* Giratina-O is one of the premier Defog users in the tier and is commonly found on many balanced teams due to a formidable combination of utility options it provides.
* Great bulk, Levivate, and a defensive typing of Ghost / Dragon make Giratina-O a check to many physically oriented threats, such as Primal Groudon, Swords Dance Arceus formes, Necrozma-DM, Ho-Oh, and Mega Salamence.
* When accounting for Giratina-O's solid defensive typing, enormous bulk, inability to be trapped, access to various status moves, and, most importantly, offensive presence, there are very few Pokemon in the tier that can reliably set entry hazards against, switch into, or combat it.
* An advantageous matchup against the most relevant Stealth Rock user, Primal Groudon, is one of the major factors to Giratina-O's viability as a Defog user as well. Many Pokemon on balanced teams struggle to properly deal with Primal Groudon due to a large number of sets it can run to circumvent its checks, and Giratina-O stands as one of the safest switch-ins to Primal Groudon due to its ability to handle most variants.
* An ability to defeat common threats like Primal Groudon, Necrozma-DM, and many support Arceus formes in one-on-one scenarios, depending on its moveset, serves as Giratina-O's other attractive trait to balanced teams that need a Defog user capable of restricting many Pokemon from taking advantage of it.
* Giratina-O's effectiveness as a check to threats it pivots into will vary depending on its health due to its tendency to handle its foes offensively or with status moves. An average Speed tier means that Giratina-O will likely be attacked before it is able to counteract, which combined with a complete lack of recovery and an obligation to pivot into strong powerhouses like Primal Groudon makes its health management important.
* Prevalent special attackers like Xerneas, Yveltal, and Mega Gengar and other special attackers like Lunala and Deoxys-A can easily overwhelm Giratina-O and threaten to OHKO or heavily impair it. Other common offensive threats like Marshadow and Outrage Ultra Necrozma can exploit Giratina-O's weaknesses to circumvent its bulk.

* Giratina-O's ability to force switches with its strong attacks and check Primal Groudon makes it an effective Defog user.
* Hex provides Giratina-O with an immensely powerful attack against statused foes. Hex is one of the major factors that contribute to Giratina-O's offensive presence due to it 2HKOing foes like Primal Groudon, Primal Kyogre, Magearna, and the majority of the support Arceus formes once they've been statused.
* Dragon Pulse is a consistent secondary STAB move that isn't reliant on status. Dragon Pulse also has a sizable damage output despite its mediocre Base Power, doing enough damage to 2HKO most offensive Primal Groudon variants after Stealth Rock damage and outright OHKO offensive Mega Salamence.
* Draco Meteor provides Giratina-O with a Dragon-type STAB attack with more immediate damage output, forcing recovery moves from support Arceus formes that attempt to absorb damage and threatening to OHKO Yveltal and offensive Ho-Oh after Stealth Rock damage. Draco Meteor also pressures Primal Groudon significantly harder than Dragon Pulse, weakening defensive variants to the point where it can no longer pivot into threats like Necrozma-DM and Xerneas and putting offensive variants in range of priority moves. However, its tendency to force Giratina-O out after attacking a foe and worsen its matchup against Substitute Extreme Killer Arceus makes it a less favorable move than Dragon Pulse.
* A status move is used in the fourth moveslot to enable Giratina-O to use boosted Hex and punish a variety of its switch-ins. Thunder Wave cripples support Arceus formes, Yveltal, and Xerneas, making them much easier to check. Paralysis allows Giratina-O to threaten support Arceus formes by threatening to 2HKO them with boosted Hex, and it comes in handy with punishing Xerneas, forcing Choice Scarf variants to lock themselves into Aromatheraphy and making Geomancy variants significantly easier to handle. Thunder Wave especially comes in handy where Giratina-O isn't healthy enough to win duels against foes like Mega Lucario, enabling its teammates to handle them more easily.
* Will-O-Wisp is an alternative status move that pressures Steel-types harder with residual damage and cripples Necrozma-DM, Mega Lucario, and Swords Dance Arceus formes.
* Toxic can be used to pressure Primal Groudon and punish Giratina-O's checks harder in the long run, serving as the only status move that can pressure support and Calm Mind variants of Arceus-Ground, which would otherwise not mind too much about Giratina-O's other moves. However, choosing Toxic as a status move removes Giratina-O's ability to 2HKO specially defensive Necrozma-DM, and it is usually better for Giratina-O to use Thunder Wave or Will-O-Wisp and let its teammates spread Toxic poison to foes like Primal Groudon and support Arceus formes.
* Giratina-O can forgo Hex for Shadow Ball and give up a status move for Shadow Sneak to have a consistent Ghost-type STAB attack and a priority move, which can be handy with picking off faster threats like Mega Gengar and Deoxys-A and setup sweepers. A combination of Shadow Ball and Shadow Sneak is also capable of preventing Cloyster from setting up entry hazards. Note that Giratina-O will have to opt for a Quiet nature with this option to maximize Shadow Sneak's damage.
