Hi, this is JadeX92.
Erm, I don't really know how to start writing the post so I guess I'll just go right straight into the team building process.
ABSOL @ Absolite
The reason why I choose to start of with Absol as the centre of my team building is because I need a Mega who can take Knock Off. There's really a high increment in opponent running Knock off in their Pokemon and what's worst, the damage input for Knock Off is rather threatening too. Thus, I need a Pokemon who can absorb Knock Off and with Absol's Justified. It can up it's attack to a dangerous level. Magic Bounce is also one good ability which deflects status + rocks/spikes/seed.

Sucker Punch
Superpower
Knock Off
Knock Off is Absol's standard attack. Mega Absol is fast enough so I don't really use Sucker Punch that efficiently as I initially thought I would. Play Rough and SuperPower are there just for Coverage. I used to run a Naive natured Absol with Fire Blast to handle mainly steels, Thunder Wave to cripple or Sword Dance to boost its offense. Ended up deciding to change the last moveslot to Superpower to handle Steel. (Since I have Heatran for Fire and Whimiscott for Cripple)
Whimsicott @ Leftover
Whimsicott was chosen to complement Absol's Weakness, To combat Fighting moves. Whimsicott may be a low-tier Pokemon but it was one of my MVP in the team! First, it acts as a shield towards Lati@s Draco Meteor. Secondly, it's a great switch in against Rotom-Wash and many popular Hydro Pumps in the metagame. In short, my defense for the team.

Knock Off
With Whimsicott around, it breaks set-up Pokemon. Crippling non-grass and electric Pokemon with Stun Spore. And spam Leech Seeds around. Knock Off is there just to cause more annoyance. It used to run Moonblast which I find it rather power-lackluster. Memento doesn't do well for my team as I don't run any set up Pokemon. Grass Whistle was good except for its low accuracy plus. Also, I don't feel good not running any offense move on a Pokemon.
Heatran @ Leftover
Since I already have Whimsicott, I won't be running Ferrothorn as my Rock Setter. Thus, Heatran is chosen to form a defensive duo core with Whimsicott as they are both able to take each other's weakness.

Stealth Rock
Lava Plume
Roar
Wil-O-Wisp
Having the same defensive role as Whimsicott, Heatran's role was mainly to spread Wil-O-Wisp to further improve the defense of the team since Mega Absol is really frail. Lava Plume is there for STAB and occasionally lucky burnt on the opponent's Pokemon. Heatran used to run protect which works extremely well til I met Suicune who managed to set up on my Heatran without me being able to do anything. Thus decides to run Roar instead. Still finds Protect better on my Heatran somehow :/
Landorus-T @ Choice Scarf
I used to run a Mega Manetric Team with Landorus for Duo Intimidate with a Ferrothorn Wall. Was really tempted to use Landorus as a rock setter, but I really dislike stall battle and I need a Pokemon to be able to pivot well. Probably a fast bulky U-turn or Volt switcher. Landorus-T was thus chosen in place of Scarf Rotom due to intimidate and more offensive presence + I'm thinking of running Keldeo as my Wall Breaker.

Super Power
U-Turn
Earthquake
Stone Edge
Not many people would expect a Scarf Landorus thus this set usually catches people off guard. With great speed and attack, Landorus is another one of my more useful Pokemon in battles. U-Turn just allow me to switch in the correct match up while damages the opponent. SuperPower is there for Air Balloon Excadrill. Stone Edge complete's the coverage with Earthquake which is its main stab.
Keldeo @ Choice Specs
Needless to say? Keldeo is there to bring up the offense of my team! As you can see from my previous teammates, they are not strong enough to break through walls. (No Setup from my team as well). This spot used to belong to Scarf Kyurem-B however Keldeo just does it better and cleaner. Choice Specs Hydro Pump is really scary once all its resistor are taken down. Usually a gg!

Hydro Pump
Icy Wind
Secret Sword
Secret Sword for coverage such as Chansey, Ferrothorn etc. Hydro Pump is its main stab for wall breaking capabilities. Icy wind for standard coverage as well as for lowering down the opponent's speed for my teammates to sweep. Lastly, Scald instead of Hp Flying or other HP for more accuracy.
Last but not least,
Talonflame Choice Band
Yup! This spot originally belongs to Greninja. But due to it being suspected, I'm trying out new teammates for this spot. Either Talonflame or Latios (Draco Meteor). Just felt that I need more physical support that's why Talonflame is here for the clean up.

Steel Wing
U-Turn
EV designed for maximum bulk as well as enough speed to outrun some priorities. Able to survive 2 stealth rock as well. Brave bird as late game sweeper, Steel Wing for Fairies (Which is greninja's role).
U-Turn for scout and Flare Blitz for stab. Was thinking of running Overheat instead of Flare Blitz to deal with ferrothorn more efficiently without losing too much of health.
Anyway, that's it about my team. It still have a long way to go so I'll need lots of help from everyone here. My team still doesnt do well with Talonflame :/ Please rate and suggestions (:
Here's one of my trial battle with Shofu.
