[Overview]
 <p>Spiritomb often faces stiff competition   from   various most Rotom formes, due to various factors such as their useful   resistances, their wide and unique movepools, and their ability, Levitate.   One key thing which makes it not completely outclassed by Rotoms forms   is that it is not weak to Dark- type, meaning that Scarf Tyranitar,  one  of the most common Pokemon in the metagame, cannot Crunch or Pursuit it as easily as it can on all Rotom forms However, unlike the Rotom formes, it doesn't sport a nasty Dark-type weakness which can be exploited by physical behemoths such as Tyranitar and Scizor. Spiritomb  is a solid  and effective check to major threats such as Rotom-A,  Machamp, Azelf,  and Lucario, and access to Pressure further sets it apart, as Spiritomb can PP stall many Pokemon to death. Overall, Spiritomb has enough to set itself apart from the Rotom formes, and can function as an effective spinblocker even in the Standard environment. Spiritomb can also be used as a Rapid Spin  blocker. Spiritomb isn't as unique as the  Rotom forms. Spiritomb's ability, Pressure, enhances Spiritomb's PP  stalling capabilities.</p>

    [SET COMMENTS]
<p>Spiritomb's main use over Rotom-A is that it is not Pursuit bait, therefore and this set is tailored aims to take advantage of this that. Rest is the preferred recovery move, as it is more reliable and cures status. Sleep Talk as always pairs well with Rest; it ensures that Spiritomb isn't a sitting duck for two turns, and if it selects Will-O-Wisp, Spiritomb can actually spread burns even when asleep. Will-O-Wisp shuts down most physical attackers, and the residual damage caused allows Spiritomb to wear down many threats.  Shadow Ball is used as the STAB, mono-attacking option over Dark Pulse for two reasons: Spiritomb is too slow to abuse Dark Pulse's chance to flinch, and the occasional Special Defense drops afforded by Shadow Ball can actually force switches. Rest is Spiritomb's  most  reliable form of recovery as it can also be used to cure status   conditions. Sleep Talk works alongside Rest. The reason Shadow Ball is used over Dark Pulse is because Spiritomb is too slow to take advantage of Dark Pulse's flinch rate. Shadow Ball can also lower the opposing Pokemon's Special Defense by one stage which is quite useful for forcing switches and inflicting burns on more Pokemon. Will-O-Wisp completely cripples Physical threats.</p>
  [ADDITIONAL COMMENTS]
<p>Taunt can be used over Sleep Talk to prevent Pokemon, such as Skarmory and Forretress,  from setting up entry hazards, as they are common switch-ins to Spiritomb They are a good switch in to Spiritomb.  Hidden Power Fighting can be used over replace Will-O-Wisp as it gives   Spiritomb near-perfect coverage, but spreading residual damage and shutting down physical attackers are too good to pass up the loses the ability to inflict   residual damage each turn and also makes Spiritomb lose Physical walling capabilities. Pursuit can be used over Shadow Ball with a Careful nature to make Spiritomb a better check to Gengar, Starmie, and Azelf. Alternative EV spreads can be used too: one being 248 HP / 8 Def / 252 SpD with a Calm nature to make Spiritomb's overall defenses better balance Spiritomb's defenses after inflicting a burn, and Another EV spread than can be used is; 248 HP / 252 Def / 8 SpD with a Bold nature to make Spiritomb a better physical wall.</p>
 <p>Though Spiritomb itself functions as a team player, it will need quite some support to be effective. Tanks such as Heatran and Blissey walk all over Spiritomb, as they can freely switch into Will-O-Wisp or Shadow Ball and wear it down, or in Blissey's case, force it to use Rest by hitting it with Toxic and switch to a counter. A strong Fighting-type thus makes a good teammate, as it can OHKO both of the aforementioned tanks. Infernape in particular also takes down Pokemon such as Skarmory and Forretress, who commonly use Spiritomb as setup bait, as well as Scizor, who can hurt Spiritomb with a Choice Band U-turn, making it an excellent partner for Spiritomb. Ironically, Blissey and Skarmory too make great teammates; the former sponges powerful special attacks for Spiritomb, while the latter sets up entry hazards that wear Spiritomb's checks down and OHKOes Breloom, who can prove to be troublesome with its immunity to Will-O-Wisp once Toxic Orb activates. As for teammates, Blissey can be used to take any special move and can also function as a cleric with Aromatherapy. Hippowdon on the   other hand  . can be used to take strong   Physical moves. Pokemon that can lay down various forms of entry hazards   are also helpful, as it does damage to every Pokemon switched in and   gives Spiritomb a purpose to be used as a Rapid Spin blocker</p>
