Though I tried not to get carried away, I have to mention that Mega Scizor has several effective sets that fit on most, if not all playstyles. It would definitely need an in-depth description for a solid understanding of how and why it works, hence why I took time and effort to make sure this is up to mark for anyone looking forward to a read!
Bulky SD
Scizor @ Scizorite
Ability: Technician
EVs: 248 HP / 96 Def / 164 SpD
Impish Nature
- Swords Dance
- Bullet Punch
- Knock Off / U-Turn / Superpower
- Roost
Role: Physical Sweeper, Mixed Wall, Pivot, Support (Utility Set)
What it Does:
Bulky SD Mega Scizor is an amazing Pokémon in the current Metagame due to the fact that it does its fulfills its role very well while having amazing defensive and offensive capabilities which provide it several set up opportunities against a plethora of threats such as LO Alakazam, LO Gengar, Mega Metagross, Mega Gardevoir, Mega Diancie, LO Excadrill, Weavile and Bisharp. In addition to this, Mega Scizor fits on several varied playstyles ranging from Offense, Balance and to even Semi-Stall as it provides a ton of role compresion in all the things its capable of doing.
Swords Dance is what makes Mega Scizor threatening against so many teams; Cleaning teams is easily accomplished once its checks are weakened or removed. Bullet Punch provides an excellent form of priority to sweep, kill off a weakened threat like Latios or Mega Lopunny, and deal with common set-up sweepers like Rock Polish M-Diancie and SD Weavile. Roost gives it an excellent form of reliable recovery which allows it to consistently check what its meant to.
Although SD + U-Turn may seem silly, it functions as an excellent pivot which provides your teammates free momentum, and switch initiative in order to break walls. Knock Off has amazing utility in being able of crippling common switch-ins such as Rotom-W, Heatran, and Talonflame while Superpower allows you to smack Heatran, Magnezone, and other Bulky Steels.
Good Teammates:
Scizor doesn't deal with Fire attacks or Fire types in general because of it's typing, therefore something that is capable of dealing with this is mandatory. Water types such as Keldeo, Manaphy, Rotom-W, Starmie and Suicune are capable of pivoting into and dealing with them in that regard. Bulky Fire types, mainly SpD Talon and Heatran switch-in to said Fire attacks with ease, spread status to cripple a few of Scizor's checks / counters, and fulfill mandatory roles like a Stallbreaker.
Common Waters are also capable of burning Scizor and resist its form of priority while taking minimal damage from its coverage attacks, therefore, Grass types like Serperior, Celebi, Breloom, Tangrowth, and Ferrothorn make for excellent partners, Electrics, mainly CM / Specs Raikou and Nasty Plot Thundurus pressure bulkier Water types with ease, forcing many switches and possibly stacking Hazard damage which could enforce a Mega Scizor sweep. Opposing Electric types are extremely problematic as they resist its priority, outspeed it, potentially set-up on it, and either 2HKO or OHKO. To remedy this, using Bulky Ground types like Hippowdon Gastrodon, Seismitoad, Garchomp and Landorus-T are all great options while also checking Fire types that threaten Mega Scizor.
LO Kyurem-Black specifically forms an amazing Offensive core with Mega Scizor. It functions as a Wallbreaker, mainly against bulkier playstyles like Balance and Semi-Stall that deal with Mega Scizor effectively most of the time, being capable of breaking most, if not all of the annoyances listed above and below with its excellent coverage and amazing stats. Furthermore, Mega Scizor is capable of potentially pivoting out with U-Turn or Doubling on checks such as Zapdos, Heatran, Skarmory, and TankChomp which allows Kyurem-Black to Wallbreak without taking any damage.
Latias is also another solid option to sponge Water, Electric and Fire type attacks aimed at Mega Scizor, providing Defog support, and potentially have Healing Wish support in case it gets weakened or crippled by status. On bulkier teams, Thunderbolt Latios is optional to more easily revenge TG Manaphy, DD Gyarados and BD Azumarill; Mega Scizor is also capable of checking many of the Fairies, Darks and Steels the latter cannot deal with.
In order to weaken Defensive backbones and put things in +2 Bullet Punch range, hazards are imperative alongside Mega Scizor; Possible options include Landorus-T, Hippowdon, TankChomp, Heatran as they all provide Rocks, deal with a few of the threats mentioned above, and benefit teams with all their individual attributes. As Mega Scizor avoids many 2HKO's from common wallbreakers, hazard removal is almost mandatory so it is capable of consistently checking what it is meant to on bulkier teams. Although restraining, solid options for this role include Lati@s and Starmie as they both check strong Water types, specifically Keldeo.
