Pokémon/Competitive battling/The "Job System"

Believe it or not, all of the above information I would consider "Basic Knowledge" to Pokémon. Now, we're in the land of "how to use it," not "what is it." First of all, no, we are not in Final Fantasy Series. Pokémon has a Job System, but the moveset of the Pokémon determines its job. If you're with me so far, then you should know that The Job System is not an official system, but it is there for competitive battlers to reference and put their Pokémon into categories. Most of the terminology above are official, or are created by Nintendo. From now on, most of the terminology will be player-created, since the players will take the information that is given and analyze every inch of it.

As I described above, there the Job System depends on a Pokémon's moveset. Some Pokémon can only do (or be proficient at) certain jobs, depending on its type and stats. Also, I will start referencing "Base Stats" of Pokémon. If you remember, "Base Stats" are not the stats of a Pokémon at a level, but it is rather an average ratio used for comparison purposes. I will try to define all of the terminology as well.

Physical Sweeper
Physical Sweepers are called so because these Pokémon literally "sweeps," meaning they take down many Pokémon. As you can guess, Physical Sweepers use Physical Attacks efficiently. A good Sweeper would be able to take down at least two Pokémon before fainting. Here is an example of a Physical Sweeper. This is also a good chance to get used to the format for describing a Pokémon:

Heracross (F) @ Leftovers           <-- Species, Gender, and Attached Item Trait: Guts                         <-- Trait EVs: 58 HP / 252 Attack / 200 Speed <-- Effort Values Distribution Adamant Nature (+Atk, -SAtk)        <-- Nature -Swords Dance                       <-- First move -Focus Punch                        <-- Second move -Megahorn                           <-- Third move -Rock Slide                         <-- Fourth move

This is the proper way to present a moveset. Although all of the information above is not necessary, it is good to have the Pokémon's moves and Nature. Regarding the moveset above, Heracross will Swords Dance to double its Attack, then Focus Punch, Megahorn, and Rock Slide will totally devastate your opponent if your opponent does not have a Pokémon that resists these moves. Note that just having four attacks on Heracross is not as effective as having Swords Dance then three attacks. This is an example of how Status Changing moves and Damaging moves can work together to create a good moveset.

Special Sweeper
Special Sweepers is another Sweeper that uses Special Attacks. Here is an example of a Special Sweeper:

Starmie @ Leftovers                 <-- Some do not have a Gender Trait: Nature Cure                  <-- Its other Trait has no effect EVs: 42 HP / 216 Speed / 252 Special Attack Timid Nature (+Spd, -Atk) -Surf -Ice Beam -Rapid Spin/Thunderbolt             <-- "/" indicates own preference -Recover

Notice now this Sweeper does not boosts up its attacking power but instead boosts up its staying power with the move Recover, so it could faint less quickly and deal more damage. Also notice something about the Effort Values of both Sweepers. Usually, maximum (252) EVs go into Attack or Special attack, depending on the type of Sweeper. There are also many EVs on Speed, since a Sweeper that attacks first takes less damage. The Nature of Sweepers often increases Attack, Special Attack, or Speed also.

Mixed Sweeper
Mixed Sweeper is merely a Sweeper that uses both Physical and Special Attacks. There aren't many of these, since it is better to specialize in either Physical or Special. However, there are a few Pokémon that make good Mixed Sweepers, and here is an example:

Swampert (F) @ Leftovers Trait: Torrent EVs: 38 HP / 128 Attack / 220 Special Attack / 124 Special Defense Brave Nature (+Atk, -Spd) -Curse -Earthquake -Ice Beam/Surf -Rest

Once again, Rest is for staying power so Swampert can come back and sweep some more. EVs is a problem for Mixed Sweepers since should it go into Attack or Special Attack? Curse takes care of that problem, since using Curse lets you concentrate more on Special Attack and other stats while giving reduced contribution to Attack. If you don't know, Curse increases Attack and Defense one stage while lowers Speed one stage. The reason this sweeper doesn't need Speed is because Curse makes it powerful defensively also, not just offensively. Since it's also defensive, it doesn't need to go first. Note that Physical and Special Sweepers usually have high offensive stats but low defensive stats.

Hazer
A Hazer is a Pokémon that uses Haze. Since Haze is such an important move, there are Pokémon that are designated to do this job. Here is an example of a Hazer:

Weezing (F) @ Leftovers Trait: Levitate                     <-- Weezing is now immune to Earthquake! EVs: 196 HP / 156 Attack / 158 Defense Relaxed Nature (+Def, -Spd) -Sludge Bomb -Haze -Will-O-Wisp -Pain Split/Rest

No, I'm not some kind of rapist that likes Female Pokémon; there is a reason for me choosing them. Male is the default Gender online, so many Pokémon using Attract are Female. For this reason, I use Female Pokémon so they can't be attracted.

