Other XY OU Victim of the Week [WEEK 6 (Read post #181)]

[Alter]

Just to clarify to everyone, it's not necessary to discuss Mega Luke in relation to its Nasty Plot set. As stated in the OP, these will only be done for sets, rather than the Pokemon as a whole. I've enjoyed reading the posts so far, though!

 

[Ash Borer]

Jaroda unfortunately cofagrigus can die to the burned crunch so it fails to qualify as a counter, as lucario will get away from the fight, although burned still alive.

 

[Terminate421]

Anything that can Thunderwave or Burn (On physical sets) is what is needed to stop him dead in his tracks.

for me, I often hit him on the first turn with Wil-O-Wisp Physical Defensive Dusknoir or Heliolisk with Thunderwave.

Technically, Lucario can get away from any fight if the user anticipates a counter/check. Unless the opponent has a cleric, a burnt Mega Luca isn't that threatening anymore and you can simply dispose of it later.

True, but in this case Cofagrigus dies. If Lucario uses close combat as Moltres switches in, then Moltres roosts as Lucario gets away Lucario has not made an impression on the opposing team, as well if it swords dances, then switches out when met with moltres, or attacks and dies it loses or does no damage. In the case of cofagrigus Lucario sets up a swords dance, kills Cofagrigus, then later in the match is subjected to healing wish or heal bell and it is ready to fight again. Moltres (w/o SR up) is a true counter, whereas Cofagrigus just dies while getting a burn off, valuable, but not a counter.

First off, Lucario isn't going to switch out; he's going to use Close Combat again since it does >50% and he's faster. Even if you were faster, Roost removes your Flying typing, meaning Close Combat does twice the damage and OHKOs your fire bird. Second, if you start bringing in switches and teammates to this, then technically nothing counters anything (with the possible exception of Pursuit).

Anyway, here's my idea:

Spiritomb @ Leftovers
Ability: Infiltrator (doesn't matter)
EVs: 252 HP / 252 Df / 4 Sp At
Bold Nature
- Will O' Wisp
- Pain Split
- Shadow Ball
- Memento/other

+2 252 Atk Mega Lucario Crunch vs. 252 HP / 252+ Def Spiritomb: 130-153 (42.7 - 50.3%) -- guaranteed 3HKO after Leftovers recovery

Spiritomb can win if it switches in on the first Swords Dance or a Close Combat. If it switches in on an already +2 boosted Crunch, you can get off a Pain Split and a Will O' Wisp, but you'll still fall. If you switch in on Swords Dance or Close Combat, you can Will O' Wisp the first turn, then Pain Split the second turn. At this point Lucario will be at about 44% health, and you'll be around 53% or a bit higher. You can then use Shadow Ball the next turn:

4 SpA Spiritomb Shadow Ball vs. 0 HP / 4 SpD Mega Lucario: 108-127 (38.4 - 45.1%) -- guaranteed 3HKO

Combined with the residual burn damage at the end of the turn, this will be enough to KO Lucario. Unfortunately Spiritomb will be at very low health after taking down Lucario, and wide-open for whatever comes in next due to its low speed, so you can either go for Memento to put a damper on whatever comes in next, or withdraw it and use Wish support to try and save it for later in the match. The final move can be substituted for whatever your team needs.

This Spiritomb isn't a perfect counter, but it can be a good check as long as you catch Mega Lucario before it boosts out of control.

Tangentially, Unaware Clefable can beat Mega Lucario as long as it has no Steel move through a combination of healing and Flamethrower, but loses otherwise.

I really don't understand what you're trying to say. There are two scenarios.

A) moltres switches in on swords dance. If it does, then lucario can either switch out and do no damage, or it can attack, and die to flamethrower
B) moltres switches in on Close Combat/any other attack.

In the case of B moltres takes ~28% from the strongest attack Lucario an throw at it, thus it is not in any danger of being killed, if it roosts in that case it is significantly slower than Lucario, and it does not take amplified damage from Close Combat, bringing it back to nearly full health. After this a moltres at ~90% or more is staring down a Lucario, it is plain to see who wins. If lucario switches out as Moltres roosts, then no damage was done. If Lucario swords dances then Moltres can attack and kill it. With no SR on the field, phys def moltres fully counters this Lucario, and can do so sustainably.

