Overview
########

Rotom-W is one the best bulky pivots in the tier, thanks to its typing, decent stats, and movepool. Its Electric / Water typing is very useful for taking on powerful and common threats in the tier such as Mega Pinsir, Talonflame, and Azumarill. Levitate in conjunction with its Water typing allows it to check common Ground-types as well, such as Landorus-T, Hippowdon, and even non-Substitute Garchomp. Furthermore, it has the perfect support moves to fit its role, with STAB Volt Switch providing valuable momentum, Pain Split healing it while damaging the opponent, Trick to cripple walls; (most notably Chansey, a common switch-in to Rotom-W, and Will-O-Wisp to threaten physical attackers.

Unfortunately, it is Rotom-W's strengths that have made the metagame adapt around it. While Rotom-W has an amazing typing, its low HP means its bulk isn't as naturally high as it might like. Teams that use Rotom-W to check the previously mentioned Pokemon will often find that it's hard-pressed to cover them all, considering its only recovery move is Pain Split or the unreliable Rest. However, with even the slightest amount of support, Rotom-W can truly shine in this metagame.

Defensive
########
move 1: Volt Switch
move 2: Hydro Pump
move 3: Will-O-Wisp
move 4: Pain Split / Rest
ability: Levitate
item: Leftovers / Chesto Berry
nature: Bold
evs: 248 HP / 216 Def / 44 Spe

Moves
========

This set is the perfect combination of defensive and offensive presence, making it a perfect Pokemon for balanced teams. Rotom-W has access to STAB Volt Switch, which allows it to assume the role of a defensive pivot against Pokemon like Mega Pinsir, Talonflame, and Azumarill. This means that even if the opponent has a Latias, Mega Venusaur, or another counter in the wings, Rotom-W can simply Volt Switch into another Pokemon that has a better match-up against said counter. Hydro Pump is useful for hitting the Ground-types that Rotom-W can usually switch into with ease, namely Hippowdon and Landorus-T. Neither of these Pokemon can take a Hydro Pump well, nor will they appreciate a burn courtesy of Will-O-Wisp. The threat of Will-O-Wisp can also force certain physical attackers to switch. This includes Bisharp, Garchomp, Azumarill, and many others. The last move is dedicated to healing Rotom-W as best as it can. Pain Split is useful because it allows Rotom-W to also run Leftovers, gradually recovering its HP throughout the match. It also damages the opponent if they switch in something like Chansey or Mega Venusaur and Rotom-W is at mid or low health. However, Rest has its merits as well. If Rotom-W gets hit with a status move, Rest is useful for healing it. Rest also completely heals Rotom-W, while Pain Split is dependent on the opponent's health. However, Rest is unreliable, as it can only be used once with a Chesto Berry without putting Rotom-W to sleep. Thunder Wave can be used over Will-O-Wisp, but it is usually an inferior option, as common switch-ins to Rotom-W, such as Latias, Quagsire, Chansey, and Mega Venusaur, dislike burns more than paralysis.

Set Details
========

The 44 Speed EVs allow Rotom-W to outspeed Jolly max Speed Belly Drum Azumarill. A physically defensive set is best suited to the metagame, and makes it easier for Rotom-W to counter powerful Flying-types such as Mega Pinsir and Talonflame. A specially defensive spread of 248 HP / 216 SpD / 44 Spe is also perfectly viable, allowing Rotom-W to check common specially offensive threats such as Greninja, Landorus-I, and Keldeo a bit better.

Usage Tips
========

Rotom-W has a great typing and ability that gives it many useful resistances. Because of this, it is one of the best defensive pivots in the game. However, there tends to be a lot of defensive pressure on Rotom-W, as many people expect it to check Talonflame, Mega Pinsir, Azumarill, Garchomp, Mamoswine, and other Pokemon all at once. For this reason, it's important to realize that it is simply not possible to do all these things, so the rest of the team should try and help it do its job. Rotom-W forces a lot of switches, so the option to either Volt Switch or Will-O-Wisp can be tricky. Don't be afraid to use Will-O-Wisp instead of Volt Switch, as only Pokemon like Charizard-X can safely switch into a Rotom-W that might Volt Switch or Will-O-Wisp. Sometimes people will even switch in their Ground-type in on a predicted Volt Switch, but none of these appreciate being burned.