What Counters it:
Offensive Pokemon that resist Bullet Punch are prominent Electric types such as Thundurus, Magnezone, and Mega Manectric all heavily threaten Mega Scizor, Fire types like Charizard X/Y, Heatran, Talonflame, Victini, Entei and Volcarona are pretty self-explanatory on how they answer Mega Scizor, as they all force it out. And lastly, for Offensive checks, Water types like Starmie, Keldeo, Gyarados, and Manaphy all function as answers to Mega Scizor as they are either capable of setting up on it, crippling it with Scald burns, or simply 2HKO'ing with ease; Rain teams with abusers such as Kingdra or Ludicolo also deal with it very well as they don't allow it to set-up by hitting it with either Hydro Pump or Scald.
Finally, finishing up with Counters, Physically Defensive walls such as Zapdos, Skarmory, Mandibuzz, Rotom-H, TankChomp, Mega Venusaur, Mega Sableye, and Rotom-W all counter Mega Scizor. Zapdos and Rotom-H are hard counters as they both have recovery, amazing defensive typing against M-Scizor with access to Heat Wave and Overheat respectively. Counter Skarmory wins in most if not all 1v1 situations, Mandibuzz and Mega Sableye beat it as they prevent it from setting up with Foul Play while taking nothing from Bullet Punch.
TankChomp is a counter to this set as it whittles it severely with recoil damage and can deal a lot of damage with Fire Blast, or phaze it out with Dragon Tail. Mega Venusaur outspeeds and can force Mega Scizor out with HP Fire, while Rotom-W is also a counter to the Bulky SD set in particular as it capable of crippling it with Will-O-Wisp and pivoting out to something else or weakening it with Hydro Pump.
Any Additional Info:
Thanks to Mega Scizor's natural bulk and that specific EV spread, it can avoid 2HKO's from a plethora of threats such as LO / Mega Alakazam, LO Gengar, Mega Metagross, LO Mamoswine, LO Excadrill, Band Azumarill, Mega Lopunny, Bisharp, Mega Gardevoir, and Kyurem-Black which are often used early-mid game to pressure teams. It should not trying sweeping until its checks and counters listed above are either majorly weakened or removed, but that rule typically goes for any set-up sweeper.
You should try to keep up as much momentum as possible so it doesn't get overwhelmed or too pressured by hazards + pivots, making it unable of checking what its supposed to. Keep in mind that Mega Scizor gets pressured by multiple layers of hazards because it comes in as a pivot a lot, so it will eventually get broken if you don't have hazard removal or Healing Wish support; It’s important to keep itself healthy with Roost in order not to get overwhelmed.
Another option you have is a set of Bullet Punch / U-Turn / Roost / Pursuit which functions as an amazing pivot and trapper against mons such as Gengar and Lati@s, or by keeping up momentum with U-Turn. Although you would lose a lot of Offensive presence with the lack of Swords Dance, it's an excellent Utility set that should be used on more Defensive playstyles.
Lastly, be wary for lures that are currently picking up in usage like Will-O-Wisp Mega Gardevoir, Fire Punch Hoopa-U and HP Fire Kyurem-Black, Lati@s, Mega Diancie as they can simply break Mega Scizor, allowing them to heavily weaken or simply get a kill each time they come in if its caught by said moves.
Offensive SD
Scizor @ Scizorite
Ability: Technician
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
- Swords Dance
- Bug Bite
- Bullet Punch
- Superpower
Role: Physical Sweeper
What it Does:
Offensive SD Mega Scizor is an extremely potent sweeper in the current metagame, typically found on more Offensively inclined playstyles. It can do a two things, one, during early game it can play as a fairy Fairies and Dragon check and act as a breaker, and or be brought out mid-late game once its checks and counters are weakened or eliminated or locate a set-up opportunity to plough through your opponent's team.
Adamant is used over Jolly for its raw power, allowing it to OHKO and or 2HKO its checks once in range but if preferred, Jolly is optional for outpacing Heatran that specifically creep the Adamant version in addition to outspeeding Jolly Breloom, Bisharp and Adamant Diggersby.
Bug Bite is used to break down common Defensive Water types like Rotom-W and Suicune which would trouble it otherwise. Having a form of priority on slower sweepers such as Mega Scizor or Azumarill is really nice because it allows you to pick off weakened threats and sweep without taking damage, making Bullet Punch an excellent choice. Superpower is used in the last slot to break Steel types that it would otherwise struggle with such as Skarmory, Heatran and Magnezone. Even with no investment in bulk, its Defensive stats alone allow it to set-up safely on Offensive Fairy types and Dragons lacking fire coverage.
Good Teammates:
Offensive SD Mega Scizor greatly appreciates hazard support to ensure certain 1HKO's or 2HKO's after a single Swords Dance, but they are also valued alongside Scizor to weaken its checks steadily throughout the match which may allow it to sweep easier. Heatran, Landorus-T, and TankChomp are solid examples of Rock setters but they all have their individual advantages as well. For example, Heatran and Garchomp both provide a solid counterplay against Talonflame whereas Swords Dance + Stealth Rock Landorus-T can provide a SR setter which also pressures Bulkier Playstyles, opening up a situation for Mega Scizor and common teammates to have an easier time developing a win condition.