It's really frustrating to listen to people who don't read the posts theyre replying to, considering you thought that unboosted Lucario does over 50% to moltres, or you thought the point of this thread is to switch into +2 lucario, neither are true. It's also really frustrating to hear people use the word "counter" when they do not know the meaning. A counter must switch into an opponent, and no matter what they must KO the opponent should the opponent stay in. Because COfagrigus dies to 2 crunches after switching in it is not a counter. Yes, it burns lucario, yes this is valuable, however it doesnt KO it, thus it is not a counter. This is simply by definition.

To put it more accurately, in the worst case scenario factoring in Leftovers, Coff has a less than 50% chance to dying to the burned +2 Crunch. and this is if he Sword Danced on the switch, but you will always get a Burn off (unless you miss) and give him Mummy. I suppose because it does not counter 100% of the time it doesn't qualify though. Sableye however can come in on anything and get priority will o wisp off and then priority Recover stall. Fully invested Avalugg with Leftovers, even with Stealth Rock, can always OHKO with Earthquake. He can survive two CCs or even one +2 CC with Stealth Rock, and this is being weak to it! There's even the potential to counter the special sets with Sturdy and Mirror Coat or just EQ. Considering if no hazards one set can always kill either set is pretty good. Though I guess any Sturdy pokemon with EQ can do the same. If Avalugg runs Custap Berry though you can get off a priority Recover after killing Lucario though, so I would say Avalugg can reliably counter any physical set

 

[Don'tShootMeSanta]

If the goal is to find the most obscure check or counter, Steelix can eat close combat with sturdy and get a guaranteed OHKO back with earthquake, provided it gets a free switch in. This Lucario set can't beat Steelix one on one, so strictly by definition, Steelix checks him right?

 

[Onicon]

Only when assuming the opponent SD on the switch. If they fire off CC immediately, Steelix will be toast.

252 Atk Adaptability Lucario Close Combat vs. 252 HP / 252+ Def Steelix: 224-268 (63.27 - 75.7%) -- guaranteed 2HKO

Does not fare much better than Sawk.

Since we ran out of counters, let's try to check it some more.

Togekiss @ Leftovers
Ability: Serene Grace
EVs: 248 HP / 44 SAtk / 216 Def
Bold Nature
- Thunder Wave
- Air Slash
- Fire Blast
- Roost

Thank god Lucario does not gain SDef upon evolving. Thanks to that you can OHKO it quite easily with Fire Blast, unless it somehow runs more that 4 HP EVs. Unfortunately, Togekiss is not SR safe:

+2 252 Atk Adaptability Lucario Bullet Punch vs. 248 HP / 216+ Def Togekiss: 292-344 (78.28 - 92.22%) -- guaranteed 2HKO

Without SR, the worst thing that can happen is Fire Blast missing.

 

[Zebstrika]

There's a reason so many Lucario counters are SR weak. Fighting is resisted by Ghost, Psychic, Fairy, Flying and Bug. Ghost and Psychic can get covered by Crunch (or Shadow Ball if special) and Fairies get hit by steel stab. Which leaves flying and bug for fighting resists. Makes Stone Edge a nice trolly move on Lucario too.

Sitrus Berry Hawlucha might or might not be a little gimmicky (well, Hawlucha with a lot of speed and defense EVs works too but that's even more gimmicky) but it can counter Lucario as long as it switches in healthy and avoids Ice Punch. It can then outspeed Lucario if it is Jolly or Unburden activated (guaranteed if it switches on CC), take the Bullet Punch/Extreme speed and OHKO with HJK. Hawlucha with a different item still checks Lucario, and any Jolly Hawlucha can check a NP Lucario.

