~ Seismic Toss / Flamethrower
~ Toxic
24 HP / 252 Def / 232 SpD

With her massive base 255 HP and 135 Special Defense stats, Blissey is the best special wall in the game. She can freely switch into any special move, heal off the damage, and then either stall the opponent out with Toxic or slowly whittle it down with an attacking move.

Wish allows Blissey to heal both herself and her teammates, as the healing is delayed by one turn. By passing Wishes around your team, you prolong its ability to fight and make it harder for your opponent to take it down. Protect can be used to scout out your opponent's move. For example, should a Choice Band Tyranitar use Pursuit, Blissey can stay in on it and stall it out with Toxic. If it were to use Crunch, then Blissey can easily switch out to a Pokemon that resists it. Seismic Toss is the main attack as it can hit every type of Pokemon except Ghost-types for a constant 100 damage. Flamethrower may be used as an alternate attack in order to hit Steel-type switch-ins such as Scizor and Lucario, along with Ghost-type Pokemon, though it leaves Blissey walled by Heatran. Ice Beam can be used to prevent Salamence from setting up a Dragon Dance. Toxic rounds out the set, allowing Blissey to stall out any potential attackers with a rotation between Wish and Protect. Heal Bell can be used to heal your Pokemons' status conditions, although it leaves Blissey with only an attacking move to cause damage and prevents her from stalling out the opponent with Toxic. The reason Aromatherapy cannot be used is that Aromatherapy is an egg move and Wish is an event move. Thunder Wave can also be used to cripple the opponent's Pokemon.

Protect is the main option for the second slot, as it allows Blissey to gain an extra turn of Leftovers recovery and scout the opponent's move. However, Softboiled may be used as it has several advantages over Protect. If Blissey has both Softboiled and Wish, she can use Softboiled to heal herself and Wish to heal her teammates. The increased healing capabilities provided by the two moves can be useful in a stall war. Another advantage of having Softboiled is that with only Wish, Blissey has to stay in and Protect in order to heal herself, which may allow an opposing physical attacker the opportunity to set up. Softboiled has one final benefit: it can heal Blissey before she gets taken down by hail or sandstorm damage.

The EVs are designed to maximize Blissey's defenses and to reach a Leftovers number plus one. Due to Blissey's massive HP stat, investing in her individual defensive stats would increase her overall bulk more than investing in her HP stat. Should you choose to use Flamethrower on Blissey, you may move 80 Special Attack EVs from HP and Special Defense to have a spread of 252 Def / 80 SpA / 176 SpD. 176 Special Defense EVs allow Blissey to avoid being 2HKOed by Choice Specs Lucario's Aura Sphere and Choice Specs Gengar's Focus Blast.

Blissey is the perfect choice for teams that are weak against special attackers such as Choice Specs Jolteon, Substitute Petaya Empoleon, and Life Orb Starmie. Even though Blissey's Special Defense is outstanding, she easily falls prey to physical attacks. A Pokemon must be utilized in order to handle the various physical blows from the likes of Choice Band Tyranitar, Machamp, and Swords Dance Lucario. One of the best defensive combinations is the well-known "SkarmBliss" combination, which takes advantage of Skarmory's physical bulk. Skarmory can come in on many physical attacks and set up Spikes or phaze away the opponent with Whirlwind. Forretress enjoys having Wishes passed to it, as it can now come back in several times to set up entry hazards or Rapid Spin away any entry hazards on its side. With Spikes on the field, the opponent will take more damage trying to get a physical attacker in to combat Blissey. Gliscor also fulfills the physical wall role well, as its typing provides a resistance to Fighting-type moves and can prevent the opposing Pokemon from healing with Taunt. Hippowdon is an incredible physical tank and can set up Stealth Rock and use Roar to shuffle the opposing team around. Defensive Gyarados can also switch in and use Roar or Taunt on the opposing Pokemon. In the meantime, Blissey can handle the various Flamethrowers, Surfs, Ice Beams, and Thunderbolts heading towards the aforementioned Pokemon.

Despite the synergy between Blissey and the aforementioned physical walls, there are still several Pokemon that can set up on Blissey and become a menace to any of her teammates. Tyranitar, Metagross, Lucario, Salamence, Gyarados, and other Pokemon can easily boost their stats and threaten a sweep. Fortunately, many different types of Pokemon can handle these threats. Non-Babiri Berry Tyranitar and Dragon Dance Salamence can be revenge killed by Choice Band Scizor. Gliscor can handle Lucario and Tyranitar with some luck, as Tyranitar will have only a 64% chance of 2HKOing Gliscor with Crunch while Gliscor 2HKOes it back with Earthquake. A Rotom appliance (notably Rotom-H) can handle Metagross, Lucario, and Gyarados. A bulky Water-type Pokemon such as Vaporeon or Suicune can handle Gyarados and Salamence with Hidden Power Electric and Ice Beam respectively. Should Salamence not carry Fire Blast or Flamethrower, Skarmory can switch in and phaze it away with Whirlwind. Almost all Salamence have Fire Blast, so Hippowdon is a solid initial switch-in either way.

24 HP / 252 Def / 232 SpD

The idea behind this set is fairly straightforward: switch in on a special attacker, heal your team of any status ailments, and respond to the opponent's next move appropriately.

Aromatherapy is the main move on this set, cleansing your team of any status problems that it may have. With it, your team no longer has to worry about having a dedicated status absorber, as Blissey can easily use Aromatherapy to heal off any problems. Softboiled provides an instant recovery move for Blissey, while either attack is acceptable. Thunder Wave cripples Gengar and Rotom-A who switch in thinking they can take a Seismic Toss, while Toxic is there for stalling capabilities. It should be noted that without Protect, the ability to stall is more difficult as Blissey can no longer alternate between Wish and Protect and instead must rely on constantly using Softboiled.

This set is incredibly useful on a stall team, as it allows Blissey to rid the team of any potential status ailments. She can also be used on an offensive team to get rid of any harmful status conditions your sweepers may be afflicted with. However, a Blissey using this set can also be a liability, as Aromatherapy allows a check to easily come in and immediately threaten Blissey. Physical sweepers such as Swords Dance Scizor and Lucario can scare Blissey out, while Substitute Gengar and Rotom-A are immune to Seismic Toss and status if using Substitute. You can choose to either attack or attempt to status the opposing Pokemon first before using Aromatherapy.

