[OVERVIEW]
Dialga is a slow powerhouse that has good offensive stats and decent defensive stats, allowing it to run both offensive and defensive sets. With an offensive set, Dialga can pressure the opponent with STAB Doom Desire and wallbreak late-game with Tail Glow boosts, setting up on various Steel-types, Water-types, and slow Pokemon like Mega Audino. Because Dialga isn't weak to Fire, it doesn't feel obliged to run Flash Fire on its sets like other Steel-types, giving it the option to run other abilities instead. Defensively, its RegenVest set easily fits onto many team archetypes because it can remove entry hazards, steal boosts with Spectral Thief, disable the foe's ability, paralyze the foe, and most importantly, pivot out. Also, thanks to its Steel / Dragon typing, Dialga serves as a nice check to many top threats in the metagame, namely Mega Mewtwo Y, Primal Kyogre, Mega Rayquaza, and Normal-types. The efficacy of these sets, however, depends also on the level of support Dialga can get from its teammates. Its offensive sets require a lot of support due to how easily they can be revenge killed. When using Dialga, you should always be wary of Fighting- and Ground-type attackers like Mega Mewtwo X and Red Orb Groudon and should play accordingly. Pokemon with common Ground and Fighting coverage such as Precipice Blades Mega Diancie and Secret Sword Mega Mewtwo Y can threaten Dialga. Also, Dialga's offensive sets are hindered by the passive mechanics of Doom Desire and Dialga's relatively slow base 90 Speed. Despite all this, Dialga still manages to be extremely useful in the right circumstances and should not be underestimated.

Moves
========
Doom Desire is an extremely powerful Steel-type move that hits two turns after being used, allowing Dialga to play mind games and put tons of pressure on the opponent. Doom Desire also discourages certain Pokemon like Mega Diancie, Mega Audino, and Giratina from switching in immediately, encouraging Pokemon like Mega Mewtwo X to come in. Tail Glow boosts Dialga's Special Attack by three stages and goes well with Doom Desire as next to nothing can take a +3 Doom Desire. Core Enforcer is Dialga's Dragon-type STAB move as it is the most reliable special Dragon-type move with no drawbacks and can also disable the enemy's abilities if Dialga moves last. Though the move is mainly used for damage because of Dialga's Speed investments, it does allow Dialga to force even faster foes out by disabling their abilities, like Poison Heal for example, which works well in conjunction with using Doom Desire. Draco Meteor hits significantly harder than Core Enforcer and can OHKO Mega Rayquaza, but this comes at the cost of lowering Dialga's Special Attack. Doom Desire and Dragon STAB make Dialga a powerful offensive threat, as next to nothing can take a +3 Doom Desire and a +3 Core Enforcer together as they both already deal massive damage individually. Shore Up keeps Dialga healthy for longer, allowing it to break through more walls and assist its teammates more often with Doom Desire. Dialga can also use King's Shield or Baneful Bunker over Shore Up or Core Enforcer, but it will lose out on longevity or wallbreaking power, respectively. King's Shield weakens physical attackers and can prevent U-turns while Baneful Bunker can wear down non-Steel type walls and Shedinja. King's Shield is generally preferred as it has a better effect against Poison Heal users and Steel-types, though King's Shield does not block status moves. These options allow Dialga to last even longer and give it the option to stall for turns while waiting for Doom Desire to hit, which can be especially useful after spending one turn using Tail Glow. Otherwise, Shore Up is preferred for longevity over these moves.
