the strategy behind this is basically to support the whole team with Ninetales aurora veil and dragon dancing up with Tyranitar while Excadrill and Lele break through a lot of Pokemon and Magnezone trapping especially mons like Skarmory, Celesteela and Ferrothorn. i chose Garchomp as a special offensive lead to pressure other Leads like Ferrothorn (FB does around 90% to standard Ferrthorns and has a 25% to OHKO phys def Ferrothorns) and defensive Landorus right from the beginning (DM does around 55% to standard defensive Landorus).

hope you like it! :]