The EVs are exactly the same as the previous set. If you are using Flamethrower, you may use a 252 Def / 40 SpA / 216 SpD EV spread instead. 216 Special Defense EVs provide the maximum jump point for Blissey and ensures that Blissey will never be 2HKOed by a Flash Fire boosted Fire Blast from Choice Specs Heatran. The remaining EVs can go into Special Attack.

As mentioned above and in the previous set, Blissey needs team support in order to deal with physical attackers and Pokemon that can set up in front of Blissey. Gliscor, Rotom-H, Scizor, and bulky Water-type Pokemon can handle the problematic Pokemon. However, additional support is needed for Gengar and Rotom-A. Calm Minders like Jirachi and Suicune can help check these two Pokemon, while Spiritomb can handle both of them easily. Swampert can also switch in and stop Rotom-A from boosting its Special Attack with Charge Beam. It can then Roar Rotom-A out to remove its Special Attack boosts. Additionally, physically defensive Pokemon can take the physical attacks aimed towards Blissey. Gliscor, Skarmory, Hippowdon, and Gyarados are all viable physical walls to fulfill this job.

~ Seismic Toss
~ Ice Beam / Flamethrower
~ Thunder Wave / Toxic
~ Softboiled
152 HP / 252 Def / 104 SpA

This is a set that you can use on Blissey if you are not satisfied with only one attacking option. It also allows Blissey to keep spreading status around as well. With the variety of attacks, opposing Pokemon will find it harder to set up on Blissey. Blissey will still be able to wall special attackers fairly well, though not to the extent of the other sets.

Seismic Toss is chosen for the consistency it provides. Ice Beam hits opposing Salamence and Latias, as well as Ground-type Pokemon that are immune to Thunder Wave. Meanwhile, Flamethrower is best used alongside Toxic, as it hits Steel-type Pokemon that are immune to poison. However, you may choose to use Ice Beam with Toxic and Flamethrower with Thunder Wave if that's what your team requires. Stealth Rock can be used on this set over the second or third move because Blissey will have many free turns to set it up. However, there are several other attacking options that may be used. Thunderbolt can help hit bulky Water-type Pokemon along with Skarmory, while Hidden Power Ground hits both Heatran and Tyranitar in one move. Grass Knot is the strongest move that Blissey can use against Tyranitar aside from Focus Blast (which is extremely risky) and also hits Swampert and Hippowdon. Feel free to experiment with the moves to fit the situation.

The EVs are primarily transferred from the ADV era, where Blissey didn't need any Special Defense EVs in order to wall attacks. However, a 252 Def / 80 SpA / 176 SpD EV spread with a Calm nature can be used also if you want Blissey to take special hits better.

Even with an additional attack, this set still plays similarly to other Blissey sets. Therefore, Blissey will need similar Pokemon as teammates. Once again, physical walls are good partners for Blissey, as they can take the physical based attacks aimed at her. Gliscor, Skarmory, and Hippowdon are all great physical walls with their own forms of instant recovery, while Cresselia serves as a great mixed wall. With Seismic Toss and Ice Beam, Steel-types such as Scizor and Metagross can easily come in and set up on Blissey. Rotom-H serves as a great counter to these two Pokemon. If you are using Flamethrower, then Heatran can come in and either poison Blissey with Toxic or use Explosion. Tyranitar can also come in and Dragon Dance in front of Blissey, fearing only a predicted Thunder Wave. RestTalk Gyarados and Crocune can handle Heatran, while Swampert, Hippowdon, and Machamp can all handle Tyranitar.

4 HP / 252 Def / 252 SpD

Even with incredible walls such as Giratina and Lugia in the Uber tier, Blissey is still the number one special wall to use. Blissey is the only Pokémon in Ubers that can wall such a wide variety of special threats, such as Latias, Latios (as long as it lacks Refresh or Safeguard), Palkia, Dialga (provided they aren’t mixed), and Calm Mind Lugia. As far as attacking options go, Seismic Toss is generally the most reliable as it will do a decent amount of damage to Pokémon like Kyogre and Latias who would otherwise laugh at Ice Beam. Seismic Toss also allows Blissey to have a better chance of beating Mewtwo that have Calm Mind and Taunt, which Ice Beam can not accomplish. Ice Beam is still a good option though, as three common Blissey switch-ins (Groudon, Garchomp, and Rayquaza) are hit super effectively by it. With 84 SpA EVs, Garchomp takes a massive 76.19% - 90.76% from Ice Beam when it switches in, while a 0 HP / 4 SpD Rayquaza will be OHKOed after switching into Stealth Rock. In emergencies, you can leave Blissey in on Rayquaza, because the opponent may attempt to set up a Dragon Dance or Swords Dance. When using Seismic Toss, use the EV spread 4 HP / 252 Def / 252 SpD, as there is no reason to invest in Special Attack when using it. Toxic complements this set well, as the combination of Protect and Wish can very easily stall Pokémon to death. Toxic is a good choice to use if you predict the opponent is going to switch, as several threats to Blissey (Kyogre, Darkrai, and Giratina-O) become much easier to handle when badly poisoned. Thunder Wave can be used over Toxic, but make sure you use it only with Seismic Toss. This is because without Seismic Toss or Toxic, Latias can set up Calm Minds with no problem and eventually KO Blissey. Although not recommended due to moveslot competition, Heal Bell can be used over Protect if your team needs both a status releaver and a user of Wish.

