So here's a stall team I've been working on the past couple of weeks, for an event I'm participating in along with my friends. The restriction is that our teams must contain at least 3 pokemon that share a specific type. In my case, I was lucky and got the Steel type. So, keeping that restriction in mind, I started the team building. First, a preview of the final team, and then I'll go into the building process.






So, the team started with these two, as I really wanted to use them. Mirror Coat Alommoola and Stalltini. So, simple, I put them on the team.


Then, I wanted something to beat Aegislash (since he wasn't banned yet at the time) and also something to deal with Landorus, given that he's been a pain for my stall teams to usually handle. So I settled on SpD Gliscor. But Gliscor loses to HP Ice from Landorus, so I decided to add another strong check and pokemon that I was interested in trying out in Bronzong.




Next, I needed two more steel types, and I hadn't used a Mega yet. Given how my normally physically bulky pokemon are both running SpD variants I went with Skarmory, which gave me access to Defog support as well. Finally, a Steel type, and potential Mega. Scizor is definitely the better Mega, but I needed Stealth Rocks, and Scizor needs to give up coverage to be a win condition since it would need Swords Dance and Roost. So I settled on Mega Aggron, who doesn't need setup to hit fairly hard and is incredibly bulky even if I invest in attack. Plus he gets SR so...






At this point the team was testing alright, but I noticed a huge weakness to Rotom-W. I didn't have a cleric, and my two burn absorbers don't like taking Hydro Pumps. Nothing really threatened him either, except Victini hitting it on a switch in. So it was at this point I started searching for a lure that could beat Rotom-W and still work on stall. I settled on Energy Ball Jirachi. I knew it was bad but I figure it has enough utility as a Wish passer to make up for it. So I swapped Mega Aggron out. Now though, I had 3 Psychic types and no Ghost/Dark resist, so I swapped Gliscor for Krookodile. Aegislash was banned and Bronzong dealt with any non-Gravity Landorus just fine, so Gliscor wasn't needed. Krookodile gives me another solid physical wall, keeps Gliscor's access to Knock Off and Earthquake, and can even use Taunt and Stealth Rock.






After testing the team a bit more, I found Rotom-W was still a huge pain to deal with. My "lure" in Jirachi didn't really work. You'd think a pokemon that is resistant to Iron Head and immune to thunder wave, while also being a generally bulky pokemon would be a great switch in to Jirachi but Rotom-W generally didn't come in at all, even if I didn't reveal Energy Ball. So I came up with a new lure, one that was surefire to get Rotom to switch in. Power Herb Solar Beam Heatran. At this point though, I was also really hurting for a cleric, and while having Heatran was nice, I still didn't have a good switch in to Rotom. So I decided to look for a grass type cleric and settled on Shaymin. I chose Shaymin over Celebi (who is generally better) because Celebi's psychic typing would be a hindrance to the team.






In the end, I decided that Celebi is better than Shaymin because of being able to take on Keldeo much easier. The Ghost/Dark weaknesses really hurt, but other than random Knock Off users or STAB users, there's hardly any pokemon that use those moves for coverage. Celebi has been testing well, since Keldeo's rise to S rank on the viability thread has been only increasing his popularity.






So here's where the team stands currently.
So without further ado, here's the sets:

