[RATE MY TEAM] VGC18 "Helping Sand" Team

[Arctero]

It looks pretty solid like most sand teams. The only suggestions I have are possibly Drill Run over Earthquake, since it does spread damage and Tapu Bulu is running around with Grassy Terrain which weakens Earthquake. I do see the reasoning of Safety Goggles on Zapdos, but another 50% berry would also work to improve its longevity. Assurance could be a good replacement for Pursuit on Tyranitar since under tailwind/sand it looks like it will go after your faster pokemon and under trick room it will move after Stakataka and Cresselia. The last thing I have is entirely personal preference which is Stone Edge vs Rock Slide on Stakataka. There is also the choice of Swords Dance on Excadrill, Kamaal Harris used it when I faced him yesterday at an MSS.
But overall it is a really solid team, I look forward to hearing how it does!
