So, per feedback, I'm getting the feeling that Mamoswine isn't the best fit for the team. Hadn't considered Magic Guard Clefable as a Cleric, and I might consider Quagsire just for its ability to shut down water-types. I'm also looking in to Pallosand (Shore Up seems to be pretty good recovery on a Sandstorm team, and Water Compaction, while not as good as Water Absorb, is still a good ability) with an Expert Belt as a potential hybrid Defense-wall/Special Attacker with the added benefit of acting as a counter for Machamp (100 Sp. Atk isn't bad, especially for a Ground/Ghost with Earth Power, Energy Ball, and Shadow Ball), or possibly a Blissey with Safety Goggles for a Cleric.
Also, probably a good idea to swap out Rhyperior's sand for the vest. Dragon Tail is a move I hadn't realized the potential of when combined with Skarmory's entry hazards (mostly avoided it because it was a -6 priority move with less than 100 accuracy), and it is definitely a better option than slowing down an already slow attacker.
Might also swap out Stealth Rock for Brave Bird on Skarmory. Tailwind, as afterlifex stated previously, is necessary to cover for the lackluster speed on the team, and Whirlwind is used to force a swap, but Tyranitar has access to Stealth Rock, and it's the team opener, so I think Stealth Rock would be a better idea on Tyranitar than Skarmory (especially given its attack probably being enough to land a KO and force an entry before it's out). Stone Edge isn't as reliable of a move as the others Tyranitar has on it, so it's probably going to be replaced (what's more, Stone Edge is a TM move, so it's easy to swap back on if I want to test out how another move would work in comparison).
Lastly, I'm not thinking that D.Dance has a spot on Tyranitar. It's mostly there to get the Sandstorm and Stealth Rock set up, and hopefully get in a KO and/or T.Wave in the process. I do, however, think that Garchomp would benefit from it. It's the obvious choice for a D.Dance user, though, so people would definitely expect it, and swapping out any move currently on it opens a few potential problems (unless I'm overthinking things and swapping out Stone Edge is as good an idea as I initially thought, since D.Claw and Poison Jab both work on most things).
Any other suggestions?
