Well, just saw this thread today and it looked like a great idea. For Team 1, I feel like a Scarfed Darmanitan would be great. It can destroy the other team and outspeeds them all short of priority. Here is my set:
Darmanitan @ Choice Scarf
Ability: Sheer Force
Adamant nature
Evs: 252 Atk / 252 Spd / 4 Hp
-Flare Blitz
-U-Turn

252+ Atk Darmanitan Earthquake vs. 0 HP / 0 Def Infernape: 336-396 (114.6 - 135.1%) -- guaranteed OHKO
252+ Atk Sheer Force Darmanitan Rock Slide vs. 216 HP / 0 Def Multiscale Dragonite: 130-153 (34.4 - 40.5%) -- guaranteed 3HKO

There are all the revlevant Calcs. Should probably change Evs slightly but don't really know what good it will do. This set will smash through most of Team 2 after some Stealth Rock Damage. It is also faster then their whole team and acts as a great revenge killer. It can punch huge holes in the team and wreck havoc.
For Team 2, I think a Scrafty should do some damage. Here is the set I would use.
Scrafty @ Assualt Vest
Ability: Intimidate
Adamant nature
Evs: 252 Atk / 252 Hp / 4 SpD
-Ice Punch
-Knock Off
-Drain Punch
-Fake Out
-1 4 Atk Teravolt Kyurem-B Fusion Bolt vs. 252 HP / 0 Def Scrafty: 68-81 (20.3 - 24.2%) -- guaranteed 5HKO
252+ Atk Scrafty Drain Punch vs. 252 HP / 0 Def Kyurem-B: 210-248 (46.2 - 54.6%) -- 9% chance to 2HKO after Leftovers recovery
252 SpA Life Orb Sheer Force Landorus Focus Blast vs. 252 HP / 4 SpD Assault Vest Scrafty: 239-283 (71.5 - 84.7%) -- guaranteed 2HKO
252+ Atk Scrafty Ice Punch vs. 4 HP / 0 Def Landorus: 308-364 (96.2 - 113.7%) -- 81.3% chance to OHKO ( Guranteed KO after Fake Out)
-1 4 Atk Ferrothorn Power Whip vs. 252 HP / 0 Def Scrafty: 73-87 (21.8 - 26%) -- 3.2% chance to 4HKO
252+ Atk Scrafty Drain Punch vs. 252 HP / 252+ Def Ferrothorn: 126-150 (35.7 - 42.6%) -- 91.7% chance to 3HKO after Leftovers recovery
This set can easily take their first three pokemon while hard to counter outside of Fairy-Types who are beaten by Mega-Scizor. It has lots of bulk and can hit a variety of threats very hard. Also has nice +3 priority to hit faster threats with a little health left if Dragonite and Mega-Scizor don't want to come in or can't. Hopefully people choose these pokemon to aid their respective teams.