* Giratina-O's very high HP stat means it is better to improve its overall physical bulk with maximum Defense investment to survive boosted attacks from Necrozma-DM and Swords Dance Arceus-Ground.
* Maximum Special Attack investment with a Modest nature, combined with a mandated Griseous Orb to improve Giratina-O's offensive presence, limits its switch-ins and enables it to offensively check a large portion of the tier.
* Running 152 Speed EVs may be an appealing option if using Will-O-Wisp, as this enables Giratina-O to burn Necrozma-DM before Necrozma-DM OHKOes Giratina-O with +2 Searing Sunraze Smash. Note that this costs a noticeable portion of Giratina-O's damage output or bulk, however.
* Maximum HP investment can be used at the cost of damage output to take special attacks better. This can come in handy against mixed Primal Groudon running maximum Special Attack investment, which can otherwise overwhelm Giratina-O with repeated Fire Blast and even 2HKO it with Eruption on the switch.
* Levitate provides Giratina-O with an immunity to Ground, improving its matchup against Primal Groudon and Swords Dance Arceus-Ground.
* Making the best use of Giratina-O requires somewhat cautious play, despite it often being a pivot that is intentionally sent out against Primal Groudon and certain entry hazard setters. Giratina-O will inevitably sustain damage and will be worn down over the course of the match, and this means Giratina-O should be somewhat focused on managing its HP.
* Giratina-O should be quick to decide whether combating a foe and taking damage outweighs lessening the chance it can take on other threats it may be tasked to handle. Taking damage and removing entry hazards with Defog is beneficial for Giratina-O's team, but staying in the field unnecessarily long to take an extra attack or increase the odds of getting inflicted by status will only make Giratina-O get worn down faster.
* Primal Groudon and Swords Dance Arceus formes are the most common foes that Giratina-O should stay in against to prevent them from dealing excessive damage to other teammates. While these threats may be easier to keep in check with a healthy Giratina-O when they attempt to wallbreak early- or mid-game, it will be much more difficult to stop them as the game gets longer and Giratina-O keeps taking damage. Unless there are reliable checks to said foes other than Giratina-O, ensure that Giratina-O is healthy enough to win the duel against them.
* Against bulkier teams with durable entry hazard setters like defensive Necrozma-DM, Ferrothorn, and Arceus formes using Stealth Rock, Giratina-O can choose to act aggressively by statusing them and then damaging them with Hex. While entry hazard setters from bulky teams tend to carry Toxic, this may be a worthwhile move to make if entry hazards are going to be problematic for Giratina-O's team and the setters have to be pressured.
* Giratina-O will find an opportunity to remove entry hazards from offensive teams if it manages to pivot into an appropriate foe like Primal Groudon or Arceus-Ground. As these Pokemon are common in such archetypes and simply letting Giratina-O switch into them will let it remove entry hazards set by dedicated leads, it is likely that an opponent will seek a way to wear down Giratina-O with Stealth Rock and aggressively double switch into offensive checks like Xerneas and Yveltal, so avoid being too reactive against such teams.
* Various support Arceus formes can be beneficial, as, depending on their typing, they can cover Giratina-O's weaknesses and form a good defensive core. With Giratina-O freeing their moveslot by providing Defog support, Arceus formes have more options to be better checks to whichever foe they desire to cover for the team and can cover foes like Zygarde-C and Mega Salamence that will either force Giratina-O to directly combat them to keep them in check or overwhelm it after some prior damage. Arceus-Water is the most notable one, as it can handle most Primal Groudon variants with Giratina-O and can sponge attacks from special variants of Primal Groudon and Ho-Oh, which Giratina-O cannot switch into consistently. Arceus-Dark soft checks Necrozma-DM and Yveltal while benefiting from Giratina-O drawing in and statusing checks like Xerneas.
* Various Steel-types like Necrozma-DM and Ferrothorn can pivot into Toxic and Fairy-type attacks aimed at Giratina-O. Practically any Steel-type appreciates Giratina-O's ability to stand against Primal Groudon and can set entry hazards or spread status in return. Magearna is a notable partner that can pivot into both Xerneas and Yveltal, provide cleric support, and benefit from Giratina-O's Defog support, preventing Spikes from rapidly wearing it down.
* Stealth Rock users like Primal Groudon and Necrozma-DM can prevent defensive Ho-Oh and Yveltal from recklessly switching into Giratina-O and can run Toxic to cripple Defog users and support Arceus formes, giving Giratina-O an easier time to deal with foes that it would need poisoned to deal with.