Set Details
========
Steelium Z allows Dialga to attack immediately with a 200-Base Power Corkscrew Crash, nailing opponents that think they're safe before Doom Desire hits and dealing massive damage to almost any opponent due to its ability. Due to Z-Moves being unaffected by Normalize, it can also hit Normalize Mega Gengar after it uses Entrainment. Safety Goggles can also be used to block the use of Spore, which makes Dialga more effective against Spore users like Mega Rayquaza and Deoxys-S and lets it block hail damage and other powder moves. However, Safety Goggles Dialga is still vulnerable to Lovely Kiss and must be wary of Knock Off users such as Poison Heal Regigigas and Poison Heal Slaking. For its ability, Tinted Lens allows Dialga to heavily pressure balanced and stall teams by hitting extremely common Steel-resistant Pokemon like Registeel and Primal Kyogre significantly harder, possibly even OHKOing them with Doom Desire after a Tail Glow boost. Steelworker lets Dialga's Doom Desire hit the neutral and weak targets more commonly found on offensive teams harder. It also allows Corkscrew Crash to do a ridiculous amount of damage even without a Tail Glow boost. Magic Bounce allows Dialga to check certain Pokemon like Triage Mega Rayquaza and Regigigas better as Dialga can bounce back their Spore, eliminating the need for Safety Goggles. It also bounces back Entrainment from Mega Gengar and various Steel-types as well as Topsy-Turvy. Fur Coat is an option that allows Dialga to stay in against a wider group of Pokemon. With doubled Defense, many 2HKOs will turn into 3HKOs and Dialga can set up against more Pokemon. Finally, Modest is used to maximize Dialga's Special Attack and make it as powerful as possible. You can also opt to run Bold, but you may resort to using Tail Glow more often to make up for lost power.
Usage Tips
========
Doom Desire only has 8 PP, so use it wisely. Dialga can use Tail Glow before Doom Desire hits in order to wallbreak by itself, or it can switch out to a teammate such as Mega Mewtwo X to support their wallbreaking ability, scare out Pokemon like Xerneas, and put immense pressure on the opponent. The latter plan of action is generally preferred early-game. Due to Doom Desire's unique mechanic of a delayed hit, Dialga can also opt to cast the move and then setup afterwards. Alternatively, because Doom Desire hits at the end of the second turn, Dialga can also attack in the beginning of the same turn or the following turn to deal massive damage and break through walls. If Imposter Chansey or a Spectral Thief user is on the team, Dialga can either use Core Enforcer instead of Tail Glow or switch out after using Doom Desire. However, even coordinated attacks are not always enough, so only bring in Dialga on passive Pokemon you intend on breaking through. If you are using Magic Bounce, you can target even more opponents, as passive Pokemon often carry bounceable moves like Stealth Rock, Will-O-Wisp, and Entrainment. Do not waste Corkscrew Crash. If your opponent has a Normalize Mega Gengar, wait to use Corkscrew Crash as it remains Steel-type even through Normalize and Entrainment and can be used as a check. Otherwise, just wait until the opportune time to use it, such as when a Fairy-type switches into Dialga. A +3 Corkscrew Crash can obliterate anything that doesn't resist it, but just be wary of RegenVest Pokemon and Unaware users, as they can usually absorb the attack.
Team Options
========
To Imposter-proof Dialga, Substitute Fairy-types like Poison Heal Xerneas and Poison Heal Mega Diancie are offensive options, while Unaware Primal Kyogre, Unaware Chansey, and Unaware Mega Gyarados are defensive ones. Dialga needs a teammate that can switch into Fighting-type moves as having a check or counter to Mega Mewtwo X is absolutely essential. A Ghost-type such as Giratina or even bulky Psychic-types such as Cresselia would work for this role. Dialga appreciates having another Steel-type such as Registeel and Flash Fire Solgaleo as support because it can't check Pixilate and Refrigerate Pokemon. Pokemon that can eliminate opposing offensive threats like -ate users in general do well with Dialga due to the fact that Dialga is not equipped to threaten these Pokemon and is subsequently forced out by them. Dialga pairs exceptionally well with other wallbreakers such as Mega Mewtwo X, Mega Diancie, and Mega Rayquaza, as they enjoy the pressure put on the opponent by the Doom Desire support. For example, Mega Rayquaza once again goes well with Dialga despite the type overlap because it can serve as an anti-offense Pokemon that's immune to Ground. Lastly, entry hazard setters, especially those that can pressure Magic Bounce users, can drastically improve the effectiveness of Dialga as most things that normally wall it will get quickly worn down with entry hazard damage. Entry hazards also help against Sturdy Shedinja, one of Dialga's hard counters. Mega Diancie can pressure Magic Bounce Pokemon as well as Defoggers such as Giratina. Mega Diancie itself can also work as an offensive teammate as Dialga can also help Imposter-proof it with Doom Desire. Mold Breaker Pokemon like Mega Garchomp can bypass Magic Bounce entirely to set hazards. Mega Garchomp in particular also pairs well with Dialga as Dragon-types like Mega Garchomp can spam their Dragon-type STAB moves without worry of Fairy-types coming in while Doom Desire is active. Red Orb Groudon can threaten Magic Bounce users by reducing their longevity with Sacred Fire burns. More defensive Pokemon like Ferrothorn can run Stealth Rock or Spikes as well, but these have a worse matchup against Magic Bounce users.

