I built bulky offense with pivots to fully capitalize on Torterra's bulk and Lanturns incredible ability as a slow pivot. It's a pretty meta team, but it synergises well both defensively and offensively.
The core of the team is of course Torterra and Lanturn, with physically defesive, rocky helmet Xatu as part of the defensive side of the team. Torterra exists for rocks and hard hits, often punching holes in the opposing side quite nicely to allow for an easier time for Sneasel and Gurdurr. Lanturn runs an assault vest to ensure ability to eat hits on the switch, and more easily check things like Pyroar, boomburst Swellow and others which otherwise give the team a really hard time. Xatu works primarily as a para spreader, secondary pivot and hazard blocker (especially against spikes / t-spikes by Garbodor and Weezing). Rocky helmet is used to allow Xatu to roost up on any phyiscal attacker that can't setup on him or deal high enough damage. It's also useful for locking things like Scyther out on the predicted U-turn when rocks are up. Sneasel is just damn good, and when paired with Gurdurr it works to remove Psychics / Ghosts which can be difficult for the team to manage. Gurdurr is a no-brainer with Sneasel on board, it can comfortably clean up when psychics have been removed thanks to Pursuit or Knock. Finally, Mega-Audino is a perfect sneasel check, and acts as a win condition after steels have been whittled down by switching into Sneasel or Xatu, and Poisions (Weezing and Garbodor in particular) have been worn down by Sneasel and Gurdurr.
Overall, the team struggles with CM psychics if Sneasel happens to go down early, and struggles with CroDino, with WoodHammer being the only move on the team capable of dealing ~33% to fully defensive Mega-Audino. Earthquake on Magmortar and EVire can be problematic, but can generally be played around easily if they pack a Choice item. Lilligant can also do a serious number to the team, and therefore must be played around very carefully. Lilligant is much easier to deal with when rocks are up, and when it doesn't have HP Rock because Xatu can u-turn into Sneasel without much danger.