 </p>There are a few notable Pokemon that counter Spiritomb such  as  Choice Band Scizor which does a lot of damage to Spiritomb with a   U-Turn. Although Scizor can not really switch into Spiritomb as   Will-O-Wisp really hurts it. Blissey can also stop Spiritomb   in its tracks because it is not affected by Shadow Ball and Will-O-Wisp does not hurt it too much.,  as Blissey has access to Natural Cure.  It also has access to Toxic  which hurts Spitiomb. Although Rest can be  used to clear Toxic, it is  not that reliable in this scenario as it  gives the opponent a free turn  to switch out. Heatran can also  completely wall Spiritomb as it  resists Shadow Ball and gets a free  boost from Will-O-Wisp. Breloom is  also a somewhat decent counter to  Spiritomb as it becomes immune to  Will-O-Wisp after Toxic Orb activates.  Both, Forretress and Skarmory can set up entry hazards freely. (While it is certainly not wrong to talk about checks to a Pokemon in AC, please organize the paragraphs in a proper format - if you look at what I have rewritten, you will see that blended the mentions of good teammates and checks into a single paragraph)
 [Other Options]  
 <p>Sucker Punch is Spiritomb's strongest priority move, but is not   very reliable and has a low max PP but is unreliable and has low PP, making it a bad choice for a mono-attacking option; Shadow Sneak might be considered for its reliability, but it is too weak. Shadow Sneak is a weaker but more   reliable priority. Pain Split can be used to recover health as well as   inflict damage on the foe Pokemon, but RestTalk is more reliable. Taunt    can be used to stops Pokemon from setting  up entry hazards and to stop Blissey shuts down opposing walls. A Trick + Choice item set can be  used to mess up  various walls, though several other Pokemon outclass  Spiritomb in  doing this job role. Finally, Spiritomb has boosting options in Calm Mind and Nasty Plot, but is sadly too slow to set up and sweep Nasty Plot can be used to set up but  Spiritomb is too  slow to sweep. Calm Mind is a more reliable set up  move but, again,  Spiritomb is too slow to sweep.</p>
 [Checks and Counters]  
 <p>Heatran is arguably the best   check to Spiritomb. It resists both of Spiritomb's STAB's and gets a nice boost from Will-O-Wisp with Flash Fire. Shaymin is a strong special attacker that doesn't mind being burned because of its ability, Natural Cure. Crocune can set up on Spiritomb with Calm Mind. Magnezone can both hit hard and set up on Spiritomb. Blissey can also completely wall Spiritomb if Spiritomb is not carrying Taunt. Pokemon with Taunt, such as Gyarados, can prevent Spiritomb from doing anything. Pokemon that can set up entry hazards, such as Skarmory and Forretress can set up on Spiritomb. Powerful attackers, like Choice Band Dragonite and Metagross, can muscle through Spiritomb and eventually KO it. Heatran walks all over Spiritomb, as it resists both Shadow Ball and Dark Pulse while taking even Hidden Power Fighting comfortably, gets a Flash Fire boost from Will-O-Wisp, and can take it out with its powerful Fire-type attacks. Setup sweepers with Taunt, such as Gyarados, do a great job of checking Spiritomb as well, as they can shut it down completely and proceed to set up on it. Blissey doesn't mind taking a Will-O-Wisp thanks to Natural Cure, and laughs at Spiritomb's other attacks as well, though it can't do anything back either. Choice Band users such as Metagross, Dragonite, and Scizor can muscle through weakened Spiritomb with their sheer power, though they need to be careful when switching in, as Will-O-Wisp will shut them down. Finally, if Spiritomb lacks Taunt, Pokemon such as Skarmory and Forretress can freely switch in and use it as setup bait.</p>
