[OVERVIEW]
Omastar is one of the premier rain sweepers in ADV Ubers, utilizing Swift Swim to outspeed most of the unboosted metagame in rain barring very fast Pokemon such as Ninjask and Deoxys-S, as well as Rayquaza with its unique Air Lock ability. Omastar exerts strong offensive pressure with its high Special Attack stat and punishes switches by laying down Spikes to wear down the opponent's team. Its Rock typing and high Defense also protects it from the premier revenge killer in the metagame, Deoxys-A, instead revenge killing it in rain. Offensive rain teams appreciate Omastar's wallbreaking ability and how it reliably forces progress through setting Spikes and using Thief to steal items, limiting the longevity of opposing teams. Omastar does suffer from having very low special bulk and weaknesses to common offensive types, meaning that many Pokemon it can't OHKO such as Latios, Mewtwo, and Groudon can easily take it out, neutering offensive potential from the teams Omastar finds itself on. It also faces some competition from Qwilfish, another Swift Swim user with access to Spikes and a useful tool in Self-Destruct.

Set Description
=========
Omastar functions best as a revenge killer and should be used very offensively, forcing switches against weakened or offensive Pokemon and threatening bulky ones with its item displacement ability and Spikes. Fast-paced rain teams love Spikes and Omastar's wallbreaking wearing down and threatening defensive Pokemon. When boosted by rain, Hydro Pump is an incredibly powerful STAB option, being used over weaker, more accurate Water-type moves to achieve feats such as possibly 2HKOing specially bulky Pokemon like Deoxys-D and Jirachi. Ice Beam is used for Dragon-types like Latios, Latias, and the rare defensive Salamence, as well as bulky Water-resistant Pokemon like Celebi, being strong and having a good amount of PP to fire off in a longer game. Thief is a very useful move that Omastar is one of the few users of, being able to remove Leftovers from Pokemon like Blissey and Snorlax while holding no item, as well as the very important Soul Dew from Latios and Latias. This deters a lot of Pokemon from switching into Omastar making Thief a very effective and important part of its success. A Timid nature with 252 Speed EVs is used to outrun maximum Speed Deoxys-A in rain.
Team Options
========
Due to it succeeding best on offensively-inclined rain teams, Omastar's best partners are ones that can take advantage of it setting Spikes and stealing items to chip down common threats. Kyogre is a mandatory partner, being the only way to set permanent rain for Omastar to thrive in. With an extensive movepool, it can also pressure Blissey, Latios, and Latias, which Omastar loves having chipped or removed from the game. Petaya Berry Deoxys-A is another potent rain attacker, using mixed wallbreaking power with Superpower to threaten checks to Omastar such as Blissey and Snorlax while heavily denting others like Latias with boosted Ice Beam. Snorlax serves as a bulky check to offensive Pokemon that Omastar can't break past unless chipped, such as the Lati twins and Mewtwo, while appreciating Spikes wearing down its own checks like Forretress and Metagross. With Spikes being such a crucial part of Omastar's gameplan, Gengar works as a solid offensive spinblocker to deter Forretress, which can live a Hydro Pump from Omastar in rain. Gengar also has access to Thief, enabling a double Thief core that can displace multiple important items from the opponent.

Other Options
=============
Mystic Water and Toxic are both options Omastar can use instead of Thief, letting it hit harder and threaten poison on walls, respectively. The presence of Refresh Latios and Latias makes the latter much harder to pull off, though, with them threatening it out while no longer fearing losing an item. Protect Snorlax with Immunity can also take even Mystic Water-boosted hits while not fearing Toxic. A Modest nature can also be run to give Omastar more power while still outrunning maximum Speed neutral nature Deoxys-A, but no longer outspeeding maximum Speed positive nature Deoxys-A can be costly. A Petaya Berry set with Substitute can make Omastar a potent late-game sweeper, but it loses the utility of Thief or immediate damage from other options like Mystic Water.
Checks and Counters
===================
**Kyogre**: Kyogre—Omastar's best partner—is also one of its hardest walls. Hydro Pump does little damage even in rain, and Kyogre can threaten it with an OHKO from Surf or Hydro Pump, inflict paralysis with Thunder Wave, or heal off any damage Omastar does with Rest.
**Blissey**: Blissey easily survives multiple Hydro Pumps and can spread status or set up Light Screen to further wall Omastar. However, it hates having its Leftovers stolen by Thief and being worn down by Spikes as it switches in.
**Rayquaza**: Rayquaza can effectively disable Swift Swim with Air Lock, allowing it to outspeed Omastar and OHKO with Earthquake even in rain.
**Bulky Revenge Killers**: Omastar struggles to OHKO some very powerful but bulky Pokemon even in rain such as Mewtwo, the Lati twins, and Choice Band Snorlax or Metagross, meaning they can often force Omastar to switch out or sacrifice itself for some damage.
**Groudon**: Groudon setting sun makes Omastar essentially unviable, removing its revenge killing niche. Groudon can also easily outspeed Omastar in sun and OHKO it with Earthquake.
