Moves
Hurricane is Noctowl's STAB move of choice despite its low accuracy because of its high Base Power and ability to deal neutral damage to most targets courtesy of Tinted Lens while also OHKOing Victreebel after Stealth Rock. Roost keeps Noctowl healthy and provides additional chances to sweep or wallbreak. Roost also compensates for Noctowl's weakness to Stealth Rock and can be used to sponge Volt Switch from slow users such as Lanturn.
Set Details
A Modest nature is preferred so that Noctowl can function primarily as a wallbreaker and OHKO Assault Vest Hitmonchan and Skuntank unboosted; it's still faster than threats such as Choice Scarf Primeape after Agility. A Timid nature lets Noctowl naturally outspeed neutral-natured base 80 Speed Pokemon like Shiftry, but this forfeits a considerable amount of Noctowl's attacking power. Tinted Lens is a crucial ability, as it lets Hurricane hit the likes of Aurorus and Regirock neutrally. Flyinium Z gives Noctowl a one-time nuke that, alongside setup, is capable of demolishing specially bulky Pokemon like Lanturn and Eelektross. Its perfect accuracy is also helpful in dire situations where Noctowl needs to land an attack. Sky Plate is a viable alternative if another teammate is using a Z-Crystal, giving Noctowl more consistent damage output. However, Noctowl sorely misses out on the power brought by using Flyinium Z, which includes OHKOing Pokemon like Eviolite Scyther and Oricorio-E after Stealth Rock without a boost.
Usage Tips
Noctowl functions best utilizing Work Up, Tinted Lens, and Hurricane to break through balance and bulky offense teams that rely on Pokemon like Regirock, Oricorio-E, and Lanturn to take Flying-type attacks. Assess whether Agility or Work Up is more important to set up first. Against offensive teams, Agility gives Noctowl an edge over fast Pokemon that would otherwise threaten it like Alolan Sandslash and Jynx. Work Up functions well versus bulkier teams, allowing Noctowl to punch through walls after a sufficient number of uses. For instance, +1 Supersonic Skystrike can OHKO Aurorus and Regirock after Stealth Rock damage, whereas an unboosted Supersonic Skystrike or a boosted Hurricane can OHKO Alolan Sandslash and Kabutops. Supersonic Skystrike can also be used if Noctowl can't afford to miss Hurricane, such as against a Pokemon like Aggron, which threatens to decimate Noctowl in return. It's also useful for securing an OHKO on Pokemon like Carracosta and Omastar, where Noctowl can't afford to set up at all. In spite of great special bulk, Noctowl should not be used as a sponge to special attacks; instead, bring it in safely through pivoting moves like Volt Switch and Parting Shot. However, Noctowl can switch into weaker users of Knock Off such as Tangela and Sableye to preserve its teammates' items and threaten both examples with Supersonic Skystrike. A weakness to Stealth Rock and susceptibility to residual damage is often a liability for Noctowl, so keeping it healthy increases its chances of being able to successfully set up versus weaker special attackers such as Bellossom. Use Roost to heal when against Pokemon that can't do much harm to Noctowl, such as Audino, but be wary of the occasional Toxic. Status from users like Toxic Poliwrath and Thunder Wave Qwilfish is something Noctowl should try to avoid in general. Use advantageous matchups as setup time, as this is the key to Noctowl's success. Choice item users such as Haunter can be taken advantage of, depending on what they're locked into. Some Pokemon that can't do much to Noctowl include Lurantis and Bellossom. Finally, Noctowl can engage in mind games with other Pokemon like Hitmonchan and Abomasnow, which are naturally threatened out by Supersonic Skystrike.
Team Options
Wallbreakers such as Drampa and Aggron can weaken defensive Pokemon like Audino and Clefairy, paving the way for Noctowl to sweep using Agility. Similarly, late-game cleaners such as Jynx, Carracosta, and Primeape appreciate Noctowl's ability to weaken bulky Pokemon such as Poliwrath and Gurdurr. Blanket checks to physical attackers such as Regirock, defensive Carracosta, and Gurdurr take powerful physical hits for Noctowl, while it can check Grass-types like Bellossom and Lurantis in return. Noctowl thrives on getting free switches to start setting up, so slow pivots like Probopass and Eelektross can help. Conversely, Silvally-Dragon operates well as a fast pivot thanks to Parting Shot lowering the foe's offensive stats, giving Noctowl an easier shot at setting up. Silvally-Dragon's ability to unleash a powerful Draco Meteor and target Steel-types like Ferroseed with Flamethrower can help secure a potential sweep for Noctowl. Entry hazard removers such as Hitmonchan and Skuntank are essential, as Noctowl is weak to Stealth Rock. Hitmonchan also works as an offensive check to Pokemon like Ferroseed and Aggron while appreciating Noctowl's ability to break threats such as Tangela, whereas specially offensive Skuntank can soften special walls with Acid Spray. Skuntank also enjoys Noctowl being able to switch into Ground-type attacks. Noctowl appreciates entry hazards from Pokemon like Qwilfish weakening switch-ins. A notable feat that Noctowl can pull off with Stealth Rock is OHKOing Regirock with +1 Supersonic Skystrike. Qwilfish can weaken physical attackers with Intimidate and soften targets with Explosion. Clefairy also appreciates Noctowl being able to power through Steel-types like Aggron and Metang with Supersonic Skystrike and absorb Knock Off from weaker users like Audino.