Moves
========
U-turn lets Dialga pivot out to a more offensive Pokemon to gain momentum, which is good considering that Dialga is moderately slow. Core Enforcer is a 100-Base Power STAB attack that can negate the abilities of faster foes, which is especially handy considering that Dialga either underspeeds or Speed ties with many other Pokemon in the metagame, especially most Dragon-types bar Zygarde-C. Revelation Dance becomes Steel-type for Dialga and can hit Mega Gengar even after it changes Dialga's ability to Normalize. It also threatens Fairy-types like Mega Audino and Xerneas. Spectral Thief lets Dialga steal boosts from Pokemon utilizing setup moves to prevent Dialga from getting overpowered too quickly. It also hits Mega Mewtwo Y, Aegislash, and Mega Gengar, which Dialga checks decently well. Rapid Spin can be used to get rid of entry hazards, as Dialga is difficult to spinblock due to it threatening two of the three most common Ghost-types, namely Giratina and Mega Gengar. Nuzzle can be used to paralyze targets, but it makes Dialga more difficult to Imposter-proof.
Set Details
========
A Sassy nature lets Dialga maximize its Special Defense and minimize its Speed. That alongside 0 Speed IVs lets Dialga be as slow as possible to ensure Core Enforcer usually hits last, to prevent Dialga from getting its own ability disabled by other Core Enforcer users, and to let Dialga be a slow pivot. 16 Speed EVs with a Careful nature is an alternative option that allows Dialga to steal Shell Smash boosts from various Pokemon and outspeed everything up to Mega Mewtwo Y at +2 Speed, as it can survive attacks from quite a few Shell Smash users provided they don't have STAB Power Trip or super effective coverage against Dialga. Dialga trades the ability to use status moves for more Special Defense with its Assault Vest. With a 1.5x Special Defense, it can take on many special attackers in the tier such as Primal Kyogre, Aerilate Mega Rayquaza, and Xerneas. Regenerator restores 33% of Dialga's HP every time it switches out, letting Dialga passively recover without wasting any turns. This works especially well with momentum moves like U-turn. Regenerator is an important ability on this set, as the passive healing makes up for Dialga's inability to use recovery moves because of its Assault Vest.
Usage Tips
========
RegenVest Dialga counters most special attackers that don't have super effective coverage against it, such as Primal Kyogre without Tinted Lens, Normalize Mega Gengar, No Guard Mega Mewtwo Y, and Xerneas lacking Earth Power. Its improved bulk allows it to switch into these threats and then heal over the course of the match by pivoting or switching out. If Dialga is at low health, utilize free turns against passive Pokemon by switching Dialga in then double switching or using U-turn. Always use U-turn liberally, as oftentimes, once your opponent knows your Dialga is defensive, they'll attempt to bring in walls because they know Dialga won't be able to do too much aside from use Core Enforcer. If they bring in a wall on the same turn Dialga pivots, you can bring in a wallbreaker and maintain momentum. If you predict your opponent is going to bring in something frail, you can try to get a 2HKO or 3HKO using a STAB move. Be wary of Knock Off, however, as Dialga gets significantly weaker if its Assault Vest is removed, so be careful around common Knock Off users such as Mega Audino and Mega Tyranitar even if Dialga has the type advantage. Don't waste Core Enforcer's mere 16 PP, as the move serves both an offensive and utility purpose. If you can't knock something out, pivot to something that can, as Dialga's main role is to provide momentum for the team through pivoting.