Team Options
========

Rotom-W is one of the best users of Volt Switch in the tier, so common users of U-turn also tend to work well with it. Scizor and Landorus-T are among the best partners for Rotom-W. Scizor in particular covers Rotom-W's weaknesses well, and Mega Scizor loves to set up on common switch-ins to Rotom-W, such as Latios, Latias, and Mega Venusaur (beware of Hidden Power Fire and Sleep Powder). Pokemon weak to Mamoswine, such as Dragonite and Garchomp, really appreciate having Rotom-W, as it is nearly a perfect counter to Mamoswine, unless it carries Freeze Dry. Also, Pokemon that don't appreciate Mega Pinsir love having Rotom-W as a partner. Offensive Pokemon such as Keldeo and defensive Pokemon such as Mega Venusaur are both good options. Ferrothorn can somewhat handle Pokemon like Greninja and Manaphy, and can set up entry hazards for VoltTurn teams.

Choice Scarf
########
move 1: Volt Switch
move 2: Hydro Pump
move 3: Thunderbolt / Will-O-Wisp
move 4: Trick
ability: Levitate
item: Choice Scarf
nature: Modest / Timid
evs: 4 Def / 252 SpA / 252 Spe

Moves
========

While holding a Choice Scarf, Rotom-W takes a more offensive approach to its utility. It still makes for one of the best pivots in the game, sporting great resistances and bulk, but with much more offensive presence. Volt Switch is the main STAB move, hitting many of the Pokemon it likes to switch into such as Talonflame and Mega Pinsir. However, the main reason for using the move is the momentum that it brings, being able to give free switches to frailer members of the team, as well as allowing for a favorable match-up against whatever the opponent sends in. Hydro Pump is a powerful option to hit Ground-types and Garchomp. Thunderbolt is a more reliable STAB option that doesn't force Rotom-W to switch out and is better suited for hitting Pokemon such as Gyarados and Keldeo. However, Will-O-Wisp can also be useful for either getting a fast burn on something that might not expect it, such as Substitute Garchomp, or as a utility move after Rotom-W has removed its Choice Scarf through Trick. This can be used against more defensive switch-ins to Rotom-W such as Chansey. Hidden Power Ice or Fire can be used depending on what the team needs removed, including Landorus, Garchomp, and Scizor.

Set Details
========

The choice between Modest and Timid is entirely dependent on what the rest of the team can cover. Modest is good for guaranteeing a 2HKO on Mega Gyarados with Volt Switch and just having more power in general. Timid is really only useful to hit Jolly Mega Gyarados at +1 before it can hit back with Earthquake, although on occasion it can also pick off +1 bulky Charizard-X.

Usage Tips
========

Choice Scarf Rotom-W's utility depends on when it is best for it to Trick its Choice Scarf away. Against offensive teams, keeping the Choice Scarf is generally advisable, and Rotom-W can make for a good check to Mega Gyarados and Mega Tyranitar because it can burn both of them at +1 with Will-O-Wisp or KO weakened ones with its STAB moves. However, against defensive teams, Tricking the Choice Scarf onto a common switch-in to Rotom-W such as Chansey is a great way to cripple it for another special attacker to sweep later in the game. Volt Switch is a really useful move, and should be used as much as possible in order to get other, frailer Pokemon in for free. However, Ground-types will love switching into predicted Volt Switches, so Will-O-Wisp is often also a good move on a predicted switch. Mega Venusaur is a common answer to Rotom-W, and if the opponent has one (or any other Mega Pokemon for that matter), it is unadvised to use Trick. It is a fantastic switch-in to Rotom-W, is immune to Trick, and forces Rotom-W to switch out immediately when it could have burned it or grabbed momentum with Volt Switch.

