I used a trick room team with my Slowbro.
My Bold max def. max hp Bro tanks a +2 EQ from mega Garchomp so that thing is always checked.
And at the beginning I just set up trickroom and just hit hard with Amplified Rock-Reuniclus, LO-SF-conkeldurr, Amplified Rock-slowbro, Curse-Gyro ball-Ferrothorn, SD-aegislash, and SD-Escavalier.
It was pretty easy for my iirc.