 

[Emerld Shuckle]

Dusclops (M) @ Eviolite
Ability: Pressure
EVs: 252 Def / 252 HP / 4 SDef
Bold Nature
- Will-O-Wisp
- Pain Split
- Substitute
- Night Shade

It can switch into anything this Lucario can put out and burn it back, then pain split some heal before switching out.
252 Atk Mega Lucario Crunch vs. 248 HP / 252+ Def Eviolite Dusclops: 78-92 (27.5 - 32.5%) -- guaranteed 4HKO
+2 252 Atk Mega Lucario Crunch vs. 248 HP / 252+ Def Eviolite Dusclops: 152-180 (53.7 - 63.6%) -- guaranteed 2HKO
+2 252 Atk burned Mega Lucario Crunch vs. 248 HP / 252+ Def Eviolite Dusclops: 76-90 (26.8 - 31.8%) -- guaranteed 4HKO
252 Atk burned Mega Lucario Crunch vs. 248 HP / 252+ Def Eviolite Dusclops: 39-46 (13.7 - 16.2%) -- possible 7HKO

As long as it doesn't switch into a +2 Crunch (which I don't think is possible given the situation), M-Lucario can't do anything to it.

 

[NotSoClutch]

Clefable @ leftovers/babiri berry
Ability: Unaware
EVs: 252 HP / 252 Df / 4 Sp At
Bold Nature
- Moonlight
- Flamethrower
- Reflect
- Cosmic Power

Since Unaware ignores any of the opponents boosts, clefable is able to switch in on any attack other than Bullet Punch. The Babiri Berry helps alleviate the first possible bullet punch.

Close Combat 31.4 - 37.3%
Bullet Punch 21.3 - 25.3%

After Switching in, set up a reflect. Worst case scenario, Clefable has lost it's berry and will take another bullet punch and be at about 25% health before either using moonlight or reflect.

Bullet Punch 42.6 - 50.7%

After a reflect is up
Bullet Punch 21.3 - 25.3%

After one cosmic power
Bullet Punch 28.4 - 34.5%

Clefable can also stall Lucario with moonlight and leftovers as Bullet Punch will only do 42.6 - 50.7% which can be out gained by leftovers and moonlight respectively until a reflect can safely be put up.

Flamethrower will then be able to take Lucario out in two turns after setting up.
4 SpA Clefable Flamethrower vs. 0 HP / 0 SpD Mega Lucario: 168-198 (59.7 - 70.4%) -- guaranteed 2HKO

Edit: This set is a bit gimmicky, but I've actually used it on a legitimate team before with mild success and it does stop lucario pretty well.

 

[NotSoClutch]

Someone should try an azumarill set as well. I bet it would could work fairly well.

 

[The Great Gastly]

Stealth Rock weakness aside, I've been using SansNickel's Entei from his "Under Pressure" team (http://www.smogon.com/forums/threads/under-pressure-stall-in-ou-peak-8.3496835/). Given the definition of check, it seems to work.

Entei@Choice Band

Adamant Nature
-Bulldoze

-Stone Edge

Calcs

+2 252 Atk Lucario Close Combat vs. 4 HP / 252 Def Entei: 306-361 (82.2 - 97%) -- guaranteed 2HKO
(306, 310, 313, 318, 321, 324, 328, 331, 336, 339, 342, 346, 349, 354, 357, 361)

252+ Atk Choice Band Entei Sacred Fire vs. 0 HP / 0 Def Lucario: 662-780 (235.5 - 277.5%) -- guaranteed OHKO

Another set from the Entei thread would work as well:

I know we're only discussing countering a particular set, but I'm curious if an Assault Vest > Choice Band could allow it to combat Luke's NP set too. CB seems superfluous to ohko, so added utility would be cool. :O

 

[Baharoth]

Someone should try an azumarill set as well. I bet it would could work fairly well.

Had the same idea and calculated it just now

Azumarill @ leftovers
252 HP 200 atk 56 def
adamant
Aquajet
Waterfall
Superpower
Play Rough

after factoring in SR dmg and lefty recovery it will be @ 379 HP if i am not mistaken, the most Lucario can do to it are 375 points of dmg while it can ko back 100% of the time with Superpower. If Lucario goes for an attack move instead of SD its even easier due to more lefty recovery. Dont know how usefull that set is outside of countering Lucario though...

 

[Liquidocelot]

Wobbuffet @ Leftovers
Ability: Shadow Tag
EVs: 4 SDef / 252 HP / 252 Def
Bold Nature
- Counter
- Encore
- Mirror Coat
- Tickle

Before i describe why this set counters mega lucario lets look at some calcs.

