Mega Rayquaza's excellent mixed offenses and STAB on the type with the best neutral coverage in the game allow it to utilize a variety of sets effectively. The most common Mega Rayquaza sets utilize powerful priority attacks with the ability Aerilate to boost priority moves' power or the ability Gale Wings to increase its Flying-type moves' priority, making Mega Rayquaza an excellent revenge killer; additionally, Mega Rayquaza can also work well as a wallbreaker or setup sweeper, and can use less common but still effective sets such as mixed Protean or Contrary to surprise common walls and sweep. However, Mega Rayquaza is commonly walled by nearly anything that its Flying-type STAB is not very effective against and is commonly accounted for during teambuilding, although common walls may be countered with certain coverage moves. Mega Rayquaza also lacks a reliable way to keep healthy throughout the match, as well as being a common target for Imposters. Regardless, Mega Rayquaza should be considered for any hyper offensive or balanced team due to its versatility and ability to perform several roles effectively.
name: Standard Aerilate
move 1: Fake Out / King's Shield
move 2: Extreme Speed
move 3: Boomburst / Techno Blast
move 4: Spore / King's Shield / Magma Storm
item: Safety Goggles / Sky Plate
evs: 252 Atk / 4 SpA / 252 Spe
The high priority of Fake Out and Extreme Speed, coupled with Extreme Speed's decent power, allows Mega Rayquaza to almost always hit hard before the opponent moves. Fake Out, which is boosted by Aerilate and STAB, gets free damage due to the 100% flinch chance and can be followed up by Extreme Speed to deal good damage to anything that does not resist it. However, King's Shield can replace Fake Out to scout the opponent's moves and punish Pokemon using contact moves. Mega Rayquaza's third move slot is Boomburst, which 2HKOes practically anything that does not resist it and hits through Substitute, although it is blocked by Soundproof. If Soundproof is a worry, Techno Blast can be used instead, but Techno Blast has fewer PP and less power and doesn't bypass Substitutes. For Mega Rayquaza's final moveslot, King's Shield may be used to prevent revenge killers from KOing it and to scout the opponent's moveset; however, be wary when using King's Shield, as it does not protect from status moves. Alternatively, Magma Storm can be used to hit Steel-types super effectively while also KOing Sturdy Shedinja on the switch. Spore can also be used to put a foe to sleep. However, this makes Mega Rayquaza susceptible to Magic Bounce users; Safety Goggles may be used to overcome this drawback.
Mega Rayquaza has maximum EVs in Attack and Speed to outspeed or Speed tie with other Mega Rayquaza and maximum Speed Mega Diancie while also dealing maximum damage with Fake Out and Extreme Speed. The final 4 EVs are invested into Special Attack to deal slightly more damage with Boomburst. A Hasty Nature allows Mega Rayquaza the most offensive capability with maximum Speed. Mega Rayquaza may also alter its EVs to favor Special Attack, changing its role from a priority-using revenge killer into a wallbreaker. Aerilate, which turns Mega Rayquaza's Normal-type moves into boosted Flying-type STAB moves, is the chosen ability to provide powerful Flying-type priority attacks. Sky Plate can be used to boost all of Mega Rayquaza's STAB attacks without any drawbacks. Safety Goggles is another option to avoid being hit by Spore, which is commonly found on a Prankster Steel-types. Safety Goggles also complements Mega Rayquaza's own Spore, as it prevents Mega Rayquaza from being put to sleep if it uses Spore on a Pokemon with Magic Bounce.
Mega Rayquaza should use Fake Out and Extreme Speed if the foe can outspeed or outprioritize it otherwise, while Boomburst is the preferred option for wallbreaking against slower teams. However, due to the abundance of King's Shield in the metagame, Boomburst can be used over Fake Out or Extreme Speed if the foe is suspected to have King's Shield. Moves such as U-turn, Volt Switch, Baton Pass, and Parting Shot are useful for bringing in Mega Rayquaza safely, as it is relatively frail and does not appreciate taking unnecessary damage.
As Mega Rayquaza is weak to other common Fake Out and Extreme Speed users such as Kyurem-B and Mega Diancie, a Steel-type such as Registeel or Aegislash that resists both of these Pokemon's STAB moves is a vital teammate. These two Steel-types can also counter to Pokemon with Imposter that have transformed into Mega Rayquaza. A way to beat Shedinja is necessary, as Mega Rayquaza cannot break Shedinja unless it has Magma Storm, which is unreliable. Effective ways to deal with it are entry hazard support and Pokemon with a combination of Mold Breaker and Pursuit. Mega Rayquaza also appreciates hazard removal and cleric support through Pokemon such as Mega Audino and Registeel, as Mega Rayquaza is weak to Stealth Rock and is crippled by burns, which makes its priority attacks nearly useless. Mega Rayquaza also appreciates hazard setters such as Giratina and Deoxys-S, as Mega Rayquaza usually forces a lot of switches. Pokemon that can remove Steel-types, such as Protean Mega Mewtwo X and Earth Plate + Judgment users such as Mega Mewtwo Y are also necessary to eliminate some of Mega Rayquaza's most common checks.