Blissey is one of the few viable Wish passers in the Uber tier, thus many good teammates for Blissey are simply Pokémon that greatly appreciate Wish. A perfect example of this is Choice Specs Kyogre. While Choice Specs Kyogre is an insanely powerful wall breaker, Water Spout's power will unfortunately decrease as Kyogre's HP diminishes. With Blissey's Wish, Kyogre can have a chance to have an extremely powerful Water Spout again. In a similar manner, Choice Scarf Kyogre will also love Wish. Wobbuffet is another Pokémon that greatly benefits from Wish support. It, while being bulky, will usually only be able to revenge kill one Pokémon per match. With Blissey's Wish, Wobbuffet will be able to stay in battle for a much longer period of time, thus making it much more difficult for the opponent to handle. Another Pokemon that benefits from Blissey's Wish is Forretress. This will allow Forretress to take more powerful hits from the likes of Garchomp, allowing it to have more time to set up Spikes and Toxic Spikes. Finally, a defensive support Groudon will have a much easier time dealing with Lucario and Rayquaza thanks to Blissey's Wish support; as well as support Dialga having an easier time dealing with Palkia and Kyogre.

While Blissey may still be the queen of special walling in Ubers, some of the special attackers of Ubers are so powerful that they can break through her. A good example of this is Kyogre, which has several sets that can make Blissey run for cover. Choice Specs Kyogre is so absurdly powerful that it can 2HKO Blissey with Water Spout, as long as it has at least 80% of its health. Kyogre can also use 252 HP EVs to make 101 HP Substitutes, which means that it can set up Calm Mind while Blissey is forced to use Seismic Toss twice to break the Substitutes. After three Calm Minds, a Modest Kyogre will always 2HKO Blissey with Surf, even when accounting for Leftovers recovery. Finally, Kyogre may carry the combination of Sleep Talk and Rest to either set up Calm Mind on Blissey or to outstall her. To solve the problems Blissey has with Kyogre, Latias should always be considered. Latias can switch into Choice Specs Kyogre's Water Spout, and use Thunder to weaken its power by reducing Kyogre's HP. Latias can use Calm Mind as the other Kyogre variants attempt to set up, and will usually beat it. The combination of Latias and Blissey will wall every single Kyogre set, making Latias an excellent teammate for Wish Blissey. Palkia is another good option if you only need a Pokémon to beat Choice Specs Kyogre. Something to note is that once Kyogre has switched into Stealth Rock twice, it will no longer be able to 2HKO Blissey with a Choice Specs Water Spout, thus Blissey will be able to wall it with ease as long as there are no critical hits. Manaphy can also cause serious issues for Blissey when it’s raining. It will be immune to status and can set up Tail Glow or Rest off the damage it has taken and wake up immediately afterwards, thanks to its ability, Hydration. After two Tail Glows and Life Orb, Manaphy will always 2HKO Blissey with Surf. To beat Manaphy, Latias once again makes an excellent teammate, as it OHKOes it with Thunder after Stealth Rock and will win a Calm Mind war if Manaphy attempts that.

Nasty Plot Darkrai can cause some serious problems for Blissey. After one use of Nasty Plot, Darkrai will 2HKO Blissey with Focus Blast. To make matters even worse, Darkrai can carry Substitute to block Thunder Wave and Toxic. It can also put Blissey to sleep with Dark Void, not only giving it the opportunity to set up, but also dealing damage with its ability, Bad Dreams. Generally, the best way to deal with Darkrai is to predict a Dark Void and send in a sleep absorber (usually carrying Sleep Talk, but this is not required). Then, switch to a Pokémon that can revenge kill Darkrai (such as Life Orb Mewtwo, Choice Scarf Palkia, Choice Specs Shaymin-S, etc.). Something to note is if a Choice Scarf Darkrai switches into Blissey, it is likely that it is carrying Trick, thus it is best to switch to a Choice Scarf user of your own or a Pokémon that does not mind being Tricked with a Choice Scarf.

Mewtwo can also pose a problem for Blissey, due to Taunt and Substitute. Mewtwo can make 101 HP Substitutes and use Calm Mind to beat Blissey in a similar way Kyogre can. It also has the option of using Taunt and Recover to PP stall Blissey, thanks to Pressure. In a similar manner, Mew can Taunt Blissey and use the time to set up and Baton Pass to a powerful Pokémon such as Groudon. To stop Substitute Mewtwo and Baton Pass Mew, Scizor makes an excellent choice. Mewtwo can be hit hard by Pursuit even if it stays in, while Mew will get its Reflect and Light Screen broken by Brick Break and be OHKOed by U-turn. Choice Specs Kyogre also works well, as it can switch into a defensive Mewtwo with ease and threaten to OHKO with Water Spout, while Mew will take massive damage.

Another problem for Blissey is Giratina as it can easily outstall Blissey due to its Pressure ability and Ghost-typing. Giratina can also use a combination of Sleep Talk, Rest, and Calm Mind to set up on Blissey. Although it’s very rare, Latias and Latios can beat Blissey in a similar manner with Calm Mind, Recover, and either Refresh or Safeguard. Generally, the best answer to Giratina is Bulk Up Dialga. Dialga can easily set up Bulk Up as Giratina uses Will-O-Wisp and then use Rest to restore its health. After three uses of Bulk Up, Dialga will always OHKO Giratina with Outrage. For Calm Mind Giratina, Tyranitar can switch in and cause a serious amount of damage with a Choice Banded Crunch. For Latias and Latios, Tyranitar, Scizor, and Metagross can penetrate them with Pursuit or their powerful STAB attacks.

If Giratina-O switches in on any move but Thunder Wave or Toxic, it can pose a serious threat to not only Blissey, but also to the rest of the team. Blissey will have a difficult time breaking Giratina-O's Substitutes with Ice Beam. If it uses Calm Mind, Blissey will no longer be able to break Giratina-O's Substitute, meaning that Giratina-O can continue to set up Calm Mind. After four uses of Calm Mind, Giratina-O is able to 2HKO Blissey with Dragon Pulse, and then threaten to sweep the rest of your team. To solve this issue, it is advisable to use a Careful Forretress with Light Screen and Payback. Forretress can switch into Giratina-O, use Light Screen to minimize the damage it takes, and then 4HKO Giratina-O with Payback. It is also a huge help to Blissey, due to Toxic Spikes. When Forretress sets up two layers of Toxic Spikes, several big threats to Blissey, such as Darkrai, Choice Specs Kyogre, and Substitute Mewtwo, will become much easier to handle due to the constant damage from poison. If Forretress does not fit on your team, it is best to use Tyranitar, whose combination of Crunch and Sand Stream will make Giratina-O's life short.