Alomomola @ Leftovers
Ability: Regenerator
EVs: 252 HP / 4 SpA / 252 SpD
Calm Nature
IVs: 0 Atk
- Protect
- Wish
-
- Mirror Coat
God do I love the Fish. Chansey 2.0 here has some important distinctions that separate it from its fatter cousin and her older sister, Blissey. The first is a better typing. Sure, Fish has more weaknesses than Chansey, but more importantly, Fish also has resistances, namely Water, Steel, Fire and Ice. The second thing is that Fish is a much better Wish passer than Chansey. Chansey's are legitimately huge, but Alomomola's aren't slouches either, healing for a good 267 HP, which is enough to get most pokemon back up to full if they can survive the hit coming in. What really makes Fish shine as a Wish passer is Regenerator, which lets it come in, sponge a hit, Wish on the switch, then switch out and in most cases not even have taken any damage after all is said and done. Regenerator + Leftovers means that one hit has to do more than 40% to even scratch the Fish after it switches. Now, going Calm with Mirror Coat might seem strange, given that Fish is known for being a physical wall, but Alomomola makes a great Mirror Coat user. People don't expect it, very little can actually OHKO this thing, and Mirror Coat deals so much damage it's actually kinda ridiculous. Wish and Protect are pretty obvious and don't need explaining. Toxic is there to better deal with threats like Hydreigon and Charizard X.
A typical Rotom's Volt Switch, for example, will OHKO any pokemon that comes in that isn't a dark type or has less than base 80 fully invested HP.
4 SpA Rotom-W Volt Switch vs. 252 HP / 252+ SpD Alomomola: 182-216 (34 - 40.4%) -- 38.1% chance to 3HKO after Leftovers recovery
(182, 182, 186, 188, 192, 192, 194, 198, 198, 200, 204, 206, 206, 210, 212, 216)
So let's take 182, the lowest damage roll. That's 34% to Fish (not enough to actually hurt it once it switches out), and 364 damage to the switch in with Mirror Coat. That happens to be exactly Mega Venusaur's maximum HP if fully invested. So a Volt Switch from Rotom-W into Mega Venusaur will pretty much always OHKO Venusaur. As if that wasn't enough, it can beat Yzard in the sun in a pinch!
252 SpA Mega Charizard Y Fire Blast vs. 252 HP / 252+ SpD Alomomola in Sun: 179-211 (33.5 - 39.5%) -- 20% chance to 3HKO after Leftovers recovery
Assuming 39.5% damage, after leftovers that leaves Fish at 67%. Protect for the leftovers recovery. 73%. Then Solar Beam hits.
252 SpA Mega Charizard Y Solar Beam vs. 252 HP / 252+ SpD Alomomola: 348-410 (65.1 - 76.7%) -- guaranteed 2HKO after Leftovers recovery
(348, 352, 356, 360, 364, 368, 372, 376, 380, 384, 388, 392, 396, 400, 404, 410)
That's a pretty good chance of surviving, given that Mola will have 390 HP...and that was with a max damage roll Fire Blast too. Mirror Coat obviously wipes the floor with Yzard afterwards. Focus Blast does a little bit less damage (about 1-2% less on either end of the rolls) than Fire Blast, so nothing changes there. Flamethrower variants lose as max damage rolls from both attacks will leave Mola at 3% HP after everything is said and done. Fish loses to Modest variants though.
It's also fun to make people just instantly quit after getting hit by Mirror Coat

4 SpA Rotom-W Volt Switch vs. 252 HP / 252+ SpD Alomomola: 182-216 (34 - 40.4%) -- 38.1% chance to 3HKO after Leftovers recovery
(182, 182, 186, 188, 192, 192, 194, 198, 198, 200, 204, 206, 206, 210, 212, 216)

Assuming 39.5% damage, after leftovers that leaves Fish at 67%. Protect for the leftovers recovery. 73%. Then Solar Beam hits.
252 SpA Mega Charizard Y Solar Beam vs. 252 HP / 252+ SpD Alomomola: 348-410 (65.1 - 76.7%) -- guaranteed 2HKO after Leftovers recovery
(348, 352, 356, 360, 364, 368, 372, 376, 380, 384, 388, 392, 396, 400, 404, 410)

