It can come in on 3/4 moves w/o even getting scratched. Thunder Bolt does a lot of damage but it does not 2HKOs. It can easily keep healing until either your opponent switches or crits or paras :/ But if it comes on any other move, Clefable does this :
0 SpA Clefable Moonblast vs. 4 HP / 0 SpD Mega Ampharos: 182-216 (56.5 - 67%) -- guaranteed 2HKO

Clefable can set up on Mega Ampharos, if it switches in on any move other than Thunder Bolt and go home from there.

Wobbuffet @ Leftovers
Ability: Shadow Tag
EVs: 52 HP / 232 Def / 224 SpD
Bold Nature
- Encore
- Counter
- Mirror Coat
- Safeguard


Because Ampharos cannot boost its offense, Wobbufett's entry naturally is a death sentence to it since you can simply spam Mirror Coat without worry about Amphy boosting enough to break it; or so it seems. But in reality, it is not the case because Ampharos can take a Mirror Coat of Focus Blast. TBolt to FB to Tbolt will let Ampharos win the ordeal with Wobbs. Basically, if Wobbs comes in on Tbolt, then there will be a 50-50 of whether to Tbolt or FB; whether to Mirror Coat or Encore, which in turn makes it not a certain win for Wobbs. However, if Wobbs comes in on anything else, just spam Mirror Coat to your heart's content. Even if Ampharos decides to Agility stall, just wait until you are back to full HP from lefties, and then Encore that.

Is a check

Goodra @ Assault Vest
Ability: Sap Sipper
EVs: 240 HP / 252 SpA / 16 Spe
Modest Nature
- Draco Meteor / Dragon Pulse
- Fire Blast
- Sludge Bomb
- Earthquake

Goodra can switch into any opposing move and OHKO back with Draco Meteor (Dragon Pulse is a 2HKO). It is a check because it has 28,1% chance to be 2HKO'ed by Ampharos' Dragon Pulse. Otherwise, Focus Blast doesn't even 4HKO and Thunberbolt is 8HKO, making Goodra a good check/counter if well-played.

What Ampharos does

252+ SpA Mold Breaker Mega Ampharos Dragon Pulse vs. 240 HP / 0 SpD Assault Vest Goodra: 170-204 (44.6 - 53.5%) -- 28.1% chance to 2HKO
252+ SpA Mold Breaker Mega Ampharos Focus Blast vs. 240 HP / 0 SpD Assault Vest Goodra: 81-96 (21.2 - 25.1%) -- 0.1% chance to 4HKO
252+ SpA Mold Breaker Mega Ampharos Thunderbolt vs. 240 HP / 0 SpD Assault Vest Goodra: 45-54 (11.8 - 14.1%) -- possible 8HKO

What Goodra does

252+ SpA Goodra Draco Meteor vs. 4 HP / 0 SpD Mega Ampharos: 384-452 (119.2 - 140.3%) -- guaranteed OHKO
252+ SpA Goodra Dragon Pulse vs. 4 HP / 0 SpD Mega Ampharos: 252-296 (78.2 - 91.9%) -- 37.5% chance to OHKO after Stealth Rock

Ability: Synchronize

General answer to everything. Ampharos cant 2HKO Mew after rocks, and can recover of damage dealt. Mew can burn Ampharos and Roost/Soft-Boiled stall and do some residual damage with Knock Off to Ampharos it.

252+ SpA Mold Breaker Mega Ampharos Thunderbolt vs. 252 HP / 224+ SpD Mew: 142-168 (35.1 - 41.5%) -- guaranteed 3HKO after Stealth Rock and Leftovers recovery

Role: Hard Check / Soft Counter

252 SpA Mold Breaker Mega Ampharos Dragon Pulse vs. 0 HP / 0 SpD Landorus-T: 201-237 (63 - 74.2%) -- guaranteed 2HKO
252+ SpA Mold Breaker Mega Ampharos Dragon Pulse vs. 0 HP / 0 SpD Landorus-T: 220-259 (68.9 - 81.1%) -- guaranteed 2HKO
252 Atk Landorus-T Earthquake vs. 4 HP / 0 Def Mega Ampharos: 338-402 (104.9 - 124.8%) -- guaranteed OHKO
252 Atk Landorus-T Explosion vs. 4 HP / 0 Def Mega Ampharos: 283-334 (87.8 - 103.7%) -- 25% chance to OHKO (guaranteed OHKO after Stealth Rock)

With the above spread, Lando-T hits an effective Speed stat of 454, plenty enough to outspeed a +2 M-Amphy (378 and 414 for Modest and Timid, respectively). He can take a hit even after rocks and OHKO back with Earthquake (or Explosion if you're so inclined, although you need rocks up to guarantee it). Not a hard counter if M-Amphy has used Agility more than once though.

Klefki @ Light Clay
Ability: Prankster
EVs: 252 HP / 4 Def / 252 SpD
Careful Nature
- Reflect
- Light Screen
- Fairy Lock / Thunder Wave
- Play Rough

Klefki can't really switch into Thunderbolt or Focus Blast, but can obviously switch onto Dragon Pulse. Once in, it can set up a priority Light Screen and 2 or 3HKO Ampharos while taking somewhat minimal damage.