If Shaymin-S is using a Modest nature and Choice Specs, it can 2HKO Blissey with Seed Flare if it gets a Special Defense drop. Choice Scarf Dialga, Choice Scarf Heatran, Choice Scarf Jirachi, and Choice Scarf Metagross are capable of switching into a Choice Specs Seed Flare, and can OHKO Shaymin-S with Draco Meteor (Dialga), Fire Blast (Dialga and Heatran), or Ice Punch (Jirachi and Metagross). Be warned, Choice Scarf Jirachi and Choice Scarf Metagross will still take a siginifcant amount of damage from repeated switch-ins to Seed Flare, despite their resistance. Skarmory can take a Seed Flare due to its 4x resistance, and Whirlwind Shaymin-S away. Choice Band Scizor can also switch into Seed Flare, and threaten to 2HKO it with Bullet Punch. Latias and Lugia can survive two Seed Flares (although it will do a severe amount of damage to both if it gets a Special Defense drop), and threaten to OHKO Shaymin-S with Dragon Pulse and Ice Beam respectively after taking Stealth Rock damage.

While Leftovers is generally the preferred option, Shed Shell is a very viable alternative in Ubers because of Wobbuffet. Wobbuffet can switch into Blissey, trap it, and use a combination of Tickle and Encore several times. After Wobbuffet is done Tickling Blissey, the opponent can switch to Scizor or Tyranitar to eliminate Blissey with Pursuit. Due to Wobbuffet's ability, Shadow Tag, this is completely unavoidable without the use of Shed Shell. Blissey can also become set up bait for Wobbuffet, which is very undesirable with the powerful sweepers roaming around in the Uber tier.

Moveset EVs
~ Softboiled
~ Seismic Toss / Ice Beam
~ Toxic / Thunder Wave
~ Ice Beam / Aromatherapy
252 Def / 84 SpA / 172 SpD

This set is very similar to Wish Blissey, but it forgoes the supportive nature of Wish and Protect in exchange for Softboiled, which frees up an extra moveslot for Blissey. The best two moves for this moveslot are Ice Beam or Aromatherapy. With the EV spread above, Blissey's Ice Beam is able to OHKO Rayquaza with 4 Special Defense EVs 100% of the time after it takes Stealth Rock damage, thus making Blissey an effective Rayquaza lure.

Aromatherapy can be especially useful in Ubers for a number of reasons. Thunder is one of the most common moves used in the Uber tier, and with it comes a 30% chance of paralysis which can ruin the many sweepers of the tier. Darkrai is also a huge threat in Ubers, and can often cripple a Pokémon for the entire match with Dark Void due to the fast paced nature of Ubers. With that being said, many of Aromatherapy Blissey's best teammates are powerful or game changing Pokémon that are very vulnerable to status effects. A good example of this is Wobbuffet. When Wobbuffet is using Encore to either destroy a wall with the Tickle + Pursuit user combination, or just trying to set up a sweeper, Wobbuffet will often get hit by Toxic or Will-O-Wisp, cutting down its survivability. Blissey's Aromatherapy can remove Wobbuffet's status affliction, allowing Wobbuffet to do its job of removing Choice Scarf Pokémon more easily. Another good teammate is a Quiet mixed Dialga. While mixed Dialga will easily destroy Giratina with Draco Meteor, Giratina can use Will-O-Wisp to destroy Dialga's chances of breaking through Latias and Blissey. With your own Blissey's Aromatherapy, Dialga can once again be a powerful wall breaker. Finally, Lugia works very well with this particular Blissey. This is because Lugia, when trying to beat Groudon, can often be hit by Thunder Wave and Toxic, meaning it will be unable to harm the team with the combination of Whirlwind and entry hazards for much longer. Thanks to Blissey's Aromatherapy, Lugia can once again wear down teams with Whirlwind. Generally, Aromatherapy Blissey does very well with sweepers that can be crippled by Paralysis and Burn.

This set will generally have the same issues Wish Blissey has, so refer to Wish Blissey's team options for how to beat its special attacking enemies.

Ubers Calm Mind

Moveset EVs
~ Calm Mind
~ Ice Beam
~ Thunder
~ Softboiled
252 Def / 84 SpA / 172 SpD

With a few adjustments, Calm Mind Blissey can work very well in Ubers. Once again, Blissey should use a Calm Nature with an EV spread of 252 Def / 84 SpA / 172 SpD to OHKO Rayquaza with Ice Beam after it switches into Stealth Rock. Thunder should also be used in place of Thunderbolt, mainly due to its use with the rain support Kyogre gives Blissey, making Thunder 100% accurate, and a powerful attack that has a 30% chance to induce paralysis. While Serene Grace is most certainly a worthy option (especially with a 60% chance of paralysis with Thunder), Natural Cure is usually preferred because without it, Blissey will be crippled by Toxic.

One of the biggest selling points of Calm Mind Blissey in Ubers is the ability to beat certain threats that Wish Blissey and Aromatherapy Blissey would normally lose to. For example, Calm Mind Blissey can boost against Giratina-O and eventually destroy it with Ice Beam. Another good example is Choice Specs Kyogre. If Kyogre switches on Blissey as it uses Calm Mind, Kyogre will be 2HKOed by Thunder after Stealth Rock. Thus, Kyogre will no longer pose a threat to Blissey with its weakened Water Spout. It will also beat Calm Mind and Substitute Kyogre by Calm Minding along with it, while Blissey being able to easily recover its health and beat Kyogre with Thunder. Giratina that lack Calm Mind are also beaten by Calm Mind Blissey, because Giratina's Dragon Claw will only do 31% max to Blissey (even Outrage only does 46% maximum). However, Blissey requires three Calm Minds to 2HKO a 248 HP / 8 SpD Giratina. If Manaphy switches in on Blissey it will also lose. This is because Blissey can use Calm Mind as Manaphy sets up Tail Glow. Even a +6 Manaphy will be unable to 2HKO Blissey with Surf in the rain after Blissey has used Calm Mind three times. Meanwhile, a +3 Blissey will be able to OHKO Manaphy with Thunder. Substitute Mewtwo with Calm Mind and Latias or Latios with Calm Mind and Refresh or Safeguard will lose to Blissey in a way like Calm Mind Kyogre.