Team Options
========

Choice Scarf Rotom-W works best on VoltTurn teams as an offensive pivot, so pairing it with other pivots works very well. Landorus-T and Scizor are among the best partners to Rotom-W for this reason. They cover each other's weaknesses well and the combo forces switches often. Because of this, reliable entry hazard setters work well with Rotom-W. Landorus-T and Skarmory fit this role nicely. Any Pokemon that appreciates Chansey being crippled will love Rotom-W's Trick support. This includes Landorus, Thundurus, and Manaphy, which can all break through Chansey more easily without its Eviolite. Keldeo in particular likes Rotom-W as a partner due to its ability to switch into Talonflame and Mega Pinsir's Quick Attack.

Other Options
########

A Choice Specs set can be used for extra power, but usually Rotom-W has better things to be doing and this role conflicts with Manaphy and Keldeo. On a similar note, a Life Orb or Expert Belt set that relies on Pain Split for recovery can be used similar to Gengar, but it runs into the same issue that Choice Specs set does; it's simply outshined as a special attacker. Dual Screens can work, as Rotom-W can also provide valuable momentum, but both Deoxys formes and Latios tend to be more universally useful aside from their crippling Psychic typing. Rotom-W can run Hidden Power Grass to hit Quagsire, but Quagsire is mostly used on stall teams, and those will usually have a better switch-in to Rotom-W than Quagsire.

Checks & Counters
########

**Bulky Grass-types**: Mega Venusaur, Amoonguss, and Ferrothorn are all decent choices to counter Rotom-W. They take very little from either Rotom-W's STAB moves or its rare coverage moves. However, with the exception of Celebi, they don't appreciate being burned by Will-O-Wisp. Ferrothorn can also wear down Rotom-W with Leech Seed and Power Whip. Leech Seed will even mitigate burn damage. Poison Heal Breloom is immune to status, so it also makes for a great switch-in to Rotom-W, and can even use it as setup fodder.

**Bulky Dragon-types**: Neither Latios nor Latias care about being hit by Hydro Pump, and usually don't care much about burns either. They can also 2HKO defensive Rotom-W with a Life Orb-boosted Draco Meteor. Bulky Charizard X doesn't mind taking Hydro Pump, Thunderbolt, or Volt Switch, and also cannot be burned or Tricked, making it an excellent switch-in to Rotom-W. Kyurem-B can switch in on any move besides Will-O-Wisp and hit Rotom-W through Levitate with Earth Power thanks to Teravolt.

**Chansey**: Chansey has huge special bulk to tank Volt Switches and Hydro Pumps and Natural Cure to heal itself of burn if it switches into a Will-O-Wisp. It can also Toxic Rotom-W to wear it down and negate its Leftovers recovery. However, Chansey is probably Rotom-W's biggest target for Trick, so Chansey must be somewhat cautious around it.

**Assault Vest Conkeldurr**: Conkeldurr takes relatively little damage from Hydro Pump and Volt Switch and actually enjoys being burned thanks to Guts. Conkeldurr can also Knock Off Rotom-W's item, which it heavily depends on for recovery and utility. With a Guts boost, Drain Punch can score a 2HKO on even physically defensive Rotom-W while recovering Conkeldurr's own health. It does have to watch out for Trick from Choice Scarf Rotom-W, however.

I think that the EV spread of 248 HP / 124 Def / 136 SAtk Modest deserves an AC mention on the first set. It scores a 2HKO on Specially Defensive Heatran at full health, even after a round of Protect, and still counters things like Talonflame well enough.

The Bold spread is so weak that it usually misses the OHKO on 88 HP Gyarados with Volt Switch. It also fails to kill Gliscor with Hydro Pump most of the time.