* Flying-types enjoy Giratina-O's Defog support and can also function as secondary checks to Primal Groudon offensively or defensively. Ho-Oh is one of the Pokemon that benefit the most from the absence of Stealth Rock to be able to pivot into Fairy-types, absorb status moves reasonably well, pressure Steel-types, check some Primal Groudon variants, and spread status to make Giratina-O's Hex easier to utilize. Yveltal offensively checks Ghost-types, cripples special walls with Taunt, and benefits from Giratina-O's ability to leave Arceus formes crippled by status or a large amount of damage they took while combating it. Mega Salamence can absorb status moves for Giratina-O to use boosted Facade and can have a better chance to sweep after its checks like Steel- and Fairy-types have been pressured by Giratina-O.
* Mega Gengar and Giratina-O can work together to spread various status ailments and facilitate their attempts to prey on as many foes with boosted Hex as possible. Mega Gengar can trap and dispose of Fairy-types and special walls, while Giratina-O can pivot into threats like Primal Groudon and Ho-Oh that Mega Gengar struggles to deal with. Trapping and removing Stealth Rock users like Arceus-Fairy that Giratina-O cannot effectively deal with is also appreciated.
* Toxapex can set Toxic Spikes to ease Giratina-O's attempts to damage foes with boosted Hex, take advantage of Arceus-Fairy, and check Marshadow and Ho-Oh. In return, Giratina-O can pivot into Ground-type attacks aimed at Toxapex.
* Cleric support from Xerneas, Chansey, and Blissey can be helpful to prevent Giratina-O from losing too much HP from status. Chansey and Blissey can also support Giratina-O with Wish to further extend its longevity.
* A physically based set with Defog, Dragon Tail, Shadow Sneak, and Earthquake or Shadow Force provides Giratina-O with a stronger priority move and a way to 2HKO Magearna without statusing it beforehand. However, this set is helpless against Fairy-types, struggles to combat Primal Groudon, and is easily taken advantage of by Ferrothorn. Dragon Tail's inability to prevent Extreme Killer Arceus from setting up with Substitute against Giratina-O also leaves this option fairly disappointing.
* Magic Coat can be used to reflect status and entry hazard moves from suicide leads like Deoxys-S and various Pokemon that rely on Toxic to combat Giratina.
* Rest is Giratina-O's only form of recovery, but it can only be used effectively with cleric support, and Giratina-O has a hard time justifying its use over any listed move. As Giratina-O is immobile while asleep, Rest ends up being a detriment due to the sleep turns and its tendency to allow Giratina-O's offensive checks to switch in freely, along with entry hazard setters taking advantage of Giratina-O without fear.
* Roar can be used to deal with setup sweepers behind Substitute and possibly make Geomancy Xerneas waste its Power Herb, but this move is very hard to fit.
Checks and Counters
**Fairy-types**: Both Xerneas and Magearna can switch into Dragon-type moves and threaten Giratina-O with their STAB moves. Both of them also have access to cleric moves to cure status that Giratina-O aims to spread as well. However, Choice Scarf Xerneas with Aromatherapy will be forced to heal its status right away if switched into Thunder Wave, and Geomancy variants will be punished harder if switched into said move. Arceus-Fairy has access to recovery moves to consistently switch into Giratina-O, but it has similar concerns about getting paralyzed, which will make it vulnerable to getting 2HKOed by boosted Hex from Giratina-O.
**Dark-types**: Offensive Yveltal can cleanly OHKO Giratina-O with Dark Pulse, and defensive variants typically carry Taunt that prevents Giratina-O from using Defog or status moves. However, Yveltal dislikes switching into Thunder Wave and Toxic, and offensive variants have to be wary about switching into Draco Meteor when Stealth Rock is up. Arceus-Dark has enough bulk to take on most Giratina-O variants, and variants carrying Refresh does not mind Giratina-O at all, apart from being forced to use Recover after switching into Draco Meteor. Tyranitar can force out Giratina-O while setting Stealth Rock and additionally guarantee a heavy hit on it with Pursuit. Even after getting burned, Tyranitar is a huge nuisance for Giratina-O due to the residual damage from sandstorm and potential Toxic.
**Chansey and Blissey**: Both Chansey and Blissey have enormous special bulk to take any attack from Giratina-O with ease, Natural Cure to absorb status, and Heal Bell to heal its teammates of status ailments.
**Ghost-types**: While Ghost-types almost never find opportunities to switch into Giratina-O, they can offensively check it if given a safe switch. Mega Gengar, Lunala, and Marshadow are all able to threaten Giratina-O, but they must be wary of Shadow Sneak and avoid switching into Thunder Wave.
**Super Effective Attacks**: Super effective moves like Ice Beam from Arceus formes prevent Giratina-O from effectively dealing with them, while more offensive foes like Ultra Necrozma, mixed Rayquaza, Palkia, and Dialga can threaten to OHKO Giratina-O with their super effective attacks.
**Status**: Giratina-O's already limited longevity is further worsened by burn and poison, and paralysis can be detrimental as well due to its potency to potentially prevent Defog.