Calm Mind Blissey will struggle with Calm Mind Kyogre and Calm Mind Giratina that have Rest and Sleep Talk, as they will be able to outstall Blissey unless it gets a critical hit. Additionally, any Pokémon that has Roar or Whirlwind along with Calm Mind can phaze Blissey away, and threaten to sweep. The best example of this is Calm Mind Lugia. To foil Kyogre's plans, once again Latias is easily the best answer, as Kyogre will do little damage to Latias with Surf, while Latias has no problems setting up Calm Mind on it. For Calm Mind Giratina, Bulk Up Dialga can switch in. While a +4 Dragon Pulse will do massive damage to Dialga, a +3 Outrage will always OHKO Giratina. Choice Band Dialga can also beat it with Outrage. Choice Band Tyranitar will also receive minimal damage thanks to the Special Defense boost Sandstream grants it, and can inflict large amounts of damage to Giratina with a Choice Banded Crunch. Tyranitar can also Taunt both Lugia and Giratina and threaten to set up a sweep with Dragon Dance. Support Dialga can also take care of Calm Mind Lugia by crippling it with Toxic. Finally, Mewtwo that have Taunt and Calm Mind can easily set up on Blissey. Metagross and Scizor can usually deal with this variant of Mewtwo, as they often lack Fire attacks.

Psych Up can go over Calm Mind and has several pros and cons. With Psych Up, Blissey can copy stat boosts from Kyogre or Latias that have gotten a large amount of Calm Minds and stop their sweep. However, this comes at the cost of losing to Choice Specs Kyogre, Giratina, and Tail Glow Manaphy in the rain. To beat Kyogre and Manaphy, Latias is once again the best choice, while Bulk Up Dialga or Choice Specs Dialga will annihilate Giratina. As always, Shed Shell is a very viable option as it allows Blissey to escape death by Wobbuffet.

Team Options

OU

Blissey is the best special wall in the game. However, her physical Defense is lacking. Therefore, it is highly recommended that you have a Pokemon on your team that can take repeated physical hits. Skarmory pairs well with Blissey, forming the infamous "SkarmBliss" combination, where Skarmory takes the physically-based moves aimed at Blissey and Blissey takes the special-based moves aimed at Skarmory. Skarmory can also set up Spikes in order to prevent the number of times the opponent's Pokemon can switch in. Gliscor is another good choice for a physical wall, as it can check Swords Dance Lucario and can also use Taunt to prevent the opponent from healing away any potential damage taken. Gliscor also has a resistance to Fighting-type moves instead of a neutrality to them like Skarmory. Hippowdon is another viable wall, as it can rack up more residual damage with Roar and set up Stealth Rock. Gyarados can either Taunt opposing Pokemon or use Rest and Sleep Talk to prolong its life. Intimidate also helps Gyarados sponge the inevitable physical attacks as it switches in.

Despite all of the combinations, Blissey can still be easily set up upon. Scizor, Metagross, Lucario, Tyranitar, Gyarados, Salamence, Infernape, Gengar, Rotom-A, and many more Pokemon can all set up on Blissey. Fortunately, a wide variety of Pokemon can handle these threats. Scizor, Metagross, Gyarados, and Lucario are all handled by Rotom-A. Rotom-H is the most viable, as Overheat allows it to smash Scizor, Metagross, and Lucario. Choice Band Scizor can handle non-Babiri Berry Tyranitar, a weakened Dragon Dance Salamence, and non-Substitute or Protect Gengar with Bullet Punch (or Pursuit in the case of Gengar). A bulky Water-type Pokemon can also switch in to handle some of these threats. Vaporeon and Suicune handle Infernape, Gyarados, and Salamence provided they are at a high HP upon switching in, while Swampert can prevent Rotom-A from obtaining any more Special Attack boosts from Charge Beam.

Ubers

When using Blissey in Ubers, Forretress should always be considered for the purpose of laying down Toxic Spikes and Spikes. This is because Blissey will force a lot of switches on the opponent’s side due to many Uber Pokémon focusing on special attacks. Toxic Spikes in particular are a huge help to Blissey, as they will wear down Pokémon such as Choice Specs Kyogre, Mewtwo, Garchomp, and Groudon; all of which are problems for Blissey. Stealth Rock can also be useful for the same reasons. Although Blissey can use Stealth Rock herself, it is better to have other Pokemon do this for her. Dialga and Groudon are good examples of this. Deoxys-S and Deoxys-D can also use Spikes that Blissey can benefit from. This can be useful because once Spikes and Stealth Rock are layed, Choice Specs Kyogre can no longer break through Blissey.

Many teams rely on revenge killing their opponents with powerful special attacks in order to deal with certain threats. For example, many teams count on Choice Scarf Palkia to OHKO Darkrai with Draco Meteor. Blissey can work very well with Darkrai in this case. She can easily switch into the incoming Draco Meteor and use the time to either status the next switch-in or switch to another Pokémon that takes advantage of an incoming physical attacker . In a similar manner, Blissey can also partner well with Garchomp, Rayquaza, and Groudon. Many teams use Lugia to stop all three, and Blissey has no problems with switching into Lugia’s Ice Beam. Blissey can then threaten to cripple it or the next switch-in with Toxic.

