Mega Pinsir is one of the biggest offensive threats to the team. At +2, every member of the team is OHKO'd by either Return, Close Combat or Quick Attack. Mega Pinsir can take a hit from every member of the team bar Heatran, but if it wants to sweep it is best to set up against Gliscor, as it doesn't have to fear the Leech Seed (which can be annoying with CC / Return mindgames) from Ferrothorn, Scald burns from Keldeo / Slowbro or Psychic from Mega Alakazam. Against Gliscor, Mega Pinsir can even set up after taking 50% Stealth Rock damage, as Knock Off doesn't even 6hko MPinsir.
The easiest way of getting a sweep against the team is to lure in Gliscor and set up with Mega Pinsir. A few pokemon that can lure in SpD Gliscor are Alakazam, Gengar, Heatran, Reuniclus, Clefable and Tyranitar. Reuniclus and Clefable stood out because they can both act as a secondary win condition. I think Clefable is a better teammate for Mega Pinsir than Reuniclus, because it is able to check pokemon like Weavile, Mega Manectric and Kyurem-B, who can all give MPinsir troubles. Heatran is used without Taunt or Roar, so Clefable can use it as setup fodder. CM Slowbro and Ferrothorn are the main switchins for Clefable in this team, but Thunderbolt will force out Slowbro and Ferrothorn gives Mega Pinsir a free Swords Dance if it gets a free switch in. While Ferrothorn can still hit MPinsir hard with Gyro Ball on the switch in, and Gliscor can Taunt MPinsir on the switch in, offensive pressure by other teammates and smart double switches (after revealing Thunderbolt) will give Mega Pinsir a free switchin which will (most of the time) result in a win.
TBolt Clef + Mega Pinsir is a great core in general because Clefable checks both offensive (manec, raikou, aero) and defensive counters (hippow, mandi, rotomw) of Mega Pinsir. With Thunderbolt, Clefable lures in 3 of the most common Mega Pinsir checks / counters in Talonflame, Skarmory and CM (Mega) Slowbro.
