Here is my lineup:

Garchomp @ Choice Scarf/Life Orb
Sand Veil
Naive
252 Atk/6 SpA/252 Spe
- Outrage
I chose Outrage as it is a Powerful STAB move, it should be able to do enormous damage to any non steel types
- Earthquake
I chose Earthquake as it is also is a powerful STAB move, which can do Super Effective Damage to a wide range of types and sizable damage to everything else
- Stone Edge
Stone Edge is here to take care of any flying types i come across (mainly gyarados) and it should be able to OHKO them fairly easily
- Fire Blast
Fire Blast is for Ice and steel types that are usually weaker in the SpD area, it also helps against grass types and can take care of Scizor no problems, i feel this is a must as i wont be carrying any other fire attacks on the team
Garchomp is going to lead off. I have 2 options for the item as i don't want to have 2 choice users in the team so when scizor comes in i can switch garchomp to Life Orb, but other than that it will always be using choice scarf to guaranty first attack unless beaten by a priority move

Porygon2 @ Leftovers
Trace
Bold
192 HP/216 Def/100 SpA
- Thunderbolt
Thunderbolt is here to OHKO gyarados, and to do decent damage to other water and flying types. i chose thunderbolt over discharge so i could get the guarantied OHKO on gyarados, it will also do at least 75% damage to starmie
- Ice Beam
Ice Beam is here to OHKO the likes of garchomp, salamence and flygon. It will also do good SE damage to Ground, Grass and Flying Types
- Recover
Recover is here for whenever my health gets low, which is generally after i take a hit from gyarados or dragons before i OHKO them
- Thunder Wave
Thunder Wave is here to slow down the opponent to give me a better chance of taking it out before it takes me out
Since Dragons and Gyarados are most likely to be running wild at the event as they were in 07, Porygon2 can survive a hit from them and then OHKO them. Also having the BoltBeam combo will help me with general coverage if i come up against something i cant do SE damage to

Lucario @ Life Orb
Inner Focus
Adamant
252 Atk/4 Def/252 Spe
- Swords Dance
Swords Dance is to give big attack boost so i can OHKO or do massive damage with the other 3 attacks
- Close Combat
STAB attack as well as high base power will help me deal big damage to anything that doesnt resist it and will almost certainly OHKO anything it does SE damage to
- Crunch
Crunch is here to deal with psychics and ghosts like Starmie and Gengar that were fairly common last time
- Bullet Punch
Bullet Punch is here because i cant use Extremespeed as it is learnt at lv 51, Bullet Punch gets STAB and will do some decent damage after a Swords dance, however there are alot more resistances with bullet punch so more than 1 swords dance may be needed for bullet punch to do lots of damage to pokemon that resist it
Lucario is going to be my end of game sweaper, after he gets a swords dance off there isnt much that can stop it from winning, i do have concerns with bullet punch not being as effective as extremespeed would be though
Reserves:

Scizor @ Choice Band
Technician
Adamant
240 HP/252 Atk/16 Spe
- Bullet Punch
Bullet Punch gets STAB and priority, with the choice band boost, Bullet Punch will do good damage to anything that doesnt resist it
- Superpower
Superpower is here to take care of normals, steels and the ever so common weavile
- Pursuit
Pursuit is good for when i detect a switch, it also is for doing good damage to starmie, other psychics and ghost types
- U-Turn
U-turn helps against psychics and the occasional grass type, however its main purpose is for scouting
Scizor will be used as a revenge killer and should hopefully serve as a good pokemon to clean up at the end of the match, standard CB scizor EV spread but i decided to move some EVs from HP to Speed to ensure i get the first attack if i come up against another CB scizor

Azelf @ Focus Sash
Levitate
Hasty
4 Atk/252 SpA/252 Spe
- Psychic
Powerful STAB move, can kill off Gengar as well as most fighting types easily, will do a good amount of damage to others
- Fire Blast
I chose fire blast as it was a powerful attack that could hit whatever psychic cant for at least neutral damage, will help me against the likes of bronzong, weavile, metagross, scizor and lucario who are sure to be fairly common this year
- Grass Knot
Grass Knot is sure to help me against any bulky waters and ground types i could come across, there were quite a few rhyperior last time so this can OHKO it with its 4x SE damage
- Explosion
When Azelfs focus sash activates or when it looks like it is going to go down after 1 more hit, i have explosion which should take the pokemon with me
If Garchomp isnt doing too well at leading, i can move it to somewhere else in the lineup and put azelf in as my lead, this is the standard azelf lead set however due to stealth rock not being that useful in 3v3 i switched it out for grass knot to get some more SE coverage

Gyarados @ Life Orb
Intimidate
Jolly
4 HP/252 Atk/252 Spe
- Dragon Dance
Dragon Dance is so Gyarados can get the attack and speed boost so it can start thinking about sweeping the opposition
- Waterfall
Waterfall is for STAB and can take care of Infernape, as well as other fires, Ground and Rock Types
- Ice Fang
Ice Fang will do 4x Damage on most dragons so more often than not will OHKO them, it can also provide good SE damage to flying, grass and ground types
- Earthquake
Earthquake is to take out any Electric types that will try and switch into Gyarados, it is also good for doing SE damage to steel types
If i spot a team that is weak to gyarados (which is quite easy for the opponent to do), i will move gyarados into the main team and it can finish off whatever garchomp does not
