As soon as BW UU was released, the tier became swamped with game-breakers such as Victini and Kyurem, each bringing with them Drought and Snow Warning. How does Hippopotas and sand fit into this equation?
Very well. Sandstorm's main abusers consist of the Rock-types that both resist the V-creates and can tank them with their naturally high defense, as well as getting the 50% boost of their Special Defense to take Kyurem's repeated assaults. On top of that, many of the other threats in the metagame consist of special-attacking Psychic-types (Mew, Azelf, Celebi) that can be easily beat on with the Special Defense boost.
As far as Sand Rush and Sand Offense goes, Sandslash is yet unreleased so it's basically limited to Stoutland. I'm not exactly sure Hippopotas is worth it just for Stoutland, but if you so desire you can try it!
Sand abusers!
------------------------
Hippopotas@Eviolite - Impish
252 HP / 252 Def / 4 SpD
~ Stealth Rock
~ Earthquake
~ Slack Off
~ Roar / Yawn
In old UU, poor Hippo was thought of as mostly a throw-away Pokemon. All new with Eviolite though, this lil Hippo can actually take some hits and shuffle some damage around. Makes a pretty nice lead bar Taunt.
------------------------
Rhyperior@Leftovers - Adamant
232 HP / 16 Att / 16 Def / 244 SpD - Solid Rock
~ Earthquake
~ Stone Edge
~ Megahorn
~ Substitute / Roar | Dragon Tail
Absolutely monstrous. I was battling earlier today and took 55% from a Life Orb Moltres HP Grass. This guy can take hits and dish them out on a platter. Substitute is nice if you don't feel like predicting, but Roar|Dragon Tail can come in handy if you set up more entry hazards via Omastar, Nidoqueen, or Crustle. Rhydon can be used with Eviolite to get the same Attack and actually has higher defenses, but Leftovers + Solid Rock usually makes Rhyperior the better choice. Worth running a hippo just for this guy.
------------------------
Lairon@Eviolite - Careful
252 HP / 252 SpD / 4 Def - Rock Head
~ Head Smash
~ Earthquake
~ Magnet Rise / Iron Head??
~ Substitute / Roar??
This thing has RIDICULOUS defenses after Sandstorm and Eviolite. The given EVs give it 324 HP, 475 Defense, and a whopping 490 Special Defense, with pretty good specially defensive typing to boot. It deals some pretty dang good damage with Head Smash and takes no recoil because of Rock Head. Aggron of course is also an option, but this guy has far far superior defenses.
------------------------
Omastar@Leftovers - Bold / Calm
252 HP / 252 SpD / 4 Def - Shell Armor
~ Spikes
~ Toxic Spikes
~ Hydro Pump
~ Knock Off / Haze
Great setup for all your entry hazard needs. 358 SpD and 316 Defense with a Bold nature makes Spiking a breeze, and Omastar's typing allows it to switch into things like Victini with ease. Team reveal makes Toxic Spiking even easier and becomes important for any team with Chansey problems.
------------------------
Other notables include:
Regirock (Curse / Support)
Cradily (Curse)
Shuckle (Power Swap / Acupressure)
Crustle (Spiker / Shell Smash)
Aerodactyl (SubRoost Pressure)
Sand Partners!
------------------------
Nidoqueen@Leftovers - Bold
252 HP / 252 Def / 4 SpD - Poison Point
~ Toxic Spikes
~ Earth Power
~ Venoshock
~ Roar
General utility if you're having a bunch of Heracross or Hitmontop problems. Venoshock becomes super powerful once Toxic Spikes become active. Immunity to sandstorm makes Nidoqueen shine as a sandstall supporter.
------------------------
Golurk@Leftovers - Adamant
252 HP / 80 Att / 176 Def - Iron Fist
~ Substitute / Rest
~ Focus Punch / Hammer Arm
~ Earthquake
~ Shadow Punch
EVs are just random (like most of this threads lol) but overall is a great Pokemon for sand. Immune, hits hard, and most importantly acts as a spin blocker and at the same time a Fighting immune. Great check to fighters like Heracross and Hitmontop as well as a decent check to Cobalion also. That and he learns Fly. What a boss.
------------------------
Other notables:
Chansey (Wish, Aromatherapy, essentially immune to Special Attacks)
Deoxys-D (Spikes, Fighting resist)
Slowbro (Water resist, Fight resist, Regen)
Milotic (see above)
Celebi (near-perfect synergy with Rock-types, Nasty Plot cleaner)
Now it's time for your input!