Victini @ Leftovers
Ability: Victory Star
EVs: 140 HP / 252 Atk / 116 Spe
Adamant Nature
- V-create
- Bolt Strike
- Taunt
- Will-O-Wisp
This is my own take on the Stalltini set. Generally Stalltini runs 224 HP / 252+ Atk / 32 Spe, and I originally ran that spread. It outspeeds Adamant Bisharp and everything slower, and lets Victini burn them. However, I decided going up to 56 speed to outspeed Adamant Mega Heracross was prudent, given how much of a pain Mega Hera will be to deal with. I then bumped the speed up to 116 to outspeed Jolly Breloom (technically 108 speed deals with it, but as this is an in-game team the battles will be at lvl 50, where 116 is needed to outspeed). This change came about after having faced literally 6 Breloom leads in a row...5 of which were SubSeed with Poison Heal. So, the speed lets me outspeed and burn Breloom before it can set up Substitute or Spore and cripple it, regardless of whether or not it is Poison Heal or Technician. Taunt lets Victini beat a lot of slower pokemon who think they can use it as setup bait, while V-Create is just an insane nuke, and Bolt Strike is very good to hit the water types that think they can stomach a V-Create.
Victini is also a great answer to Mega Mawile, Mega Medicham, and Mega Gardevoir depending on her coverage and it's health. it resist all of their STAB attacks, while either crippling with Will-o-Wisp or killing outright.
Besides being a good replay of the team in general, this replay shows how Victini can deal with Mega Mawile, even SubPunch ones.
http://replay.pokemonshowdown.com/ou-149685785
Now, some of you are probably thinking it was an act of desperation, risking Victini like that, but the odds were quite firmly in my favor.
252+ Atk Huge Power Mega Mawile Sucker Punch vs. 140 HP / 0 Def Victini: 330-390 (87.7 - 103.7%) -- 25% chance to OHKO
75% chance of crippling Mega Mawile? Sounds good to me, especially since I outspeed even after the speed drop and can land the burn regardless of what he does. Victini isn't a counter, more of a hard check, and the Pixie definitely needs entry hazards dealt with, but I can sac Skarmory to clear them pretty easily against a Mawile.
No replays vs Mega Medicham or Gardevoir, but...
252 Atk Pure Power Mega Medicham High Jump Kick vs. 140 HP / 0 Def Victini: 177-208 (47 - 55.3%) -- 17.2% chance to 2HKO after Leftovers recovery
Adamant is a 91% chance of 2HKO though, so it's risky. That being said, Will-O-Wisp cripples it and V-Create actually OHKOs it.
252+ Atk Victini V-create vs. 0 HP / 0 Def Mega Medicham: 307-363 (117.6 - 139%) -- guaranteed OHKO
252 SpA Pixilate Mega Gardevoir Hyper Voice vs. 140 HP / 0 SpD Victini: 114-135 (30.3 - 35.9%) -- guaranteed 4HKO after Leftovers recovery
If it runs shadow ball though...
252 SpA Mega Gardevoir Shadow Ball vs. 140 HP / 0 SpD Victini: 210-248 (55.8 - 65.9%) -- guaranteed 2HKO after Leftovers recovery
But, I can switch into Hyper Voice then comfortably take a shadow ball, followed up by:
252+ Atk Victini V-create vs. 4 HP / 0 Def Mega Gardevoir: 382-450 (137.4 - 161.8%) -- guaranteed OHKO
As always with Victini, entry hazards do compromise it's bulk quite a bit, but there's always the option of Wish passing to it to take the hit + rocks then come out all squeaky clean at full health and ready to deal with the opposing pokemon.

Bronzong @ Leftovers
Ability: Levitate
EVs: 252 HP / 92 Atk / 164 SpD
Sassy Nature
IVs: 0 Spe
- Gyro Ball
- Rock Slide
- Stealth Rock
- Zen Headbutt/Protect
Originally I ran Assault Vest Bronzong with Hidden Power Ice to deal with Landorus-I better. The spread + Assault Vest made Focus Blast a 20% chance to 3HKO with SR up...meaning that I can switch into any attack (barring Gravity) and 2HKO it with Hidden Power Ice. Then I realized that Gyro Ball is a 91% to 2HKO without any prior damage to Landorus, and HP Ice actually loses if it's Calm Mind Landorus. So this means I had a "free" moveslot. Originally I ran Stealth Rocks on Heatran, but I was hurting for a phazing move somewhere, so I switched Bronzong to leftovers and gave it Stealth Rock in the free slot. Landorus is a bit more of an issue now, since Focus Blast is a guaranteed 3HKO, but if Bronzong switches into Earth Power (without Gravity up, of course), Psychic, Sludge Wave or Hidden Power Ice I win, and if a single Focus Blast out of the three misses I win. I'll take those odds. Gyro Ball is STAB and Bronzong's strongest attack by far. Rock Slide is to help against Flying types that like to switch into Bronzong (Talonflame), or that I like to switch Bronzong into (Thundurus and Pinsir). Zen Headbutt is another STAB that happens to hit Mega Venusaur fairly hard, though it really only beats offensive variants or variants that lack Synthesis. It also nails Keldeo on switches. Protect allows me to get Leftovers recovery and offers me another pokemon to swap to for Toxic stalling. I'm undecided on which I like more.
252 SpA Life Orb Sheer Force Landorus Focus Blast vs. 252 HP / 164+ SpD Bronzong: 142-168 (42 - 49.7%) -- guaranteed 3HKO after Stealth Rock and Leftovers recovery
92 Atk Bronzong Gyro Ball (131 BP) vs. 4 HP / 0 Def Landorus: 154-183 (48.1 - 57.1%) -- 91% chance to 2HKO
Like I said earlier, I'll take those odds. It's not called Focus Miss for nothing. Besides, Fish takes about 55% from Earth Power and Mirror Coat will obviously kill it in return afterwards.
Bronzong, however, also deals with Mega Pinsir, and it's the main reason for that attack investment and Rock Slide being on the set.
+2 252 Atk Mega Pinsir Close Combat vs. 252 HP / 0 Def Bronzong: 262-309 (77.5 - 91.4%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
That means I can switch in on the Swords Dance and still live the strongest hit Pinsir can throw at me.
Meanwhile,
92 Atk Bronzong Rock Slide vs. 0 HP / 4 Def Mega Pinsir: 184-220 (67.8 - 81.1%) -- guaranteed 2HKO
(184, 188, 188, 192, 192, 196, 200, 200, 204, 204, 208, 208, 212, 212, 216, 220)
Assuming Pinsir switched into SR, then Mega Evolved, that puts it at 204 HP...so I have about a 50% chance to beat it with Rock Slide. Not the best odds, but I can't really improve them much, and I do have Skarmory with Rocky Helmet in the back to help. My main draw to Bronzong especially was how some higher end players were saying he could deal with both Mega Pinsir and Landorus in the same set...and it turns out he's basically a strong check to both, but not really a counter to either. Still, he's been performing well enough that while I do have my doubts about it being a shaky answer, I enjoy having him on the team.