Much like OU, Blissey’s biggest problem in Ubers are powerful physical attackers that can take advantage of Blissey’s meager base 10 Defense. Garchomp can switch into Blissey while it is using anything but Toxic and Ice Beam, and threaten to do a huge amount of damage with STAB Outrage. Groudon can also switch in and threaten to do huge amounts of damage with STAB Earthquake. Rayquaza, although loathing Thunder Wave and being KOed by Ice Beam, can threaten to either OHKO Blissey with Outrage or set up a sweep. Although most commonly seen as a special attacker, Dialga may use Bulk Up which causes some serious problems for Blissey. Finally, several threats in OU, such as Scizor, Tyranitar, Metagross, and Lucario, are still big issues for Blissey in Ubers. Lugia can make an excellent teammate because of these threats. It can handle Rayquaza, Bulk Up Dialga, Groudon, Metagross, Lucario, and Scizor thanks to its wonderful Defense stat and can OHKO Rayquaza with Ice Beam after it switches into Stealth Rock. Lugia can use Reflect and Whirlwind to keep the other physical attackers at bay. Reflect itself can aid Blissey in taking U-turn from Scizor and will let her survive Pursuit from Pokémon such as Metagross and Tyranitar as well. Be warned though, while Bold Lugia can handle Choice Scarf Garchomp, it will have trouble dealing with Swords Dance Garchomp. If Swords Dance Garchomp is particularly troubling for your team, make sure Lugia is Timid with an EV spread of 252 HP / 66 Def / 192 Spe. This allows Lugia to outspeed a Jolly Garchomp, and set up Reflect before Garchomp can destroy Lugia with a boosted Stone Edge. Groudon is another great teammate for Blissey. Groudon, with its massive Attack and Defense stats, will easily scare off Tyranitar and Metagross with STAB Earthquake. When using an Impish Groudon, Lucario will fail to OHKO it with a +2 Close Combat, while Groudon will easily OHKO back with Earthquake. Finally, Groudon can deal massive damage to Bulk Up Dialga with STAB, super effective Earthquake. Giratina is another good choice as a teammate for Blissey. Giratina can use Will-O-Wisp on Metagross, Scizor, Groudon and Lucario, ruining their ability to sweep. Much like OU, Skarmory is still an excellent partner for Blissey in Ubers. Skarmory can switch into Garchomp, Scizor, Metagross, and Groudon that lack Fire Punch, and set up Spikes. If any of these foes dare to set up, Skarmory can easily use Whirlwind to make their efforts futile. If one would prefer a more offensive way to deal with these threats, Choice Scarf Shaymin-S can outpace Groudon even after it uses Rock Polish and OHKO it with Seed Flare. Choice Scarf Dialga can revenge kill Swords Dance Rayquaza, Lucario, and Choice Band Garchomp, while Choice Scarf Palkia can revenge kill Dragon Dance Rayquaza. Choice Scarf Jirachi is able to destroy and outrun any Rayquaza due to its 100 base Speed, and can use its Steel-typing to switch in and OHKO Rayquaza with Ice Punch. Choice Scarf Jirachi can also cripple Wobbuffet switch-ins by Tricking them with a Choice Scarf.

Blissey despises users of Leech Seed. The three main users of Leech Seed to watch out for in Ubers are Ludicolo, Jumpluff, and Shaymin-S. Ludicolo can use its Rain Dish ability to restore even more health, Jumpluff can use its Speed to Encore Blissey’s non-attacking moves, and Shaymin-S can threaten to flinch Blissey with Air Slash. The best way to deal with Jumpluff is to use Scizor. Scizor can use U-turn after Jumpluff uses Leech Seed, and then you can switch to Lugia to Ice Beam it. Ludicolo, if lacking Surf, can be set up on by Forretress. You can then use a phazer such as Lugia or Skarmory to force a switch, meaning Ludicolo will be crippled by Toxic Spikes on the next switch-in. Finally, Shaymin-S should be dealt with by Choice Scarf Dialga, who sports a 4x resistance to Seed Flare, and can OHKO Shaymin-S with Draco Meteor. Choice Scarf Jirachi is also capable of revenge killing Shaymin-S with Ice Punch. Lugia and Skarmory can also Whirlwind Shaymin-S away, forcing it to take more damage from Stealth Rock on the next switch-in.

In the Uber tier, many special attackers such as Mewtwo, Darkrai, Palkia, Dialga, and Giratina-O will use mixed sets with the main purpose of beating Blissey. A good strategy against this is to use Protect while these Pokémon attempt to beat Blissey, which can reveal whether they are mixed or not. Mixed Darkrai will be effectively handled by Forretress and Scizor if it lacks Hidden Power Fire, while Darkrai that lack Thunder will be destroyed by Kyogre. Palkia can be much more difficult to handle, as it has no true counter. It not only has the capability of using normal mixed sets, but it can also use the combination of Substitute and Focus Punch to destroy Blissey. If Palkia attempts to use Aqua Tail on Blissey, you can switch Latias into it, and threaten to OHKO Palkia with Dragon Pulse. Be warned though, as Palkia may also carry Outrage with the purpose of destroying Latias switch-ins. Garchomp, although unable to switch into Palkia, is able to revenge kill it. A Choice Scarf Metagross can switch into Palkia’s physical assaults and then use Explosion on it. Mixed Dialga can also pose a threat for Blissey, because either Outrage or Brick Break can 2HKO it. Groudon can switch into Dialga’s Outrage or Brick Break, and threaten devastation with Earthquake. Mixed Giratina-O is generally beaten by Scizor if it's raining, as then Hidden Power Fire will not OHKO Scizor, while Scizor can wear down Giratina-O with Pursuit and Roost. Mewtwo can be particularly difficult to beat if it is running a mixed set, because Mewtwo can use Selfdestruct to destroy one of your Pokémon. Usually, the best option against Mewtwo beyond Toxic Spikes is to use a faster Pokémon (such as Choice Scarf Darkrai, Choice Scarf Palkia, etc.) to kill Mewtwo before it kills you.

Other Options

OU

Besides the recommended Seismic Toss and Flamethrower, Blissey can also use Ice Beam and Thunderbolt. Ice Beam scares away Dragon-type Pokemon and Gliscor while Thunderbolt handles Gyarados. Hidden Power Ground may be used to hit Heatran and Infernape, although you have to predict the switch-in for Infernape. Focus Blast can be used to hit Tyranitar, Lucario, and Weavile for super effective damage, although the accuracy is a large letdown for Blissey. Hidden Power Fighting may be used for Tyranitar, though it's still better to switch out. Grass Knot may be used to predict a Tyranitar switch-in, but it's usually too threatening for Blissey to stay in on. All of these moves are best used as a surprise attack.