Of course, a Hazer can't just Haze; it needs to have other jobs as well. Hazers are usually Tankers or Walls (more about this later), or Pokémon that can stall for a long time. This is because it needs to Haze many times if your opponent keeps Swords Dancing.

Pseudo-Hazer (PHazer)
A PHazer is a Pokémon that usually uses Roar or Whirlwind to force switching. There are other exceptions, but that will be explained later. PHazers are very similar to Hazers, but they are more popular because many Pokémon learn Roar. Here is an example of a PHazer:

Suicune @ Leftovers                 <-- More Leftovers? Yup, good item. Trait: Pressure EVs: 252 HP / 128 Defense / 64 Speed / 64 Special Attack Bold Nature (+Def, -Atk) -Calm Mind -Surf -Rest -Roar

Like Hazers, PHazers need to last, so Rest is there.

Physical Tanks
If you guessed it, Physical Tanks are intended to take damage. These can also deal damage, but by rather indirect moves with a possible addition of one damaging move that does not have to deal a lot of damage. Usually, it's Toxic or Will-O-Wisp plus Rest or Recover on a Pokémon with a very high Defense. Here is an example of a Physical Tank:

Steelix (F) @ Leftovers             <-- Notice how it's immune to Sandstorm Trait: Sturdy EVs: 252 HP / 80 Attack / 42 Speed / 136 Special Defense Impish Nature (+Def, -SAtk) -Earthquakev -Rock Slide -Explosion -Toxic

Steelix resists many Physical Attacks but can still dish out some damage. Steelix can never be a sweeper, but it serves its purpose as a Physical Tank well. In fact, Steelix doesn't even need Rest because it takes so little damage from Physical Attacks.

Special Tanks
Of course, Special Tanks are the Special version of Physical Tanks. Here is an example of a Special Tank:

Regice @ Leftovers Trait: Clear Body                   <-- Opponent cannot lower stats EVs: 200 HP / 200 Defense / 56 Special Attack / 54 Special Defense Bold Nature (+Def, -Atk) -Ice Beam -Thunderbolt -Thunder Wave/Counter -Rest

As you have guessed, neither Ice Beam or Thunderbolt will do much damage, but Regice is extremely tough to take down.

Walls
Of course there aren't many Mixed Tanks. Why? Their Defense and Special Defense stat is so high that they have no Attack or Special Attack at all! Of course, I'm talking about Shuckle, and for the sake of simplicity, let's just focus on Walls. Walls are like Tanks, but they are not expected to faint their opponents in any way. However, they are expected to take more hits than Tanks, so this job is for people who like to take their battles slow and steady. Here are two good types of Physical and Special Walls. There aren't much, so that's why they're in the same category:

Skarmory @ Leftovers Trait: Sturdy EVs: 196 HP / 30 Attack / 252 Defense / 32 Speed Impish Nature (+Def, -SAtk) -Spikes -Drill Peck -Rest -Roar

Blissey @ Leftovers Trait: Nature Cure EVs: 240 HP / 252 Defense / 14 Speed / 4 Special Attack Bold Nature (+Def, -Atk) -Aromatherapy/Heal Bell -Softboiled -Seismic Toss -Ice Beam

These two Pokémon often work together as a team and they make great Walls. Of course, they will probably not defeat any Pokémon alone, but they will resist most attacks thrown at them.

Cleric (Healer)
Clerics use Heal Bell or Aromatherapy to rid its team of Status Effects. These are very helpful if you encounter an opponent that tries to Paralyze your team to death, or if you have a Sleeping Pokémon on your team because it used Rest. Clerics are, as predicted, good tankers, so they can keep healing the party. Of course, one great Cleric is Blissey. Here is an example of another Cleric:

Miltank (F) @ Leftovers Trait: Thick Fat                    <-- Trait makes it a good Tanker. EVs: 168 HP / 172 Attack / 168 Defense Adamant Nature (+Atk, -SAtk) -Curse -Body Slam -Milk Drink -Heal Bell

Annoyer/Staller/Drainer
Annoyers annoy the daylights out of most people, using Double Team, Confuse Ray, Thunder Wave, Attract, and Rest as some popular annoying moves. Unlike Tanks and Walls, Annoyers don't absorb hits--they evade or try to make their opponents not able to attack. Sometimes, Heal Bell and Roar can send Annoyers packing. Sometimes, Annoyers are unstoppable after many Status Changes. I put Annoyers and Drainers together because most Annoyers find a way to replenish their HP, and it's usually from Leech Seed, Mega Drain, or Giga Drain. Yes, Mega Drain is an effective move if used right. Here is an example of a Drainer:

Ludicolo (F) @ Leftovers Trait: Swift Swim EVs: 252 HP / 130 Defense / 128 Special Defense Calm Nature (+SDef, -Atk) -Leech Seed -Toxic -Protect -Seismic Toss

I know Ludicolo can regenerate HP with the Rain Dish Ability, but this is a great Rain Dance counter since an Annoyer that goes first is almost too powerful.