Team Options
========
Imposter Chansey can assist in scouting for sets that would threaten Dialga like Secret Sword Mega Mewtwo Y or Earth Power Triage Mega Rayquaza as well as various other threatening abilities like Adaptability. Dialga absolutely must have a teammate that can deal with Mega Mewtwo X, as Mega Mewtwo X can easily force out Dialga and set up if it predicts Dialga will switch. Mega Sableye, Giratina, and Mega Slowbro are all checks to Mega Mewtwo X. Zygarde-C can also beat most sets if it has Unaware or Prankster. It is also important to check Mega Diancie, as it is one of the few Fairy-types that can beat Dialga if it has Precipice Blades, and a Boomburst from Mega Diancie is a nearly guaranteed 2HKO with Stealth Rock damage. Ho-Oh beats the Pixilate variants of Mega Diancie, while Flash Fire Aegislash and Sturdy Shedinja beat Magic Guard variants. Red Orb Groudon can prevent Mega Diancie from becoming a problem, and it can also set entry hazards to beat one of Dialga's counters in Sturdy Shedinja. Red Orb Groudon also patches up any weaknesses against opposing Steel-types that Dialga faces and beats opposing RegenVest Pokemon with its powerful physical attacks. Besides Primal Groudon, Mega Mewtwo X can also deal with opposing Steel-types, as this variant of Dialga cannot threaten them at all. Dialga is also heavily threatened by Ground-types, so Mega Rayquaza can be used as it outspeeds and can threaten every relevant Ground-type.
RegenVest Dialga can fit on many team archetypes as it can passively recover health and support its teammates by pivoting, and can be paired with decently frail sweepers and wallbreakers like Mega Rayquaza and Mega Mewtwo Y. It also pairs well with teammates like Slaking, Mega Sableye, and Mega Rayquaza that are normally forced out by powerful special attackers. Dialga hates Spikes as they limit its pivoting ability and prevent it from walling stronger attacks like Mega Diancie's Boomburst and Tinted Lens Primal Kyogre's Steam Eruption. Thus, if Dialga doesn't run Rapid Spin, another teammate should run Rapid Spin or Defog. Dialga appreciates something that can absorb Knock Off, as its ability to wall is severely hampered if it loses its Assault Vest. Griseous Orb Giratina, Red Orb Groudon, and Pokemon with Z-Crystals cannot have their items knocked off. Unaware users such as Primal Kyogre, Mega Gyarados, and Mega Audino are also appreciated partners to Dialga as they can beat the setup sweepers that Dialga struggles with. This set is relatively easy to Imposter-proof, as many special walls like Primal Kyogre can easily switch into Imposter users transformed into Dialga, but a drawback is that Imposter users can come in and heal for free, which is why you may want something that can both switch in and force out Imposter Pokemon. A teammate with Poison Heal can help alleviate any issues with Nuzzle spreading status and Poison Heal also soaks other statuses that Dialga is weak to such as sleep from Spore. If you are not running Nuzzle, you can opt for a Safety Goggles teammate instead to check Spore users like Xerneas.
[STRATEGY COMMENTS]
Other Options
========
Adamant Orb is an option on the Doom Desire set, but Dialga appreciates the utility of Corkscrew Crash, so it's best to only use Adamant Orb if you need the Z-Crystal on another Pokemon. The power boost granted can be helpful against targets such as Zygarde-C and Giratina, but it can be removed with Knock Off. Leftovers provides passive recovery for the Doom Desire sets and can assist in stalling for turns while Doom Desire hits, but it poses the same issues as the Adamant Orb does due to the lack of Corkscrew Crash. Doom Desire Dialga can run a Quiet nature with minimum Speed investment to attempt to underspeed targets with Spectral Thief, but a lot of walls still underspeed it regardless like Mega Audino and Registeel. Contrary works on the Doom Desire set when spamming Draco Meteor and allows Dialga to forgo Tail Glow. However, without a Substitute Fairy-type, Contrary is harder to Imposter-proof, especially with the extra moveslot. Mold Breaker allows Doom Desire Dialga to break past Unaware Pokemon more easily and beat Shedinja, but it's very niche, as it's difficult to Imposter-proof without using Substitute Fairy-types. Adaptability boosts the power of STAB moves for Dialga's Doom Desire set, but it's only worth using if Dialga runs Core Enforcer too, as Steelworker makes Doom Desire stronger than Adaptability does. Anchor Shot is an option for the Doom Desire set over Tail Glow to PP stall Imposter users, but the set will be significantly weaker. U-turn is an option on the Doom Desire set, but Doom Desire sets struggle with four-moveslot syndrome.