As Fire types give it trouble, something to break them like Specs Keldeo, LO Starmie, TG Manaphy, or Azumarill would be appreciated, but a better check to Offensive Electrics such as Latias would be needed. Speaking of Latias, it makes an excellent partner for Offensive SD Mega Scizor as it provides Healing Wish and Defog support. Due to the fact that Scizor gets worn down and is prone to status like any other Pokémon while attempting a sweep, Healing Wish would provide it a second chance at cleaning which keeps up momentum on Offense as well.
Not only this, but Latias checks all the Offensive Electrics that Scizor typically struggles with, but not having Recover means a secondary way of counterplay would be appreciated. To remove or weaken Bulky Waters that may prevent it to sweep, Electric types such as Thundurus or Raikou, or wallbreakers like Lati@s, Serperior, Kyurem-Black, and Hoopa-U can be used effectively.
Pokémon that share similar checks to Mega Scizor can be ran alongside it to pressure and overwhelm them for a possible late game sweep; Some examples of this are: SD Landorus-T, SD Garchomp, SD Bisharp, SD Talonflame and Band Azumarill. Despite sharing weaknesses, LO Taunt Tornadus-T pairs with Mega Scizor very well as Knock Off capable of crippling down checks with Leftovers, provides momentum with U-Turn, and prevents recovery with Taunt which breaks fatter Playstyles well along with a powerful Hurricane that dents both of their checks, especially with Stealth Rock up.
What Counters it:
Offensive Pokemon that resist Bullet Punch like prominent Electric types such as Thundurus, Mega Manectric, Magnezone, and Raikou all heavily threaten Mega Scizor, Fire types like Charizard X, Victini, Speedy Heatran, Entei, Talonflame, Charizard Y, and Volcarona are pretty self-explanatory on how they answer Mega Scizor, as they all force it out. And lastly, for Offensive checks, Water types like Keldeo, Gyarados, Starmie, and Manaphy all function as answers to Mega Scizor as they are either capable using it as set-up fodder, crippling it with Scald burns, or simply 2HKO'ing with ease; Rain teams also deal with it very well as they don't allow it to set-up by hitting it with either Hydro Pump or Scald.
As a quick mention, you've probably noticed a commodity in answers cause, well, it is the same Pokémon with a slight alteration of a set. The only real changes between the variations of the checks and counters section is Offensive SD Mega Scizor being able to more easily pressure its checks and counters alike with Stealth Rock in particular and +2 BP, Bug Bite and or Superpower depending on whether said Pokémon is an offensive or defensive check, whereas Bulky SD Mega Scizor has more staying power with Roost and knock off alongside its bulk to abuse the threats it walls as set-up bait. This means that its counters will be lacking.
Going deeper on about pressuring its Checks and Counters, Raikou, Mega Manectric, Charizard-Y, SpD Talonflame, Bulkier Heatran, Manaphy, Mega Sableye, TankChomp and several otherwise "checks" fall pressure to the strength of Offensive SD Mega Scizor thanks to either Stealth Rock and +2 BP, +2 Bug Bite and or Superpower. For example, you set rocks to pressure its Offensive and Defensive checks alike, forcing switches until the said check, lets say, Mega Manectric or Zard-Y gets in range of +2 BP. With defensive checks, the only way M-Sable can beat it is if its pre-mega, otherwise it simply gets OHKO'd by +2 Bug Bite, along with TankChomp getting extremely weakened, opening up another chance for a cleaner to finish up the game.
Continuing onwards, There are Pokemon capable of reliably countering this set like Zapdos, Quagsire, Rotom-H, Counter Skarmory and Mandibuzz as they all have ways to beat it in any given situation. Zapdos easily lives a boosted Bug Bite and retaliates back with Heat Wave while having reliable recovery, Quagsire has the ability Unaware which means it ignores all of Mega Scizor's boosts and can cripple it with Scald burns, Rotom-H can either Burn Scizor with Will-o-Wisp or OHKO it with Overheat; It has a form of recovery in Pain Split to stay healthy until late game where it will typically attempt to sweep, Skarmory has access to Counter as well as the Sturdy ability which allows it to live any hit coming from Mega Scizor. Finishing off, while Stealth Rock weak and slower, Foul Play OHKO's +2 Mega Scizor and lives a +2 Bug Bite after Stealth Rock.
Any Additional Info:
Another way of dealing with this specific set is with Passive Damage and or Offensive pressure due to its lack of recovery. When using this specific set of Mega Scizor, try to apply as much Offensive pressure as possible with Wallbreakers + Hazards when going for a late game Mega Scizor sweep so its checks and counters get overwhelmed and pressured, while opening another set up opportunity for a teammate now that its checks are in range.. In addition to this, do not let it get weakened by switching a ton into resisted hits as it weakens its chances of pulling off a sweep or weakening a wall for another Pokémon to sweep.
AM Edit: damn
