My XY Preview I'm mostly taking from my preview so it's not plagiarism guys. I don't think much needs to be changed from it, so yeah :x Skeleton (Move your mouse to reveal the content) Skeleton (open) Skeleton (close) Overview ######## Omastar possesses a decent base 115 Special Attack stat. It has access to one of the best boosting moves in the game, Shell Smash. It possesses an excellent base 125 Defense stat. It has good typing in conjunction with Weak Armor. Its access to Swift Swim makes it a potent threat in the rain. Rock typing allows it to resist the Normal and Flying type attacks that Gorebyss, a similar Shell Smash user, does not, while also giving it extra resistance to Fire. It is slow; it can be outsped by common Choice Scarf users even at +2 Speed. It has a massive weakness to Grass, as well as possessing common weaknesses such as Fighting, Ground, and Electric Its movepool is extremely small, though it gets good coverage with Hydro Pump, Ice Beam, and Surf, as well as Shell Smash as stated before It is weak to priority moves such as Mach Punch and Vacuum Wave. Nerfed by lack of permarain/sand to boost SpA and SpD respectively Omastar's typing helps it check on of the biggest threats in Talonflame and leave it at that. Shell Smash ######## name: Shell Smash move 1: Shell Smash move 2: Hydro Pump / Surf move 3: Ice Beam move 4: Hidden Power Grass ability: Swift Swim / Weak Armor item: White Herb / Lum Berry nature: Modest / Timid evs: 4 HP / 252 SpA / 252 Spe Moves ======== Access to godly boosting move Shell Smash turns Omastar into a dangerous boosting sweeper Surf is more reliable than Hydro Pump, but it loses out on some KOs on tanks such as Conkeldurr at max HP Ice Beam is a great coverage move to hit all the Dragon-types roaming around Though Hidden Power got nerfed, Hidden Power Grass is still a vital coverage move to have if it wishes to hit opposing Water-types Set Details ======== Timid allows it to outpace neutral base 100 Speed Scarfers, though Modest is preferred for extra power White Herb allows it to keep its defenses, which is the ideal item for a mid- or late-game sweep, and also because Omastar is slow Lum Berry prevents it from being paralyzed or otherwise statused, allowing it to continue its sweep and not be crippled Usage Tips ======== If using Weak Armor, use Omastar's great defense to its advantage to switch in on a multitude of physical Fire-type moves. Shell Smash Omastar can be a serious threat if used right, but it usually only has one shot to pull off a sweep so make sure that checks and counters are either eliminated or seriously weakened before bringing it in Make sure specially defensive Pokemon like Blissey or Snorlax are seriously weakened, while Choice Scarf users faster than Omastar or priority users that could be a threat should be eliminated altogether unless they are weak enough to die on the switch to hazards or they could easily come in and ruin your day Bring Omastar in on a Fire-, Flying-, or Rock-type such as Talonflame when checks and counters are gone or severely weakened and profit Though it is quite a gambit, if you bring in Omastar a little early, instead of setting up, you could try to score a hit on a check or counter on the switch and switch out to sweep later Team Options ======== A Fire-type teammate such as Heatran or Charizard is extremely useful for getting rid of Ferrothorn and/or Mega Venusaur, both of whom completely counters Omastar. A hazard setter is useful for any sweeper to turn quite a few 2HKOs into OHKOs - Omastar is no exception If using Swift Swim, be sure to have Politoed or a Rain Dance user on the team to take advantage of it Omastar has trouble with many special walls, so strong physical attackers like Talonflame can be used to get rid of them. Some of the top-tier special walls, such as Chansey, Blissey, and Tyranitar, are weak to Fighting, so having one like Conkeldurr or Breloom is also useful. Other Options ######## It has access to all forms of entry hazards and can be both a suicide lead or a defensive spiker, though it's usually outclassed by other hazard setters such as Forretress and Skarmory Checks & Counters ######## Choice Scarf users (Garchomp, Lati@s, etc) Lucario (Vacuum Wave) Special walls (Chansey, Blissey, Assault Vest Snorlax and/or Goodra) Ferrothorn Mega Venusaur Gyarados (especially if it has Earthquake) Mach Punch users (Technician Breloom and Conkeldurr) Rotom-W Overview ######## Omastar has one thing that allows it to separate itself from other potent rain sweepers: its access to Shell Smash, one of the best setup moves in the game. If you take into account its decent base 115 Special Attack, Omastar is able to function as an extremely deadly sweeper that can tear teams apart even without weather support. It also has a great base 125 Defense and a great defensive typing. Omastar differs slightly from Gorebyss, another Shell Smash user, due to its Rock typing, allowing it to resist Normal- and Flying-type attacks, particularly those of Talonflame, a big threat in the current metagame. Though Omastar can be extremely deadly, it does have many noticeable flaws that prevent it from being used more often. The most obvious flaw is that Omastar is extremely slow, and can be outsped by common Choice Scarf users even at +2 Speed. Omastar also has a massive x4 weakness to Grass, as