Skarmory @ Rocky Helmet
Ability: Sturdy
EVs: 252 HP / 204 Def / 52 Spe
Impish Nature
- Defog
- Roost
- Brave Bird
- Taunt
Pretty standard Skarmory, though there are some important changes. I'm loving Taunt on Skarmory, though I do miss Whirlwind, since it lets me deal with defensive pokemon better. I'm also running a little bit more speed than normal, this is to outspeed Adamant 4 Spe Mega Heracross (at lvl 50 of course). It's such a small investment over the standard 24 Spe that I feel confortable making the switch, especially as Brave Bird is a OHKO on 252 HP Mega Heracross. Granted, that Heracross set isn't common in high level play but it is common in lower level play, which is where I am on the ladder, technically. Defog and Roost need no explaining. I prefer Brave Bird to Counter as it lets me be a little more proactive with Skarmory, and not be entirely reliant on my opponent to deal damage. Also, Counter is really, really awful against Mega Heracross since it only does damage based on the last hit of Rock Blast or Pin Missile, not all 5 hits combined.
0 Atk Skarmory Brave Bird vs. 252 HP / 0 Def Mega Heracross: 204-244 (109 - 130.4%) -- guaranteed OHKO
yeah that's about all I got for calcs. Skarmory is a pretty standard old hat and at this point most everyone knows what it can do
yeah that's about all I got for calcs. Skarmory is a pretty standard old hat and at this point most everyone knows what it can do

Heatran @ Power Herb
Ability: Flash Fire
EVs: 252 HP / 132 SpA / 124 Spe
Modest Nature
- Lava Plume
- Solar Beam
- Roar
- Taunt
Ah, Heatran. This set may look really weird, but the EVs are optimized for lvl 50 play. Lava Plume is standard STAB, Solar Beam is for killing Rotom-W (and non AV Azumarills that are common switch ins as well), Roar is for phazing and Taunt is just generally disruptive. I've found that while I have missed leftovers recovery on Heatran, he still has great bulk just with HP investment, so I'm pretty comfortable using this set. This was the best lure I could come up with for a Stall team.
Alright, let's do some dirty deals here. Assuming the standard 248 HP / 212+ Def / 44 Rotom-W, who runs that speed to outspeed and burn Jolly Azumarill, my EV spread lets me outspeed Rotom-W by 1 point. Next, the actual damage calcs.
132+ SpA Heatran Lava Plume vs. 248 HP / 0 SpD Rotom-W: 33-39 (21.1 - 25%) -- possible 5HKO after Leftovers recovery
not very impressive...but then:
132+ SpA Heatran Solar Beam vs. 248 HP / 0 SpD Rotom-W: 132-156 (84.6 - 100%) -- 6.3% chance to OHKO
So, assuming the absolute lowest damage roll on both attacks, no SR on his side, and Rotom-W holding Leftovers, the wombo combo does 99% So yeah, chances are Heatran will break right through the Washing Machine. And even if it manages to live (and therefor go up to 7% HP at the end of the turn) I outspeed and KO it with Lava Plume anyways.
0 SpA Rotom-W Hydro Pump vs. 252 HP / 0 SpD Heatran: 126-150 (63.6 - 75.7%) -- guaranteed 2HKO after Stealth Rock
I even live the Hydro Pump he fires off after my Solar Beam just barely fails to kill him. Note that these particular calcs were done at lvl 50, at lvl 100 it's 97% rather than 99%, not that it changes much of anything
132+ SpA Heatran Lava Plume vs. 248 HP / 0 SpD Rotom-W: 33-39 (21.1 - 25%) -- possible 5HKO after Leftovers recovery
not very impressive...but then:
132+ SpA Heatran Solar Beam vs. 248 HP / 0 SpD Rotom-W: 132-156 (84.6 - 100%) -- 6.3% chance to OHKO