Counter can also work as a surprise move, although it generally only works once because the opponent will use a stronger physical move next time. Charm can be used to reduce the physical blows, although it is incompatible with Seismic Toss due to breeding restrictions. Heal Bell may be used in place of Aromatherapy, as Blissey cannot have Wish and Aromatherapy on the same moveset, because Wish is an event move and Aromatherapy is an egg move. Stealth Rock can be used should your team not have another Pokemon that can set it up. Blissey usually has free turns to set up Stealth Rock and can set them up again even if they are Spun away due to the number of times Blissey can switch in and out. Psych Up can steal opposing Jirachi and Suicune's Calm Mind boosts, while Calm Mind lets Blissey boosts her own stats. Snatch can be used to steal stat up moves, Substitute, Reflect, and Light Screen. Blissey can also use Gravity extremely well, as she can come back in several times thanks to Softboiled or Wish.

Ubers

Blissey has a bundle of other support moves for use in Ubers. She is one of the few usable Pokémon in Ubers that has access to Stealth Rock. While Blissey is often better off using other support moves besides Stealth Rock, it is a viable move if no other Pokemon on your team can set it up. Light Screen may seem like an odd choice on Blissey, but it can be helpful for not only support the rest of your team, but will also make sure that Choice Specs Kyogre will no longer be able to 2HKO Blissey while Light Screen lasts. Blissey can use Sing to put would be counters to sleep, but note that Sing only has a 55% chance of hitting the opponent. Snatch can be used to steal Reflects, Light Screens, stat ups, and other support moves, but many users of such moves such as Mewtwo can easily use Taunt to shut down that strategy, in addition to Blissey often being better off using Calm Mind herself rather then stealing Calm Minds. Rest is almost always an inferior option to Softboiled or Wish, but it can work well with Natural Cure, allowing Blissey to be relativity unharmed by Toxic Spikes, and will allow Blissey to outstall opposing Blissey. Blissey can use Block to trap Wobbuffet switch-ins, and then use Toxic to slowly stall Wobbuffet to death. Copycat may seem like a strange option on Blissey, but it can be useful in certain situations. For example, it can allow Blissey to use Spikes or Toxic Spikes on Forretress as it uses them. If Forretress attempts to Rapid Spin, you can either roast it with Flamethrower (provided that its sunny), or Copycat Rapid Spin to get rid of the opponents entry hazards. Copycat can also allow Blissey to defeat Calm Mind Giratina-O and Calm Mind Kyogre that lack Rest. Note, however, that Copycat is illegal with Seismic Toss and Wish.

Charm can be used to soften physical attackers attempting to prey on Blissey after a switch-in. Due to Charm, mixed Palkia (barring a Focus Punch) and Dialga will no longer be able to get past Blissey beyond scoring a critical hit, while Groudon and Garchomp will only have a small chance to 2HKO Blissey with a Choice Banded Earthquake and Outrage respectively. Note that both Garchomp and Groudon have access to Swords Dance, thus it is best to still have Pokemon that can defeat both. While an Adamant Life Orb Rayquaza can still 2HKO Blissey with Outrage after being hit by Charm, you can OHKO Rayquaza with Ice Beam after it switches into Stealth Rock and Charm (provided you have 84 SpA EVs), allowing Blissey to defeat a Pokemon that she is normally greatly troubled by. Charm also has the potential to cause a large amount of switches, thus it is best to pair Charm Blissey with users of entry hazards. Note that both Wish and Seismic Toss are illegal to use with Charm.

Blissey has access to Gravity. Gravity will allow both Groudon and Garchomp to freely use Earthquake and a 100% accurate Stone Edge, as Gravity eliminates the immunity Flying-type Pokemon and Pokemon with the Levitate ability for five turns. Gravity will also eliminate the immunity floating Pokemon have to Spikes and Toxic Spikes, meaning that Gravity Blissey will greatly benefit Forretress and Skarmory's Spikes (and Toxic Spikes in Forretress' case) laying abilities. Finally, Gravity will lower the evasion of all Pokemon by 2 stages, meaning that any move that has at least 60% accuracy will always hit. This is especially great for Darkrai, who must often use the 70% accurate Focus Blast and the 80% accurate Dark Void. Calm Mind Mewtwo with Life Orb will also enjoy the effects of Gravity, as it allows Life Orb Mewtwo to safely use Focus Blast, which will always 2HKO opposing Blissey after one use of Calm Mind. Garchomp not only benefits from an Earthquake that hits all Pokemon, it also enjoys the evasion cut as well. This is because the usually unreliable Dragon Rush becomes viable on Garchomp under Gravity, meaning that it will have access to a STAB 100 Base Power Dragon-type attack that has a 20% chance to flinch. Blissey's Sing will also hit 92% of the time under Gravity. There is one potentially fatal flaw with Gravity, and it is that the opponent can also take advantage of Gravity's effects. This will make Groudon and Garchomp particularly difficult to handle, thus it is best to either destroy them before using Gravity.

Blissey has some alternate attacks at its disposal that can be useful in certain situations. When under the support of Groudon's everlasting sun, Flamethrower becomes a viable option to KO or cripple several common Steel-types that may switch into Blissey. Forretress is always OHKOed by Flamethrower after Stealth Rock, while only extremely specially defensive Scizor will survive Flamethrower after Stealth Rock damage. Blissey's Flamethrower will do a massive 76% - 90% to Lucario in the sun, while Metagross is always 2HKOed after Stealth Rock damage. Grass Knot may normally be an inferior option to Thunder on Calm Mind , but it has two main selling points. Grass Knot is always a 100% accurate attack, regardless of the weather, which is particularly useful considering the fact that many Ubers are heavy enough to be hit by a 120 Base Power Grass Knot. Secondly, Groudon is hit quite hard by it. Finally, Counter can be a good option on Blissey, even in Ubers. Several Pokemon, such as Palkia and Dialga, will use mixed sets just to defeat Blissey. If Blissey predicts a physical attack from either of them, and uses Counter, Palkia and Dialga are sure to be KOed. Also, note that defensive Groudon, Choice Scarf Garchomp, and Scizor that lack Superpower are also unable to OHKO Blissey, meaning that Blissey will be able to gain a surprise kill on them if she is healthy.