Dragon Tail allows Dialga to phaze targets on the RegenVest set, but the moveset is already cramped and Dragon Tail is only worth it with entry hazard stacking. Knock Off is an option on the RegenVest variant and can hit Mega Mewtwo Y super effectively, but Dialga needs to worry about Imposter users removing its Assault Vest. Metal Burst is another option for RegenVest, as it can hit foes like a truck and works especially well for targets that 2HKO Dialga such as Sheer Force Mega Mewtwo Y, but the opponent will often play less aggressively against Dialga afterward, so it may not get much use. It does synergize well with Dialga's minimal Speed investment for that set, however. Other than that, RegenVest Dialga tends to be limited in its moveset because it holds an Assault Vest, and as such it can be one-dimensional at times.
Checks and Counters
========
**Shedinja**: Dialga generally doesn't run Sunsteel Strike or Mold Breaker and Shedinja underspeeds, making Core Enforcer useless. Any attack that Dialga hits Shedinja with is just shrugged off by Sturdy, and Shedinja can retaliate with Endeavor.
**Mega Mewtwo X**: Mega Mewtwo X takes little damage from unboosted Dialga, while most variants of it OHKO it back easily. Dazzling and -ate variants have a good chance to OHKO Dialga with Close Combat, while Contrary and Poison Heal variants have the same chances with Superpower and Low Kick. Technician and Choice Band variants easily get a guaranteed OHKO.
**Ground-types**: Mega Garchomp can't switch in, but walls can take advantage of Dialga's Speed to pivot into Mega Garchomp, which can in turn OHKO Dialga with ease. Primal Groudon doesn't like the risk of losing Desolate Land but can set up on RegenVest variants or just OHKO the Doom Desire ones. Zygarde-C doesn't like taking Core Enforcer, but Dialga doesn't like taking Thousand Arrows or Thousand Waves unless it's Fur Coat.
**Unaware Pokemon**: Primal Kyogre with Unaware is one Pokemon that can counter Dialga. Both sets lose to it, as Doom Desire from Tinted Lens Dialga fails to 2HKO Primal Kyogre and RegenVest often ends up just pivoting out. There are other Unaware users that can take its attacks, such as Mega Gyarados and Chansey, but none of them counter Dialga as well as Primal Kyogre does.
**Powerful Pokemon with Strong Coverage**: Pokemon with Contrary can hit RegenVest variants of Dialga harder each turn and the best thing Dialga can do is hope it survives to get a Core Enforcer off, but even then the Contrary Pokemon will still have boosts that will last a few turns before dissipating. Choice item users generally have the power to break past Dialga very quickly. Mega Mewtwo Y uses both Choice Specs and Contrary, and Mega Rayquaza uses Choice Specs or Choice Band. Also, Doom Desire Dialga hates Z-Move users like Dragonium Z Mega Garchomp and Mega Sceptile.
**Steel-types**: RegenVest Dialga has difficulty dealing with Steel-types in particular, and it's not uncommon for Dialga to get into stall wars with opposing RegenVest Steel-types. They resist both of Dialga's STAB move types and pretty much all of them underspeed Dialga, which is bad when Dialga wants to pivot.
**Water-types**: While Dialga isn't walled as hard by Water-types, Primal Kyogre, Mega Gyarados, and more niche ones like Mega Swampert can still take Dialga's attacks. Primal Kyogre flat-out walls RegenVest Dialga and Quiver Dance sets can threaten the Doom Desire set, but RegenVest Dialga can wall Primal Kyogre too unless the Primal Kyogre has Tinted Lens. Mega Gyarados can force out RegenVest Dialga with the threat of Knock Off, and while some sets are checked by Doom Desire, namely Fur Coat, the Choice Band, Unaware, and Unburden sets are not. Mega Swampert can threaten Dialga with Thousand Waves and usually runs Topsy-Turvy to prevent Doom Desire from beating it. All of these with the exception of Unaware Kyogre take fairly significant damage from Tail Glow-boosted Core Enforcer, however.