252 Atk Mega Lucario Crunch vs. 252 HP / 252+ Def Wobbuffet: 190-224 (32.5 - 38.3%) -- 1.9% chance to 3HKO after Leftovers recovery

252+ Atk Adaptability Mega Lucario Close Combat vs. 252 HP / 252+ Def Wobbuffet: 156-184 (26.7 - 31.5%) -- 24.1% chance to 4HKO after Leftovers recovery

252+ Atk Mega Lucario Crunch vs. 252 HP / 252+ Def Wobbuffet: 208-246 (35.6 - 42.1%) -- 89% chance to 3HKO after Leftovers recovery

Looking at this wobuffet can take anything but a +2 attack on the switch and a adamant +2 close combat on the switch other wise it can switch in on the boost take a hit and counter back or encore on the next boost with some prediction this allows him to beat any physical mega luke set in the game with ease and there is no switching out either.

 

[Cubia]

I can't believe no one has mentoned the most obvious counter, Gliscor. there is almost nothing mega luke can do to Gliscor while it can guaranteed 2HKO back with an earthquake every single time. the closest it gets is CCing it to death, and even that wont happen.
+2 252 Atk Adaptability Mega Lucario Close Combat vs. 252 HP / 184+ Def Gliscor: 183-216 (51.6 - 61%) -- 53.1% chance to 2HKO after Poison Heal
0 Atk Gliscor Earthquake vs. 0 HP / 0 Def Mega Lucario: 230-272 (81.8 - 96.7%) -- guaranteed 2HKO

But moving past the obvious, if we are looking for obscure counters, you can pull a really low tiered pokemon up to deal with physical Lucario. It turns out that a Physically Defensive Vespiqueen can take anything from Lucario and defensive boost and heal order/roost back to full health even with stealth rocks up(even though it strips half of the bee's health). It may seem weird, but I have had decent success on many teams with an Infestation/Toxic Vespiqueen.


(Vespiquen) (F) @ Leftovers
Ability: Pressure
EVs: 252 Def / 252 HP / 4 SDef
Bold Nature
- Infestation
- Heal Order/Roost
- Defend Order
- Toxic

The plan is, you swap in on something that cant hurt you(Lucario), infestation lock them in with you, and spam heal and defend order for as long as you want, to get beefy enough to defensively sweep by the time they are untrapped. Lucario can't hurt the bee much on switch in, and after a defend order, he can do even less. It works surprisingly well I've found.

Some numbers:
w/ stealth rocks
252 Atk Adaptability Mega Lucario Close Combat vs. 252 HP / 252+ Def Vespiquen: 50-59 (14.5 - 17.1%) -- 4.7% chance to 3HKO after Stealth Rock

+2 252 Atk Adaptability Mega Lucario Bullet Punch vs. 252 HP / 252+ Def Vespiquen: 136-160 (39.5 - 46.5%) -- guaranteed 3HKO

Note that I even forgot to put leftovers in my calcs

and if you can get your defend order stacks up, then you can slowly kill him with the residual damage from infestation, while staying healthy.

Actually, Gliscor will OHKO it because of the defense drops of Close Combat.

Gliscor is the entire reason lucario carries ice punch which I believe OHKOs and vespiquin also gets demolished by ice punch as well.

Personally, a pokemon that can be 2HKO'd by close combat 53% of the time doesn't seem like an amazing counter, though it might be as good as you get against a monster like Mega-Lucario. In addition, although its not common, Lucario can carry ice punch, which 2HKO's gliscor without a boost. It also falls to the special variant which means you have to run another counter to that set.

Not to mention Gliscor is doomed if it swaps into Mega Luca while it sets up. Most of them run ice punch to deal with gliscor specifically (and given the chance, landorus, dragonite and garchomp as well bar scarfed variants).

