[Overview]
While Chansey was generally outclassed by Blissey in every way possible in previous generations, Eviolite now sets the two apart. Factoring in Eviolite, Chansey is one of the bulkiest Pokemon in the entire game. Sadly, even with the boost from Eviolite, it still can't stand up to Fighting type attackers who are extrememly popular in OU the popular Fighting-type attackers in OU. Because of Chansey's immense bulk, she often finds itherself on stall based teams because of it's her incredible support movepool. She's one of the few viable clerics outside of Blissey, but is much bulkier. Because of the lack of Leftovers recovery, Chansey should mainly be used on Rrain or Ssun teams, as the recoil from Hail and Sand really deteriorates Chansey's incredible bulk. Chansey's also has to rely on Seismic Toss and Toxic to deal any real damage / threaten the opponent thanks to her low attacking stats. However, play to Chansey's uses and you won't be disappointed.

<p>Chansey is a great option if your team is in need of a Cleric or Wish passer. This is mainly due to Chansey's incredible bulk, allowing her to tank nearly any special attack, and a lot of un-(remove hyphen)boosted physical attacks. This set is often compared to Blissey,(AC) who is less bulkier bulky but has the advantage of being viable on Ssand and Hhail stall teams,(RC) as well as a usable Special aAttack stat. However, on Rrain and Ssun stall teams, Chansey is the better choice thanks to her superior bulk.</p>
<p>Softboiled keeps Chansey healthy through(remove space)out the match, as without Leftovers recovery, Chansey gets worn down pretty easily by residual damage in the form of entry hazards, Sand and Hail, and switching into an attack sand, hail, and repeated attacks. Aromatherapy allows Chansey to heal her teammates and prevents Chansey from being Toxic stalled, allowing Chansey to further support the team. Aromatherapy should be used in conjunction with Softboiled. However, Chansey is also a very viable Wish passer,(RC) thanks to her incredible HP stat. Protect should be used instead of Aromatherapy if you plan to use Wish with Chansey, as it allows Chansey to heal herself and scout out the opponent. Wish allows Chansey to fully heal many Pokemon regardless of whether they invest in HP themselves thanks to Chansey's incredible HP stat. Toxic allows Chansey to wear down the opponent, and is Chansey's main way of damaging the opponent. Seismic Toss prevents Chansey from becoming complete setup bait by sweepers (especially most Substitute users trying to avoid Toxic), and allows her to reliably damage the opposition without worrying about her low offenses.</p>
[ADDITIONAL COMMENTS]
<p>The EVs have been heavily invested in both HP and physical defense, making Chansey one of the best mixed walls in the tier. Investing into physical defense also means that Alakazam and Latios have no chance in getting past Chansey with Psyshock, as well as always avoiding the 2HKO from Hydreigon's Super Power Superpower. Wish can be paired with Softboiled to reduce Chansey's dependence on receiving her own Wish, but Protect is generally better, as it allows you to scout your opponent and Toxic stall. Thunder Wave is an option to better deal with fast sweepers like such as Venusaur while also statusing Fighting-types such as Lucario and Terrakion on the switch. Chansey can also use Stealth Rock, as Chansey forces a lot of switches pretty nicely. Stealth Rock also allows you to stall out Gengar, which can often be troubling for Chansey.</p>
<p>Chansey functions well on stall and other defensive teams that appreciate Chansey's abiltiy ability to heal her teammates from status. Politoed is a great partner, as Politoed prevents Ssand and Hhail damage from wearing down Chansey, while Chansey heals Politoed of any kind of status. Latias also has great synergy with Chansey, as it takes on Fighting-type attackers such as Breloom and Keldeo, both of which can easily muscle through Chansey. Pairing Skarmory up with Chansey creates a very neat core. Unfortunately, , though this core has become less effective this generation thanks to mixed attackers such as Keldeo, Infernape, Hydreigon, and Kyurem-B. Dragonite is a very viable tank on rain teams, as with Multiscale and Dragon Tail,(RC) it can wall just about any special attacker that Blissey (do you mean chansey? this seems out of place) can't, like such as Reuniclus, Keldeo, and Jirachi. Bulky Grass-types such as Tangrowth and Ferrothorn are great partners for Chansey, mainly because they can easily switch into Physical physical attacks like and ,(AC) set up entry hazards and force switches with Sleep Powder and Leech Seed,(AC) respectively. Be careful when using both Ferrothorn and Chansey together, as they do share a Fighting-(hyphen)type weakness.(period)</p>