well as other common weaknesses to types such as Fighting, Ground, and Electric. Its movepool is also extremely limited, though it still gets very good coverage with Hydro Pump and Ice Beam. It is also weak to the common priority moves Mach Punch and Vacuum Wave. Finally, the lack of permanent rain and sand hampered Omastar's utility in OU as it really loves the power or defense boosts either weather provides. Shell Smash ######## name: Shell Smash move 1: Shell Smash move 2: Hydro Pump / Surf move 3: Ice Beam move 4: Hidden Power Grass ability: Swift Swim item: White Herb / Life Orb evs: 4 HP / 252 SpA / 252 Spe nature: Modest / Timid Moves ======== Shell Smash is the most important move on what is Omastar's only viable set, as it allows Omastar to become an immediate threat in just one turn. Surf is Omastar's most reliable STAB attack, but it will lose out on KOs that Hydro Pump can net on sturdy tanks such as Mega Aggron. Ice Beam is a great coverage move to hit not only the Grass-types that resist Omastar's STAB but also to seriously damage or KO the many Dragon-types roaming around the tier, such as Dragonite and Garchomp. Finally, Hidden Power Grass is an essential move to have if Omastar wishes to hit opposing Water-types. Set Details ======== While a Timid nature allows Omastar to outspeed neutral base 100 Speed Choice Scarf users, a Modest nature is preferred for the extra power. As for item choice, a White Herb allows Omastar to keep its defenses after one turn of setup, which is ideal for a mid- to late-game sweep, as Omastar is still rather slow. However, a Life Orb will noticeably boost Omastar's power and actually allow it to do some damage before setting up. The power received from a Life Orb is important for Omastar to stick out in a metagame filled with hard hitters. Finally, a Lum Berry is worth considering as it will prevent Omastar from being paralyzed or crippled by other status; this is useful for preventing a Thunder Wave from Thundurus or Blissey stopping your sweep cold. Usage Tips ======== Shell Smash Omastar can be a serious threat if used right, but it usually has only one shot at pulling off a successful sweep, so make sure that its checks and counters are either eliminated or seriously weakened before bringing it in. These threats include naturally fast Pokemon, Choice Scarf users, and special walls. One of the most common threats in the metagame, Talonflame, is incredibly easy to set up on, as Omastar 4x resists its Flare Blitz. However, keep in mind that Choice Band Talonflame can 2HKO Omastar with a priority Brave Bird. Finally, if Omastar is brought in a little early, it can try to use an attack instead of setting up to damage a check on the switch and then immediately switch out, but this is quite a risky tactic. Team Options ======== A Fire-type teammate such as Heatran or Charizard is extremely useful for getting rid of Ferrothorn, which completely counters Omastar, though any teammate with a Fire-type move will also suffice. An entry hazard setter is useful for any sweeper to turn quite a few 2HKOs into OHKOs, and Omastar is no exception. Omastar has lots of trouble with special walls, so having a strong physical attacker like Talonflame is useful for getting rid of them. Talonflame is also able to get rid of Mega Venusaur, which is arguably Omastar's best and most common counter, with Brave Bird. Many top-tier special walls, such as Blissey, Chansey, and Tyranitar, are weak to Fighting-type moves, so having a Fighting-type in your team, such as Conkeldurr or Breloom will greatly help Omastar pull off a successful sweep. Finally, if using Swift Swim, be sure to have Politoed or a Rain Dance user to take advantage of it, as there are lots of Pokemon that Omastar can't outspeed without it. Other Options ######## Unfortunately, Omastar doesn't have many other options that it can fall back on. It does have access to all forms of entry hazards, so you could use it as a defensive or suicide Spiker, though it is generally outclassed by those with more bulk or more Speed, such as Forretress and Skarmory. Checks & Counters ######## **Choice Scarf Users**: Omastar is quite slow, so Choice Scarf users such as Garchomp can outspeed it even when it's at +2 Speed and KO it with a powerful attack. **Special Walls**: Special walls such as Chansey and Blissey, as well as tanks such as Assault Vest Goodra or Snorlax, can take Omastar's hits with relative ease and can either cripple or outright KO it. **Priority Users**: Omastar is weak to a few common priority attacks; Mach Punch from Conkeldurr or Technician Breloom will easily take it out. **Grass-types**: Although Omastar has Ice Beam to handle most Grass-types, there are a few that it just can't deal with. Mega Venusaur and Ferrothorn both take neutral damage against Ice-type attacks thanks to Thick Fat and Steel typing, respectively. Both Pokemon also have 4x super effective STAB Grass-type moves to take Omastar down with ease. **Water-types**: Due to the nerf on Hidden Power this generation, Omastar has a much harder time dealing with opposing Water-types. Gyarados takes neutral damage Grass-type attacks, and its bulky variants essentially counter Omastar, especially if it has Earthquake. Rotom-W is also a bulky Water-type that can take advantage of its STAB Electric-type moves to take down Omastar.
