[OVERVIEW]
Latias is one of the best Pokemon in the tier courtesy of its incredible Mega Evolution, posessing a useful speed tier, a solid Special Attack stat, and great bulk. Its typing alongside Levitate has unique attributes defensively that synergize well with these qualities, making Mega Latias one of the best checks to some of the most dangerous threats around like Kartana and Swords Dance Gliscor, while matching up well into others like Mega Medicham and Manaphy. This lets it run a fantastic utility set, taking advantage of its wide movepool of both offensive and support moves like Ice Beam, Thunder, Thunder Wave, and Defog, capitalizing on common switchins to inflict paralysis for its teammates. Alternatively, Mega Latias acts as a fantastic Calm Mind sweeper, using its fantastic longevity, including immunities to Spikes and Toxic Spikes, to wear down its checks like Heatran and Chansey with entry hazards and become unstoppable late-game, while its speed prevents wallbreakers like Tapu Lele and Kyurem-B from hitting it hard first. However, Mega Latias's typing also come with common weaknesses that hold it back: Its weakness to Fairy alongside its inability to hit many of them hard with its coverage moves gives entry to dangerous wallbreakers like Tapu Lele, Magearna, and Mega Mawile, its Bug weakness means that, despite its typing, it cannot switch in safely against the likes of Victini and Landorus-T lest it be hit heavily by U-Turn, and its Dark weakness lends a tendency to being Pursuit trapped by Tyranitar and Weavile. Utility sets can feel passive into defensive teams, with the likes of Clefable, Reuniclus, and Gastrodon to stomach its unboosted attacks, while Calm Mind sets can struggle to make progress against the likes of Heatran and Mega Tyranitar without entry hazard support. Finally, Mega Latias is terrified of paralysis and poison, both completely shutting it down by negating its incredible speed and undermining its longevity respectively.

Moves
=========
Ice Beam is mandatory on Mega Latias, OHKOing crucial targets like Landorus-T, Gliscor, and Garchomp, hitting Kartana, Serperior, and Tornadus-T hard, and providing generally solid neutral coverage against the likes of Tapu Koko and Excadrill. Thunder forms solid coverage with Ice Beam, hitting Water-types likes Tapu Fini and Manaphy, benefitting from perfect accuracy on the rain teams the latter finds itself on, and provides neutral damage and a noteworthy Paralysis chance against switchins to Ice Beam like Mega Mawile and Magearna. Draco Meteor is Mega Latias's strongest attack, and is particularly useful against offensive threats like Weavile, Mega Medicham, Kyurem-B, and Mega Charizard X, who could otherwise survive any of Latias's other attacks at high HP. Psychic is Mega Latias's most spammable move into neutral targets, hitting the likes of Tapu Koko and Clefable slightly harder than Ice Beam or Thunder, 2HKOing Toxapex, and OHKOing Hawlucha. Mega Latias can also make use of Hidden Power Ground to hit Heatran particularly hard or Hidden Power Fighting to reliably OHKO Kartana and thwart the efforts of Tyranitar and Weavile to Pursuit trap it, 2HKOing the former and OHKOing the latter from full HP. Thunder Wave provides a consistent way to apply Paralysis, which cripples common switchins like Magearna, Heatran and Mega Scizor, and neutralises offensive threats like Calm Mind Mega Alakazam and Mega Charizard X. Roar is an alternative to handle setup sweepers, notably answering Calm Mind Reuniclus, and can be used with Spikes and Stealth Rock support to accrue passive damage. Mega Latias is also a solid user of Defog courtesy of its immunity to Spikes, Toxic Spikes, and Sticky Web, neutrality to Stealth Rock, and good matchup into hazard setters like Rockium Z Garchomp, Landorus-T, and Skarmory to reliably clear hazards for teammates. Finally, Recover is mandatory for keeping Mega Latias healthy so it can perform its defensive duties.

Moves
=========
WIth Calm Mind, Mega Latias becomes a strong wincondition in the late-game once its checks are worn down, while it keeps itself healthy with Recover. Stored Power becomes almost unstoppable after multiple boosts from Calm Mind, breaking through even bulky resists like Mega Scizor. Psyshock is slightly more reliable as it still outputs solid damage when unboosted, with advantages such as immediately threatening Toxapex with a 2HKO, preventing it from switching in to Haze its boosts away or threaten a Toxic. Thunder is an option over both moves to play to Mega Latias's early-game switchins to potentially net a paralysis on checks switching in like Magearna and Heatran to ease its late-game sweeping and lets Latias beat Slowbro that carry Toxic. However, it makes breaking through opposing Calm Mind users like Clefable, Reuniclus, and Cresselia much tougher without the use of Stored Power or Psyshock to negate their boosts. Ice Beam allows Latias to retain its ability to answer Kartana, Garchomp, and Gliscor, while hitting the likes of Ferrothorn and Excadrill for greater damage.