Definitely add this set:

- Volt Switch
- Hydro Pump
- Reflect
- Light Screen

Leftovers or Light Clay for items. Is very awesome especially for bulky Dragon Dancers like SubDD Gyarados.
 
I'm going to guess a Mixed Wall might not be viable? In case it might, this is what I've been using;

Rotom-Wash @ Leftovers
Ability: Levitate
EVs: 4 HP / 252 Def / 252 SDef
Jolly Nature (to make up for lack of Speed EVs)
- Volt Switch
- Hydro Pump
- Will-O-Wisp
- Pain Split

This set is fairly hard to bluntly OHKO, and it can take quite a few hits before having to switch out (run some calcs though, I haven't yet as I don't understand the calculator very well yet). This works very well on the team I am using, but I'm not sure how it will run on teams outside of mine. Trial and error, anyone?
 
Why the Ducklett are Specs and Scarf getting separate sets?

Also, apparently on PS defensive wash isn't as commonly used as mixed defensive / SpD...? Idk I was ruled out of a suggestion on a previous analysis b/c more wash sets are SpD apparently. I only see a SpD ACed so IDK what is up with that perhaps someone would like 2 share a mixed defensive set we could post over the AC mention that is 252 SpD only atm? (Which no one runs btw)

I personally prefer defensive but if ppl are running SpD or mixed defensive mire than the standard set it should be discussed more imo than just ACed.


Thunder Wave needs some serious AC as well as more speed investment AC to hit Defensive Gliscors and LandoT whatnot.

Team options needs VoltTurn mentioned instead of just Gene and Scizor.

Lastly, is Assault Vest viable on Rotom-W?

It's a C&C rule that Specs and Scarf sets get different sets because you play them differently. If this has changed, I'd be happy to change it though.

Defensive is definitely better atm with Mega Pinsir and Talonflame, so I agree with you there. But what do you mean no one runs 248 HP / 252 Sdef? Last gen they ran 28 SAtk EVs but that was for Gliscor, which can't be OHKOed anymore with the nerf to Hydro Pump, and I KNOW it's not going into Speed since a lot of people are actually running fewer Speed IVs to get Volt Switch initiative against other Rotom.

T wave will definitely get some good mention. It's definitely a great move to use on Rotom-W in certain situations, but idk if it's good enough for a slash. Lando-T's suggested spread is Jolly with 88, so I can't really run Speed to creep that, and idk if it's worth outrunning Defensive Gliscor with Defensive Rotom-W, because that's a decent amount of Speed. If you mean Bulky Attacker, then you already outspeed defensive Gliscor.

When this is written, VoltTurn will definitely get serious mention, but for bullet points I don't think it's super important to generally mention VoltTurn when I already have a bunch of voltturn mons listed.

I'm also curious about what people think of Assault Vest. It seems like an OO thing to me, but I'd like some input on that.

Should have this done later today.


EDIT: Also, why would I use specifically Rotom-W for Dual Screens? I feel like there are better Screens Pokemon out there, making this seem like OO material as well, but I could be convinced if there were reasons to use this over something like Deo-D, Azelf, etc. (Volt Switch is nice, but is that enough of a reason?)
 
Assault Vest is OO material at best. Rotom-W is an avid user of WoW, so passing that up is disappointing. It's also a good user of Rest and Pain Split some much needed recovery due to Rotom-W's pivot playstyle.
 
With regards to the Choice Scarf set, I think Hidden Power Ice should be removed because the nerf made it weak as hell. A 4X super effective HP Ice isn't even guaranteed to OHKO min HP Dragonite anymore, and that's after Stealth Rock damage. As a result, I think the set should look like this:

Choice Scarf
########
move 1: Volt Switch
move 2: Hydro Pump
move 3: Thunderbolt / Hidden Power Fire
move 4: Trick
ability: Levitate
item: Choice Scarf
nature: Timid / Modest
evs: 4 Def / 252 SpA / 252 Spe

Having Thunderbolt on the Choice sets is great because it gives Rotom-W a revenge-killing or late game spamming option that isn't painfully weak (Volt Switch) or inaccurate (Hydro Pump). I thought it was particularly useful last gen, and now it's even better.