<p>Chansey also functions really well on Ssun stall teams. Ninetales really likes Chansey's ability to switch into rain-(hyphen)boosted attacks easily, while also keeping Ninetales free from status. Slowbro is a pretty good partner, as the two have pretty awesome synergy good synergy together. Be careful however, as using both Slowbro and Chansey can make you very weak to Breloom. Cresselia is a sturdy wall on Ssun teams and haves nice synergy with Chansey, but their roles often overlap with each other, meaning there can be some redundency redundancy. Donphan and Forretress are 2 two spinners that fit very nicely on Ssun teams. Donphan has it'(apostrophe)s water Water weakness reduced and checkcs physical attacks pretty nicely, while Forretress can tank just about any physical attacker,(RC) while also providing support in the form of entry hazards and rapid spin Rapid Spin. Sableye is the best option for a spin(remove space)blocker on Ssun teams, and shares excellent synergy with Chansey. Sableye is also one of the best counters to Reuniclus, a Pokemon that often gives Chansey a head(remove space)ache, while it can also burn physcial physical attackers, taking pressure off of Chansey.</p>
<p>Entry hazards are annoying for Blissey Chansey to switch into, so having a spinner is important. Donphan, Tentacruel,(AC) and Forretress can both Rapid Spin and appreciate Chansey's huge Wishes and her ability to come in on special attacks. They also can set up entry hazards, wearing down the opposing team. Finally, Landorus-T is one of the best switch-ins to Terrakion and Scizor, two Pokemon that often use Chansey as setup bait.</p>
<p>The main advantages of using Chansey over Blissey is are that Chansey has much better overall bulk,(RC) and can actually take quite a few psychical physical attacks. Blissey,(AC) however,(AC) has Leftovers, making it her a much better choice on Ssand and Hhail based teams, as the recoil from sand and hail really undermines Chansey's bulk. This means Chansey is a more viable on sun and rain teams respectively, meaning Ninetales and Politoed are the best partners for Chansey.</p>
[Other Options]
<p>Counter is a pretty cool option, as thanks to Chansey's incredible HP stat and low dDefense stat, cCounter will often net a KO on physical attackers. Light Screen is an okay option, as it allows other team(remove space)mates to easily tank special attacks, but this role is often better filled by Cresselia and Bronzong. Skill Swap can be used to stop Reuniclus from destroying your team. Psych Up has some value in that it can go through Substitutes and this steals defensive boosts like such as a Quiver Dance or a Calm Mind boost from a Jirachi, Reuniclus, or Celebi, but it has little use outside of that. Chansey has some gimmicky options in Sing and Charm, but Chansey she has better things to do.</p>
[Checks and Counters]
<p>The large list of Fighting-types in OU are the best way to keep Chansey in check; Terrakion, Breloom, Keldeo, Infernape, Conkeldurr, and Lucario are all Pokemon that can switch in pretty easily and force Chansey out. However, some of these must be wary of Thunder Wave on the switch. Conkeldurr is probably the most consistaent Fighting-type switch-(hyphen)in, as it doesn't care much for Toxic or Thunder Wave. Any strong physical attacker with high-powered STAB attacks or Fighting-type coverage can usually muscle past Chansey. Strong Ground- and Dragon-types like such as Garchomp, Choice Band Dragonite, and Double Dance Landorus-T can easily get past Chansey or force it out.</p>
<p>Calm Mind Reuniclus give Chansey hell thanks to Magic Guard and Recover, and can easily get past Chansey with Psyshock. Stallbreakers like such as Gliscor, Reuniclus, and Gengar easily force Chansey to switch. Gliscor is immune to status thanks to Poison Heal and can Taunt Chansey due to its higher base Speed. Reuniclus has Magic Guard and can use Chansey as setup bait. Gengar is immune to Toxic and Seismic Toss and can use Chansey's own health to its advantage via Pain Split and can also carry Taunt. Gothitelle is scary for Chansey to face, as it can easily Trick a Choice item onto Chansey, as Shadow Tag prevents switching. Once locked into a move, it can be KOed or used as setup bait the following turn.(period) (space)Magic Bounce users like such as Xatu and Espeon can easily bounce back status inducing moves and Stealth Rock. Finally, Trick users like such as Latios and Rotom-W,(RC) cripple Chansey by replacing her beloved Eviolite with a handicap.</p>