Spiker
A Spiker uses Spikes. You've already seen a good Spiker, and that is Skarmory. However, Skarmory is not the only option, because if you want a Spiker as a starter (your leading Pokémon), then other Spikers are better. If you use Skarmory first, there is a chance that you will get eradicated by a Magneton with the Magnet Pull Ability. No example for now, because I'm going to introduce to you another job first.

Spinner
A Spinner uses Rapid Spin to get rid of those evil Spikes. You've already seen a good Spinner, and that is Starmie. But hey, a Pokémon can have two jobs, and a Spiker/Spinner combination is actually very good. Here is an example of a Spiner that is a Spinner as well:

Forretress (F) @ Leftovers Trait: Sturdy EVs: 252 HP / 70 Attack / 188 Defense Impish Nature (+Def, -SAtk) -Spikes -Rapid Spin -Earthquake -Explosion

If Forretress encounters another Spiker, then it will Rapid Spin after a few Spikes. Note that Rapid Spin only rids your opponent's Spikes, unlike Haze. After three Spikes or when it thinks that it will faint, then it uses Explosion, getting rid of a Pokémon. Of course Earthquake is there for a damaging move if is rarely used.

Baton Passer
A Baton Passer uses Baton Pass. Usually BP stands for Baton Pass and BP'er stands for Baton Passer. A BP chain includes two or more Pokémon Baton Passing different Status Changes and finally Baton Passing to a nearly indestructible Pokémon. However, a BP chain should be aware of Hazing and Pseudo-Hazing. Since I can't decide on which example to show you, here are examples of two Baton Passers:

Scizor (F) @ Leftovers/Leichi Berry <-- Increases Attack at 25% Health Trait: Swarm EVs: 110 HP / 108 Defense / 128 Speed / 164 Special Defense Careful Nature (+SDef, -SAtk) -Swords Dance -Agility -Hidden Power [Bug] -Baton Pass

Ninjask (F) @ Leftovers Trait: Speed Boost EVs: 6 HP / 252 Attack / 252 Speed Adamant Nature (+Atk, -SAtk) -Swords Dance -Substitute -Silver Wind -Baton Pass

Scizor is not a Sweeper, but if its current opponent poses no threat to Scizor after at least one Swords Dance and one Agility, then use HP: Bug to get rid of that Pokémon then Baton Pass. It is the same for Ninjask. If Ninjask's Substitute is not broken, then Silver Wind after Swords Dance could do wonders. But getting back on topic, just think how good Heracross, Tyranitar, or Machamp is with Swords Dance and Agility Baton Passed. Their Attack and Speed would have been doubled!

'er
Okay, so that's not really the name of the job. Basically, adding the prefix -er to any move can make it a job. You will commonly hear Tyranitar makes a good Dragon Dancer or Suicine makes a good Calm Minder. There are very few moves that have -er added after it though, because only moves that could significantly benefit a Pokémon would be a candidate. I assume that you don't need an example, because it's pretty self-evident what I will put. If you really want an example, then scroll up and look at Suicune's moveset (Calm Minder) or Heracross' moveset (Swords Dancer).

However, there is a point that I should make. Sometimes, we competitive battlers get lazy, and certain abbreviates starts to pop up. For example, CM stands for Calm Mind and CM'er is a Calm Minder. DD, SD, and ST stands for Dragon Dance, Swords Dance, and Sleep Talk, respectively. Even Pokémon is abbreviated to Pogey by some battlers!

Other Jobs
There are many other jobs, but they have become forgotten or not used when the Third Generation comes out. Generally, we consider the Third Generation battles to be of a faster pace, so many stallers or indirectly damaging Pokémon are out. Some examples are Toxi-Shufflers, Para-Shufflers, and Perish Trapper. I will only briefly describe them as most attention have now focused on the Third Generation and many battlers do not battle GSC much anymore.

Toxi-Shufflers
These Pokémon use Toxic then Roar or Whirlwind so all of their opponent's team's Pokémon are Poisoned.

Para-Shufflers
These Pokémon use Thunder Wave then Roar or Whirlwind so all of their opponent's team's Pokémon are Paralyzed.

Perish Trapper
Perish Trapping is not really gone, but it's not really for one Pokémon anymore. In GSC, one Pokémon uses Mean Look and Perish Song to prevent the opponent from switching out of the inevitable fate. However, in RSE/FRLG, there are much more opportunities to faint that Pokémon before it uses this combination, so two Pokémon must Perish Trap. I will give examples as the guide progresses.
