Explanation

M.Scizor
I wanted to use offensive M.Scizor as Bullet Punch seriously dents opponents from Scizor whilst still retaining bulk and decent speed.
Bullet Punch, Bug Bite and Swords Dance are staples but the last move I wanted to hit some of M.Scizors checks. These were Toxapex, Rotom-W and Landorus-T. A move to fit all this criterea was Double Edge an old move only available through Gen1.

+2 252+ Atk Scizor-Mega Double-Edge vs. 252 HP / 232+ Def Toxapex: 173-204 (56.9 - 67.1%) -- guaranteed 2HKO after Stealth Rock and Black Sludge recovery

252+ Atk Scizor-Mega Double-Edge vs. 252 HP / 232+ Def Toxapex: 87-103 (28.6 - 33.8%) -- 97.2% chance to 4HKO after Black Sludge recovery

57+28.6+12.5 from rocks results in 98.1, a very good chance to 2hko after an sd on switch, a boosted Double Edge and and a non boosted Double Edge from haze/burn from Scald.


+2 252+ Atk Scizor-Mega Double-Edge vs. 248 HP / 240+ Def Rotom-Wash: 221-260 (72.9 - 85.8%) -- guaranteed 2HKO after Leftovers recovery
Double Edge also does a sizable chunck to rotom-w, so with waring down, you can catch rotom-w of guard.

+1 252+ Atk Scizor-Mega Double-Edge vs. 252 HP / 216+ Def Landorus-Therian: 190-224 (49.7 - 58.6%) -- 99.6% chance to 2HKO
2hkoing Landorus-T whilst Lando can only 3hko back is amazing for M.Scizor allowing it to set up more easily.


Garchomp
With M.Scizor being weak to fire types fast and slow, I wanted a good way to pressure them, and revenge kill them, and what better mon could fill this role than Garchomp, resisting attacks, and even outpacing +1 Volcarona and Charizard X/Y. Outrage can also work as a late game cleaner, with M.Scizor complimenting it by helping to remove fairies.

Greninja-Ash
Lastly for the offence, I wanted a breaker and offensive pivot and I felt Greninja-Ash fit this role well, as it force switches as well as having powerful attacks to fire off in Dark Pulse and Hydro Pump. Also having secondary priority on the team is nice to help deal with fast threats getting out of hand.

Magnezone
I wanted Magnezone on the team as I was not using Superpower to break through steel types, yet I also wanted a bulky steel type/electric check, so I decided to condense the two with a bulky AV set, only really trapping Skarmory and Ferrothorn with the speed investment outpacing 8 speed Skarmory. The rest went into bulk allowing Magenzone to come in multiple times on threats like Koko and Lele. Magnezone also connects up with Greninja to complete a Volt Turn core, bringing in offensive threats with minimal damage taken to them.

252 SpA Tapu Lele Hidden Power Fire vs. 252 HP / 164+ SpD Assault Vest Magnezone: 74-88 (21.5 - 25.5%) -- 0.5% chance to 4HKO

252 SpA Magnet Tapu Koko Thunderbolt vs. 252 HP / 164+ SpD Assault Vest Magnezone in Electric Terrain: 59-70 (17.1 - 20.3%) -- possible 5HKO

0 SpA Zapdos Heat Wave vs. 252 HP / 164+ SpD Assault Vest Magnezone: 92-110 (26.7 - 31.9%) -- guaranteed 4HKO

Landorus-Therain
Next I needed rocks and a check to the meta, and what better than Landorus-T, also further complimenting the Volt Turn Core. Rocks are extremely important to M.Scizor as it helps late game cleaning and helps it beat Toxapex. Knock Off is used to weaken Chansey with removal of eviolite and more importantly, remove potential shed shell on Skarmory, improving stall match up greatly. HP Ice can also be run in this slot as a check to many of the tiers threats and weaken opposing Landos to reduce recoil taken on M.Scizor. 24 spdef allows Landorus-T to live a life orb Hp Ice from Tapu Koko at full, and the speed are to outpace the 68 speed Finis which have speed crept the current standard Landorus Set.

Tapu Fini
Lastly a Defoger was needed, a checks to Greninja-Ash and a more defensive fire switch in, and Fini fit the role nicely, as taunt can help break stall, and Nature's Madness weaken mons to put into range of +2 Bp. Finis type can allowing it to come in on mons threatening Landorus-T, Garchomp and Magnezone too, being a nice compliment too the team. The Speed evs allow it to out pace 16 speed Landorus-T, the current standard set and then the rest goes into mixed bulk, with hp hitting a lefties number +1, for maximum recovery with not taken too much from poison or rocks damage.