name: Special Gale Wings
move 1: Oblivion Wing
move 2: Substitute
move 3: Tail Glow
move 4: Magma Storm / Earth Power
item: Life Orb / Leftovers
ability: Gale Wings
evs: 252 SpA / 4 SpD / 252 Spe
Oblivion Wing is a strong Flying-type move that recovers Mega Rayquaza's HP, allowing Mega Rayquaza to run a Life Orb to compensate for the loss of power compared to Boomburst. It also allows Mega Rayquaza to effectively use Substitute to block incoming status and attempted use of Imposter, as the HP lost from using Substitute can be regained through Oblivion Wing. Tail Glow boosts Mega Rayquaza's Special Attack to drastic levels, allowing it to take down even some Pokemon that resist its attacks; with a Substitute and a single Tail Glow, Mega Rayquaza can OHKO Mega Diancie without fear of being knocked out by Extreme Speed or Fake Out. Magma Storm can be used to hit Steel-types that resist Oblivion Wing. Magma Storm can also KO Shedinja. Alternatively, Earth Power can be used to hit Steel- and Rock-types, both of which resist Oblivion Wing. However, Mega Rayquaza is unable to hit Shedinja with Earth Power and therefore requires the team to have another way of beating it.
Gale Wings gives all of Mega Rayquaza's Flying-type moves +1 priority, allowing it to outprioritize most threats other than Fake Out and Extreme Speed users. Life Orb is used to increase the power of Oblivion Wing. Oblivion Wing restores HP, and counteracts the recoil from Life Orb. Alternatively, Leftovers can be used to allow Mega Rayquaza to set up more Substitutes. Maximum Special Attack and Speed investment allows Mega Rayquaza to hit as hard and as fast as possible. Modest is preferred to maximize Special Attack, but Timid can be used to outspeed other Gale Wings Mega Rayquaza.
Try to bring in Mega Rayquaza on something it can force out in order to set up Substitute or Tail Glow. Be wary setting up when the opponent still has a Pokemon with higher-priority moves or a tank that resists Oblivion Wing, as these can often force Mega Rayquaza out. Due to Substitute blocking Transform and Imposter, Substitute is generally the best choice if the opponent still has an Imposter in the back. Only attempt to sweep when anything that can check Mega Rayquaza at +3 Special Attack has been removed.
Imposter Chansey is a common switch-in to Mega Rayquaza. Therefore, a powerful special tank or an Unaware user such as Cresselia is vital to prevent it from sweeping. If Earth Power is used over Magma Storm, Shedinja is another option to take on Chansey as well as to beat Mega Diancie. This set appreciates entry hazard removal from Pokemon like Registeel and Giratina to avoid taking unnecessary amounts of damage from switching in. Mega Rayquaza also appreciates having hazards on the opponent's side of the field through Pokemon such as Giratina and Deoxys-S, as entry hazards prevent Shedinja from switching in. Steel-type tanks such as Registeel and Aegislash are useful to take attacks from Pokemon with the abilities Pixilate and Refrigerate using Fake Out and Extreme Speed. Shedinja should still be accounted for, even if Magma Storm is run, and can be checked by a Mold Breaker Pursuit user or the aforementioned hazards. This Mega Rayquaza set is not threatened as much by status, as Substitute blocks most of it, but because it tends to stay in for extended periods of time, status removal through Pokemon like Mega Audino is useful to keep Mega Rayquaza healthy.
Physical Gale Wings Mega Rayquaza with Dragon Ascent is another option that does not take up your -ate slot and can still do massive damage with a priority STAB move. Another possible option is Contrary Mega Rayquaza, which has the opportunity to surprise its common checks and counters with moves like V-Create, Overheat, and Leaf Storm. However, it still struggles against Chansey and Shedinja; with a Choice Scarf, Mega Rayquaza may be able to handle Chansey but only if predicted correctly. Mega Rayquaza can also run mixed Protean sets due to its excellent mixed offenses in order to surprise switch-ins to its Aerilate or Gale Wings sets. Mega Rayquaza also has several other options for its Aerilate set. One possible option is swapping the Attack and Special Attack EVs for more power in Boomburst, although this weakens the power of Fake Out and Extreme Speed. Mega Rayquaza may also change its fourth moveslot to Infestation to consistently beat Shedinja, or Precipice Blades, Low Kick, or Thousand Arrows to hit common switch-ins to Mega Rayquaza super effectively, although an Imposter counter must be chosen appropriately. Finally, Mega Rayquaza may run Choice Scarf with Aerilate to have a fast Boomburst. If this is run, Trick is an excellent option to cripple switch-ins. Pivot moves such as Volt Switch are also excellent choices, as Mega Rayquaza does not mind the Choice item when using those.
Checks and Counters
**Mega Diancie**: Mega Diancie is a significant threat to Mega Rayquaza, as Mega Diancie resists both of Mega Rayquaza's STAB moves and can threaten it with a super effective Pixilate Extreme Speed.
**Physically Bulky Soundproof Pokemon**: Physically bulky Soundproof users such as Mega Slowbro and Arceus can tank Aerilate Mega Rayquaza's Fake Out and Extreme Speed and are not affected by Boomburst.
**Registeel and Aegislash**: With a resistance to Flying, Steel-type tanks can switch into any attack and may not even be KOed by coverage moves. Additionally, sets running Levitate, Flash Fire, and Prankster may counter any one variant of Mega Rayquaza.
**Shedinja**: If Mega Rayquaza lacks a way to beat Shedinja, Shedinja can consistently switch in to take in Mega Rayquaza's attacks and threaten to use Endeavor or gain momentum by pivoting into another Pokemon.
**Protean + King's Shield**: Pokemon with Protean and King's Shield such as Mega Mewtwo X and Mega Mewtwo Y can use King's Shield to harshly lower Mega Rayquaza's Attack upon contact and change their typing to Steel, which resists Mega Rayquaza's STAB types.