Volt Switch and a plethora of resistances and immunities. Volt Switch also helps keep the momentum going while Rotom-W can use the screens itself for further harassment.

For example WoW doesnt affect Talonflame while Reflect effectively neuters its power by half. You dont necessarily have to Dual Screen like a suicide lead - you can also pick a screen then Volt Switch to the next Pokemon to use it.
 
I think the primary EV spread on the defensive set should change to 248 HP / 216 Def / 44 Spe. I've been seeing Jolly Belly Drum Azumarill on the ladder, and having the capability of burning it or attacking it with Volt Switch before it uses Play Rough can be crucial. Not to mention, it also allows Rotom-W to outpace min Speed Landorus-T before it U-Turns and max Speed Crawdaunt before it uses Knock Off. Hitting these three birds (and potentially others that I can't conjure at the moment) with one stone is more important than the negligible amount of bulk that it loses.

(Also, if that change gets approved, then the spread in AC should change to 248 HP / 80 Def / 136 SAtk / 44 Spe)

As far as Scarf goes, putting WoW in the Tbolt/HP Fire slot is for certain main slash worthy. Not only is it amazing for when you trick away your scarf, but Scarf WoW can sometimes win games itself since you burn something crucial that you normally underspeed. It is also, at least in my experience, the most common move I've seen in that last slot on ScarfTom, and I've seen IIRC only a single HP Fire used in like 250 XY matches (possibly because I don't carry Ferro ever and they have no reason to actually risk getting locked into HP Fire, but details) and only a few tbolts. It's definitely the staple move for the set.
 
I would also mention on the physically defensive spread, at least in other options but arguably on the main set 44 speed evs. While losing physical bulk sucks, and outspeeding other rotoms sucks, jolly belly drum azumarill is a problem, and with this spread you outspeed them by a point. Also, considering that everything is speed creeping rotom these days, this can be crucial to wow things like bisharp.
 
I love how bisharp is now gonna run enough speed for 44 speed rotom. l This is how speed creeps start I guess, shouldn't have given away that spread lol

Meh, it's not that big of a deal; I've personally been creeping my Bisharp past min Speed Landorus-T anyway. Plus, it's not creep for the sake of creep; it's an entirely justified increase because it helps Rotom-W beat threats against whom it would otherwise struggle with 0 Speed investment.

Is there any reason Scarf Rotom-Wash shouldn't have a Modest slash? I really can't think of anything significant that Timid beats, other than Mega Alakazam, and he doesn't show up too often anyway. Modest is able to outrun up to Timid Mega Manectric, and also beats most Pokes that have garnered one Dragon Dance, like Adamant Dragonite and (Mega) Gyarados; it loses to +1 Charizard-X, but Timid Rotom-W is slower than it as well. I've used the set all gen, and rarely have I missed the extra speed that Timid provides.
 
alexwolf, someone had asked to take this over and I was gonna give it to them, but they have full analyses themselves and are being slow ass bitches not getting them done. So I guess I'll just keep doing it myself. Sorry about the lateness.
 
On HP Ice: I wouldn't totally diss it on bulky attacker, simply because when Gliscor is Subbing and Protecting, having a 100% accurate move is awesome. It's also cool to have in case sun is up against Gliscor/Landorus-T. Hitting Noivern is also great.

Perhaps it's worth mentioning a max Special Attack spread also? The Speed is really helpful, but having the power can prove quite nice. Well, you might run the Speed you run on defensive, but w/e. A heavily invested SpA spread in AC is what I'm looking for.
 
Yeah I think that works fine by me, Jukain. I'll add that to the AC with the same speed as defensive Rotom-W uses.
