Building Phase:
I wanted to use Zard X, because he is my favourite Mega Pokemon. This team is based entirely on him.
Then, I choose Keldeo, with Taunt for help Zard against Stealth Rock. It can help a lot even for Cobalion, the SR Setter against Defog (if the rocks aren't on my part).
Same concept for Keldeo, but only with Electric Type. He gives support against Mega Slowbro and Mega Sableye, having Prankster.
He setts da Stealth Rock. With Volt Switch and, with the other two pokemons (Thundurus and Tornadus-T), can create a Volturn area. He helps against some of the other setters like Skarmory, Ferrothorn, Forretress, and other Cobalions or Kion.
Scizor, other good pokemon. He has the SD set, so he can sweep every team. Unique threat is ScarfTran or Skarmory and Sableye.
And there is the star! Tornadus-T! That's the third pokemon of the Volturn part (see Cobalion). He has a good variety of moves, and a good speed! He has Air Slash>Hurricane because of his bad accurancy (not sure of how I have to written, I'm not english, sorry).