0 Atk Klefki Play Rough vs. 4 HP / 0 Def Mega Ampharos: 156-186 (48.4 - 57.7%) -- 92.6% chance to 2HKO
252+ SpA Mold Breaker Mega Ampharos Thunderbolt vs. 252 HP / 252+ SpD Klefki through Light Screen: 76-90 (23.8 - 28.3%) -- 94% chance to 4HKO

And if you do happen to switch it into Thunderbolt, it can still set up Light Screen before being KOed in order to support your next revenge killing attempt. The Fairy Lock / Thunder Wave choice falls to personal preference for other Klefki utility value; Fairy Lock ensures your opponent's Pokemon must stay in, allowing you to more reliably switch onto your next Pokemon, while Thunder Wave helps provide paralysis support overall.

Hope I'm not too late!

Here we have two Steel type checks for perusing pleasure, both of which assume Agility has been set up already:

Klefki @ Light Clay
Ability: Prankster
EVs: 252 HP / 4 Def / 252 SpD
Careful Nature
- Reflect
- Light Screen
- Fairy Lock / Thunder Wave
- Play Rough

Klefki can't really switch into Thunderbolt or Focus Blast, but can obviously switch onto Dragon Pulse. Once in, it can set up a priority Light Screen and 2 or 3HKO Ampharos while taking somewhat minimal damage.

0 Atk Klefki Play Rough vs. 4 HP / 0 Def Mega Ampharos: 156-186 (48.4 - 57.7%) -- 92.6% chance to 2HKO
252+ SpA Mold Breaker Mega Ampharos Thunderbolt vs. 252 HP / 252+ SpD Klefki through Light Screen: 76-90 (23.8 - 28.3%) -- 94% chance to 4HKO

And if you do happen to switch it into Thunderbolt, it can still set up Light Screen before being KOed in order to support your next revenge killing attempt. The Fairy Lock / Thunder Wave choice falls to personal preference for other Klefki utility value; Fairy Lock ensures your opponent's Pokemon must stay in, allowing you to more reliably switch onto your next Pokemon, while Thunder Wave helps provide paralysis support overall.

Metagross @ Assault Vest
Ability: Clear Body
EVs: 128 HP / 252 Atk / 128 Spe
Adamant Nature
- Meteor Mash
- Bullet Punch / Zen Headbutt
- Pursuit
- Earthquake

An unusual set, but effective, nonetheless. Can't really switch in on any of Mega Ampharos's moves and revenge kill, but barely avoids the 2HKO from Thunderbolt.

252+ SpA Mold Breaker Mega Ampharos Thunderbolt vs. 128 HP / 0 SpD Assault Vest Metagross: 141-166 (42.3 - 49.8%) -- guaranteed 3HKO

In return, it can 2HKO in response with Earthquake. If Mega-Ampharos has been weakened beforehand, a combination of Bullet Punch + Earthquake can clean it up.

252+ Atk Metagross Earthquake vs. 4 HP / 0 Def Mega Ampharos: 238-280 (73.9 - 86.9%) -- guaranteed 2HKO
252+ Atk Metagross Bullet Punch vs. 4 HP / 0 Def Mega Ampharos: 36-42 (11.1 - 13%) -- possible 8HKO

After SR, it is almost guaranteed that Metagross will get the KO on Ampharos. I'm not superbly sure on the other moves, but Pursuit is necessary to ensure it can function well outside of checking Ampharos by easily taking most attacks from and catching Lati@s. Meteor Mash is a strong STAB move that smashes through fairies like Clefable, while Bullet Punch more easily deals with Mega Diancie and is nice priority in general. Zen Headbutt turns this set into a solid check to Scarf Keldeo as well. The speed EVs ensure that this set outspeeds 68 Spe Heatran and can KO with Earthquake before it can burn with Lava Plume.

"From Saturday - Tuesday, each person can only nominate one Pokemon" (Taken from OP)

Do what you must to follow the rules.

Also, base Metagross is a shaky check since if M-Amphy already up an Agility, like you assumed, it can outspeed and 2HKO it after SR:

252+ SpA Mold Breaker Mega Ampharos Thunderbolt vs. 128 HP / 0 SpD Assault Vest Metagross: 141-166 (42.3 - 49.8%) -- 29.7% chance to 2HKO after Stealth Rock

Hard check
Gliscor @ Toxic Orb
Ability: Poison Heal
EVs: 244 HP / 192 SpD / 72 Spe
Careful Nature
- Earthquake
- Roost
- Swords Dance
- Knock Off

When invested, sp def Gliscor has enough bulk to tank dragon pulses and focus blasts, while thunderbolt is completely ineffective. Only modest amphy has a chance to 2hko with dragon pulse and that's only if it has used agility already, if it hasn't, then earthquake from Gliscor will easily outspeed and 2hko with earthquake despite the lack of attack investment.

 

[AM]

Don't really get the logic of saying "if it sets up an agility" when the whole point of this entry is implying that it's going to be getting one in the first place ._.

The logic with some of these submissions seems sort of counterproductive to the nature of what Agility Mega Ampharos would entail. I'd also, like the slashes suggest, just assume Timid being used before Modest.