EVs

OU

Blissey always needs 252 Defense EVs, as by investing in Defense you more than double Blissey's ability to take physical hits. In fact, 252 Defense Blissey takes neutral physical hits about as well as 252 HP Scizor or Spiritomb. Meanwhile, most Blissey sets want a Calm nature. The Calm nature allows Blissey to not get 2HKOed by such things as Choice Specs Gengar's Focus Blast, Choice Specs Lucario's Aura Sphere, or Choice Specs Flash Fire boosted Fire Blast from Heatran. In comparison, the defensive boost from a Bold nature is miniscule when compared to a Calm nature on Blissey.

The Diverse Blissey's EVs are reminiscent of the ADV era, where Blissey didn't have to invest in Special Defense in order to wall those types of attacks. However, with the advents of Choice Specs and stronger special attacks, it is wiser to use a Calm nature and boost Blissey's Special Defense. The disadvantage of using a Calm nature is that Blissey can be 2HKOed by a Choice Band Adamant Dugtrio. However, Blissey can stall out Earthquake with Wish + Protect or Toxic + recovery. She can also use Ice Beam to take down Dugtrio in one hit. The risk of this is low though due to some Dugtrio choosing to use Life Orb so it doesn't become Pursuit bait and other Dugtrio choosing to use a Jolly nature to outspeed more Pokemon.

Ubers

In the Uber tier, Blissey should use 4 HP / 252 Def / 252 SpD with a Calm nature on all sets without Ice Beam, as Blissey needs to be extra durable to take the powerful assaults of Ubers. If using Ice Beam, use the EV spread of 252 Def / 84 SpA / 172 SpD, because this will allow Blissey to OHKO a 0 HP / 4 SpD Rayquaza 100% of the time after it switches into Stealth Rock.

Opinion

OU

Blissey is still the best special wall in the game. With an enormous base 255 HP stat and a large base 135 Special Defense stat along with recovery in either Softboiled or Wish and Protect, opposing special attackers often switch out because they can't break Blissey. Snorlax is another formidable special wall, but it lacks an instant recovery move and must use Rest in order to heal. Cresselia is a good general wall, but the prevalence of sandstorm in the OU metagame reduces Moonlight's effectiveness and forces her to often use Rest like Snorlax. Blissey will therefore be a welcome addition to any team that is weak to opposing special attackers and is the best choice to counter many special threats at once. It's one thing if you "hate Blissey", but there is no other Pokemon that can replace her; she's that good at her job.

Ubers

Even in the Ubers tier, there is no Pokémon that can do Blissey’s job better. Although there are several Pokémon that can break through Blissey’s Special Defenses in Ubers, don’t let that discourage you from using Blissey, as it is still the best general special wall in the Ubers metagame. Almost any team will appreciate Blissey’s ability to sponge special assaults, especially stall teams.

Counters

OU

Machamp can easily switch into any Blissey, as RestTalk Machamp can heal off status and can DynamicPunch Blissey. Guts versions actually get boosted by either Toxic or Thunder Wave. Heracross is in a similar boat as Machamp, except it doesn't like paralysis as much. Electivire can switch into Blissey's Thunder Wave and deal large amounts of damage with Cross Chop. Scizor can use non-Flamethrower Blissey as setup bait, while Lucario can do the same. They can also immediately threaten Blissey with a Superpower or a Close Combat respectively. Choice Specs Lucario can also threaten the Diverse Blissey set, as it has a chance of 2HKOing her with Aura Sphere. Infernape can also easily Close Combat Blissey for a KO. Breloom can come in on a status move once it has been poisoned from Toxic Orb and threaten Blissey with Superpower or Spore.

Snorlax, Metagross, and Tyranitar don't mind being paralyzed and can hit Blissey hard with their STAB attacks or Pursuit. Salamence can 2HKO Blissey with Brick Break or Outrage and can OHKO Blissey with Outrage after a Dragon Dance. Dugtrio can trap Blissey if she's at a low enough HP. Togekiss with Nasty Plot, Roost, and Heal Bell can set up on Blissey, as Heal Bell cures paralysis and poison while Roost heals off any potential attacks. Substitute Gengar and Rotom-A can come in on an attack besides a status move and set up a Substitute to block further status moves. Gengar can then Focus Punch while Rotom-A can boost its Special Attack with Charge Beam and potentially 2HKO Blissey with Thunderbolt.

Celebi and Shaymin can use Leech Seed to stall out Blissey. Celebi can then set up Calm Minds, while Shaymin can use Seed Flare to get a Special Defense drop and KO Blissey. Taunters can easily stop Blissey, preventing her from healing or statusing. Gliscor, Gyarados, and Tyranitar can all Taunt Blissey and either setup on her or outright attack her. Pokemon that learn Trick can also cripple Blissey, preventing her from walling attacks as easily. Gengar, Rotom-A, and Latias can all utilize Trick to pass over a Choice item to Blissey.

Ubers

In the Uber tier, Bulk Up Dialga is, without a doubt, the best Blissey counter. It is immune to Toxic and can easily set up on Blissey. Powerful physical attackers such as Garchomp, Groudon, and Rayquaza can make Blissey’s life a living hell. However, Ice Beam will do massive damage to Garchomp and Rayquaza and none of them will like being hit by Toxic.

Many Pokémon in the Uber tier can surprise Blissey with mixed attacking sets, such as Mewtwo, Darkrai, Dialga, Palkia and Giratina-O. Dialga in particular can be a problem, as it is immune to Toxic.

If Blissey lacks Calm Mind or Psych Up, Kyogre and Giratina can use a combination of Sleep Talk, Rest, and Calm Mind to easily set up on Blissey. Kyogre, Mewtwo, and Giratina-O can also use Substitute and Calm Mind to beat her. In the rain, Manaphy can easily set up Tail Glow on non-Calm Mind Blissey and 2HKO it with a +2 Surf. Choice Specs Kyogre also has the capability of 2HKOing Blissey with Water Spout.

Wobbuffet can switch into Blissey and use Tickle several times to lower its Defense. After this, Blissey will be KOed by Pursuit from Scizor or Tyranitar. Wobbuffet can also use Encore on Blissey and switch in a sweeper such as Lucario or Giratina-O to take advantage of the free set up time.