I know we're only discussing countering a particular set, but I'm curious if an Assault Vest > Choice Band could allow it to combat Luke's NP set too. CB seems superfluous to ohko, so added utility would be cool. :O

I understand what you mean, but I put that particular set because it's the only time I've ever used Entei so it was the only one I was familiar with. The other set I found with just a glance at Entei's thread. There is an Assault Vest set listed there, but I'm not sure if it's worth it without doing any calculations. Given that a neutral Entei's max DEF reaches 329 (you have to go Adamant if you want Extreme Speed) and his max neutral SpDEF reaches 373 with the Vest, I imagine the outcome would be slightly better than the physical variant, and possibly a better choice if we weren't discussing physical Lucario.

But moving past the obvious, if we are looking for obscure counters, you can pull a really low tiered pokemon up to deal with physical Lucario. It turns out that a Physically Defensive Vespiqueen can take anything from Lucario and defensive boost and heal order/roost back to full health even with stealth rocks up(even though it strips half of the bee's health). It may seem weird, but I have had decent success on many teams with an Infestation/Toxic Vespiqueen.

I love that someone's actually using Vespiquen. I have a few things to say about the Vespiquen vs M-Lucario matchup though.

First off, Vespi's always going to lose to special Luke. I was originally going to reply suggesting a specially defensive spread to dodge the 2hko from Flash Cannon while still having enough bulk to deal with Espeed, but I realized if you switch in on the NP Luc's just going to outspeed and 2hko you before you can do anything anyway. Regardless, the fact that Vespi only beats phys Luke would in itself be enough for me to not consider it for the job.

Revisiting physical Luke vs physically defensive Vespiquen: let's assume you switch Vespiquen in while Luke SDs. If that Luke is running Ice Punch, you're getting outsped and 2hko'd just like Flash Cannon. If he's running Stone Edge (I wouldn't count on it, but it could happen) it's checkmate from the start. If it isn't, you have another problem: you're behind it in the setup race right off the bat and it sets up twice as fast as you do. By the time you get to +1 he's at +4, and if you try for +2 he'll be at +6. +6 Luke actually can't 2HKO +2 Vespi, HOWEVER anything he can do aside from Close Combat will OHKO at that point if it crits, and he's going to have at least eight turns to try before Infestation will KO him (probably more than that, considering you'll be juggling protect/heal orders on top of trying to keep Infestation up). Crunch can also potentially score Luke defense drops, undoing a turn of setup.

On the other hand, considering how much free setup you're giving Luke, if you ran Confuse Ray or Swagger over Toxic he may very well just blow himself up. Confusion's not something worth relying on, but with Infestation preventing Luke from switching out and the relative ease you can take most of his attacks with, it makes the matchup look much nicer for Vespi.

All in all though, I wouldn't consider her for the job. She loses to special Luke, she loses to Ice Punch, she loses to Stone Edge, and you don't know if any of those things exist until they happen, and at that point it's too late.

I've been using Bulky DD Gyarados on one of my teams; although for some reason that team hasn't faced Mega Luke yet, I ran the calcs and found that it can take on Physical Luke pretty well:

Gyarados @ Leftovers
Ability: Intimidate
EVs: 120 HP / 72 Atk / 100 Def / 216 Spd
Adamant Nature
- Substitute
- Dragon Dance
- Waterfall
- Bounce / Earthquake

+1 252 Atk Adaptability Mega Lucario Close Combat vs. 120 HP / 100 Def Gyarados: 153-181 (42.3 - 50.1%) -- guaranteed 3HKO after Leftovers recovery (after Intimidate)
+1 252+ Atk Adaptability Mega Lucario Close Combat vs. 120 HP / 100 Def Gyarados: 168-198 (46.5 - 54.8%) -- 10.9% chance to 2HKO after Leftovers recovery

That's the most powerful attack Mega Luke can throw against Gyarados. In return, Gyara outspeeds and OHKOs with Waterfall after a DD and the Def drop from CC. Earthquake will KO after the CC Def drop.

72+ Atk Gyarados Earthquake vs. -1 0 HP / 0 Def Mega Lucario: 340-400 (120.9 - 142.3%) -- guaranteed OHKO
+1 72+ Atk Gyarados Waterfall vs. -1 0 HP / 0 Def Mega Lucario: 306-360 (108.8 - 128.1%) -- guaranteed OHKO
