This is a pretty basic set and takes advantage of Omastar's Rock typing and its big Defense stat. Bring this in on a Cursing Pokémon and Reflect. Behind the Reflected wall you can Haze to nullify any stat-ups the opponent may have received. When you have a spare turn, attack with Surf (Omastar has an awesome Special Attack score, 328, on par with that of Raikou). When you have taken a lot of damage, Rest away your worries. This set is great against a lot of Cursers, but beware of Cursers that have Earthquake.
Defense and Special Attack are Omastar's two best stats, and this set takes advantage of them. Hydro Pump will deal a load of damage to things not resistant to it, and if they send in Exeggutor or Zapdos, Ice Beam will hit them hard. When low on health, Rest and Sleep Talk will continue the attacking fun. With Omastar's resistances, it'll get plenty of switch-in opportunities, especially in UU. Watch out for other Water-types.
Other Options
Toxic will whittle away at the Water-types that are Omastar's best counters.
Opinion
Omastar is a nice little UU tank that can also attack pretty hard. With great Defense, Rock typing, and a stellar Special Attack, Omastar can both support and attack pretty well. A great counter for Porygon2 and Cursing Sleep Talkers. However, other Water-types completely shut Omastar down, so beware.
Counters
Other Water-types use their resistances to Water and Ice to switch in easily and can capitalize on its neutrality to Surf to strike back for greater damage. This roster includes things like Octillery, Dewgong, and Golduck. Gyarados, while not resistant to Ice, can take hits with its high Special Defense and hit back with Zap Cannon or Surf; Mantine has even higher Special Defense, and can Surf Omastar as well. Electrics such as Magneton and Raichu can take a Surf and Thunderbolt Omastar's weak Special Defense. If Omastar doesn't have Ice Beam, Vileplume, Victreebel, and other Grass-types work very well, too.
