This is a mega Pinsir team that I had help tweaking so let me know if u catch something else.
Pinsir-Mega @ Pinsirite
Ability: Hyper Cutter
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Close Combat
- Quick Attack
- Return
- Swords Dance
Mega Pinsir is the star of the team with a high base attack stat of 155 and a moderate base speed at 105 along with set up capabilities and a STAB priority move thanks to Aerilate Mega Pinsir can OHKO almost anything that's slower than it as well as getting off a lot of damage on things faster with Quick attack.
Magnezone @ Choice Specs
Ability: Magnet Pull
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk / 30 SpA / 30 Spe
- Hidden Power [Fire]
- Flash Cannon
- Thunderbolt
- Volt Switch
The first thing about Mega Pinsir is its glaring weakness to skarmory so we have a nice Specs Magnezone to 2 hit KO skarmory as well as other steel types such as non superpower Scizor and an already choiced Jirachi.
Landorus-Therian @ Rocky Helmet
Ability: Intimidate
EVs: 252 HP / 164 Def / 92 Spe
Impish Nature
- Stealth Rock
- Earthquake
- Stone Edge
- U-turn
Landorus is the physical wall because of threats like talonflame that out prioritize and out speed Magnezone and mega Pinsir. This also helps give momentum and to set up rocks to help with Mega Pinsir sweeping.
Latias @ Leftovers
Ability: Levitate
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Defog
- Healing Wish
- Draco Meteor
- Psyshock
Latias is the first for, of hazard control as well as another hard hitting special attacker with good bulk. Defog is to clear away rocks and other hazards that hinder mega Pinsir. Healing wish is to provide a win con another life if it gets too low. Draco and psyshock are Latias' two main forms of STAB attacks and hits hard.
Excadrill @ Choice Scarf
Ability: Mold Breaker
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Earthquake
- Iron Head
- Rapid Spin
- Rock Slide
Next we have a scarf excadrill. Scarf Excadrill is here to provide a check to mega diancie which is a big threat to the team as well as more speed control, and rapid spin to remove hazards if we want/ need to keep ours up. EQ and Iron Head are Exca's main STAB moves and rockslide for coverage and to provide a check for non focus blast thunderous.
Starmie @ Life Orb
Ability: Natural Cure
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Scald
- Ice Beam
- Rapid Spin
- Recover
And lastly starmie. Starmie serves as a non scarfed answer to mega diancie as well as serving as another rapid spinner scald is a guaranteed OHKO on mega diancie as well as a 30% chance to burn. Ice beam for coverage and recover to help with Starmie's sustainability with the life orb for added damage.
So that's the team let me know if u have any suggestions/ improvements :)