0 SpA Rotom-W Hydro Pump vs. 252 HP / 0 SpD Heatran: 126-150 (63.6 - 75.7%) -- guaranteed 2HKO after Stealth Rock
I even live the Hydro Pump he fires off after my Solar Beam just barely fails to kill him. Note that these particular calcs were done at lvl 50, at lvl 100 it's 97% rather than 99%, not that it changes much of anything

Celebi @ Leftovers
Ability: Natural Cure
EVs: 252 HP / 4 SpA / 252 SpD
Calm Nature
- Recover
- Heal Bell
- Giga Drain
- Psychic
Celebi basically deals with everything Shaymin did, except for Hydreigon, but deals better with Keldeo in return. Rotom-W still doesn't bug Celebi at all (except for random Shadow Ball Rotoms...), it's still a grass type cleric, and Recover is definitely better than Synthesis, having more PP and being more reliable. Giga Drain is STAB and heals Celebi extra (Shaymin could have done the same but the extra power on Seed Flare was too strong to give up). Psychic is another STAB that hits Keldeo harder, lets Celebi actually hurt Mega Venusaur, which Shaymin couldn't.
252 SpA Life Orb Thundurus Hidden Power Ice vs. 252 HP / 252+ SpD Celebi: 120-143 (29.7 - 35.3%) -- 18.1% chance to 3HKO after Stealth Rock and Leftovers recovery252 SpA Life Orb Thundurus Thunderbolt vs. 252 HP / 252+ SpD Celebi: 66-79 (16.3 - 19.5%) -- possible 7HKO after Stealth Rock and Leftovers recovery
Even if Thundurus has Nasty Plot, it needs Life Orb to be able to beat Celebi at +2
+2 252 SpA Thundurus Hidden Power Ice vs. 252 HP / 252+ SpD Celebi: 184-218 (45.5 - 53.9%) -- 2% chance to 2HKO after Leftovers recovery
Celebi has the same bulk as Shaymin did, so the calcs didn't change, but Celebi has a harder team dealing with Thundurus since it doesn't have Toxic and has to rely on Life Orb recoil to really stall it out. However, switching in Alomomola on a HP Ice or HP Flying should allow it to take the follow up Thunderbolt and Mirror Coat it.
252 SpA Choice Specs Keldeo Hydro Pump vs. 252 HP / 252+ SpD Celebi: 96-114 (23.7 - 28.2%) -- possible 5HKO after Leftovers recovery
252 SpA Choice Specs Keldeo Secret Sword vs. 252 HP / 0 Def Celebi: 103-122 (25.4 - 30.1%) -- 0.3% chance to 4HKO after Leftovers recovery
252 SpA Choice Specs Keldeo Icy Wind vs. 252 HP / 252+ SpD Celebi: 130-154 (32.1 - 38.1%) -- 0.9% chance to 3HKO after Leftovers recovery
4 SpA Celebi Psychic vs. 0 HP / 4 SpD Keldeo: 212-252 (65.6 - 78%) -- guaranteed 2HKO
4 SpA Celebi Psychic vs. +1 0 HP / 4 SpD Keldeo: 144-170 (44.5 - 52.6%) -- 18.8% chance to 2HKO
So yeah, Keldeo is pretty well taken care of, even SubCM Keldeo. As for Mega Venusaur...
252+ SpA Mega Venusaur Sludge Bomb vs. 252 HP / 252+ SpD Celebi: 222-264 (54.9 - 65.3%) -- guaranteed 2HKO after Leftovers recovery
4 SpA Celebi Psychic vs. 252 HP / 4 SpD Mega Venusaur: 168-198 (46.1 - 54.3%) -- 49.2% chance to 2HKO
So while Celebi isn't an answer to Mega Venusaur, it can win a 1v1 with any variant if the Venusaur switches into Psychic. It won't always win, bad rolls happen, but...it can do it.
Big Threat:

Finally, here are some replays and an importable of the team. Excuse the low ELO of these, I'm not very high up on the ladder, as you can see. Also some were on an alt that's lower on the ladder still.
