I used Greninja, M-Blaziken, Rotom-W, and Garchomp.
Greninja has Lum Berry, Mat Block, and three attacks. Use Mat Block to protect M-Blaziken on turn one, M-Blaziken Rock Slides opposing team. Should put both opponents into KO range next turn. If everything goes perfectly, then you start 4-2.
If Greninja's going to be outsped, use Protect while M-Blaziken gets a speed boost on the first turn. Lum Berry is to protect from status that isn't Mat Blocked. If out speeding Pokémon threatens Greninja, you can switch out for Rotom-W or Garchomp.
Rotom-W and Garchomp pair well because Garchomp is immune to Discharge and Rotom-W is immune to Earthquake. Rotom should be Sitrus for doubles. Garchomp I used Life Orb.
That was the logic behind my team. It took one try to get to 50 wins.