Usage Tips
========
A key part of what makes Calm Mind Mega Latias so effective is how it functions as both a late-game sweeper and early-game defensive piece; it should hence be used as such to take on threats to the rest of its team. This also serves the dual function of bringing in its checks like Celesteela, Heatran, and Magearna to weaken them usingentry hazards, Ice Beam chip damage, or paralysis if using Thunder. However, if it wants to plan for a late-game sweep, it needs to avoid taking on Pokemon that can cripple its chances, such as switching into Glare Serperior or Toxic Heatran; It may also be advantageous to switchin to an anticipated burn if it means avoiding a more debilitating status condition. Keep in mind that although Latias is able to break past opposing Calm Mind users, especially Reuniclus, when wielding +6 Psyshock or Stored Power, it cannot switch into them first and act as a check lest it get defeated by its own Psyshock.
Team Options
========
Calm Mind Mega Latias fits best on Semi-Stall and Balance teams which can use entry hazards or other teammates to wear down its checks for Latias to break through them eventually. Ferrothorn and Skarmory are fantastic users of Spikes, which wear down the likes of Magearna, Heatran, and Mega Scizor and themselves possess great bulk and longevity. Ferrothorn can check the likes of Tapu Lele and Magearna which Latias invites switchins to, while Skarmory helps relieve pressure from Latias against the likes of Choice Band Kartana and Dragonium Z Garchomp, especially when these Pokemon are paired with Pursuit support from Tyranitar and Weavile that threatens to eliminate Latias prematurely.

Other Options
=============
Both sets can opt for Thunderbolt in place of Thunder, trading the latter's higher power and paralysis chance for more reliability, although Latias's bulk and multiple switchin opportunities means it can often afford to miss a few Thunders. Earthquake is an option on the utility set that hits Assault Vest Magearna and Heatran particularly hard on their lower Physical Defense, but is generally weak otherwise and can have its power negated by Grassy Terrain and Burn, which Latias shouldn't have issues with. Reflect is another option that provides a temporary buffer against Physical Attackers for Mega Latias and its teammates against the likes of Mega Medicham's Ice Punch, and can be used anticipating Weavile or Tyranitar switching in to avoid heavy damage from Pursuit, but it lacks progress-making potential compared to Thunder Wave, Roar, and Defog.
The Calm Mind set can use Stored Power as the only attack and forgo Ice Beam, replacing it with one of Substitute, Refresh, or Reflect Type. These options expand its opportunities to setup and run away with the game by letting it bypass status conditions, Leech Seed, or in the latter's case, give it new resistance profiles to setup against the likes of Mega Scizor and Magearna. However, this set necessitates a lot of support, such as mandating Toxapex's Toxic Spikes to wear down Dark-types like Tyranitar, Weavile, and Ash-Greninja that it cannot hit at all. Furthermore, dropping Ice Beam leaves Mega Latias unable to perform many of the defensive duties its team appreciates, like checking Kartana and Swords Dance Gliscor.
Regular Latias may seem enticing to use its unique support movepool and good speed by running the likes of Trick, Defog, Thunder Wave, and Healing Wish, the former on a Choice Scarf set. However, this is largely outclassed by Cresselia, with possesses far superior bulk and Lunar Dance, which restores PP unlike Healing Wish.
Checks and Counters
===================
**Dark-type Wallbreakers**: Latias's weakness to Dark gives opportunities for many Dark-types, such as Hoopa-U, both Tyranitar and its mega, and Weavile. The latter three are particularly dangerous, as they often carry Pursuit, threatening to eliminate Latias outright. However, they are also hit hard by Hidden Power Fighting, and none of them particularly appreciate Thunder Wave.
**Bulky Steel-types**: Both Utility and Calm Mind Latias sets are unable to threaten the vast majority of defensive Steel-types, such as Magearna, Heatran, Ferrothorn, Mega Scizor, and Specially Defensive Excadrill. They can retaliate with the likes of Thunder Wave and Toxic, Ferrothorn's Leech Seed, or Magearna and Mega Scizor's super effective STAB moves. However, Latias can manage them with certain coverage moves on Utility sets, or leverage its immunity to Spikes to outlast them.
**Fairy-types**: Latias lacks any super effective options to hit most Fairy-types, making Clefable a safe answer to the Utility set with its good bulk and longevity, while threatening a 2HKO with Moonblast or Thunder Wave. Wallbreakers like Tapu Lele, Mega Diancie, and Mega Mawile are less resilient to Latias's attacks but threaten more damage onto it. However, none of them are particularly safe against a boosted Mega Latias, especially when chipped.
**Special Walls**: The likes of Chansey, Gastrodon, and Cresselia have the special bulk and longevity to take negligible damage from Latias's attacks, are unfazed by paralysis, and can cripple it with Toxic and Thunder Wave, or in Cresselia's case, take on Calm Mind sets with its own Calm Mind.
**Toxic and Paralysis**: Pokemon that Latias conventionally beats like Landorus-T and Toxapex often carry Toxic, completely ruining Latias's longevity. Similarly, the likes of Serperior and Rotom-W can threaten to paralyze it, leaving Latias unable to leverage its fantastic speed and being far easier to overwhelm.
