Sharing another core, this one being one I recently made for an offensive team.
Offensive Core
Scolipede + Mega Aerodactyl
This is a core of two super fast physical attackers that have great offensive and even defensive synergy. They do a pretty efficient job at wearing down each other's checks, Scoli taking care of the likes of Slowbro, Clefable, Mega Altaria, Azumarill Mega Sableye and co. while Mega Aerodactyl beats up Talonflame, Torn-T, Zapdos, Gengar, Lando-T and Scizor (with Fire Fang on the switch) for Scoli. Some Pokemon like Megagross and Ferrothorn can check one Pokemon temporarily, but cannot live one hit after the other from the duo, allowing one to succeed in cleaning if the other falls. The core's speed is also very important, making it tough for opposing offense to get hits in the majority of the time, outside of priority, Sand Rush Excadrill, Swift Swimmers, and MegaZam and select Scarfers in Aero's case.

Threats
- Skarmory - Neither can 2HKO physically defensive Skamory, the Mega Aero has a chance to do so with Fire Fang after SR damage.
- (Mega) Scizor - While Mega Aerodactyl has Fire Fang for it, it fairs poorly in 1 v 1 since Choice Band and Life Orb Bullet Punch OHKO and Offensive SD Bullet Punch also has a chance of doing so. Furthermore, bulky Mega Scizor sets can live a Fire Fang and OHKO if Aerodactyl has taken SR damage. Scolipede does little to defensive variants and takes a lot from Bullet Punch on offensive ones.
- Bulky Waters - While not too many threaten the core, CM Manpaphy and Suicune can prove troublesome for the core in particular.
- Heatran provides Rocks support and helps with steels that give the core trouble. Magnezone also fits like a glove, dispatching Steels and bulky Waters and covering weaknesses to Rock, Ice, Flying and Electric that Scolipede and/or Aerodactyl have. Hazard control is important, making the Lati twins, Mew, Excadrill, Starmie and Zapdos good choices.
