I found this really useful: Pokemon Competitive Battling Strategies
A team should not have all Sweepers, all Tanks, or all Annoyers
A sweeper is a Pokemon that can charge up energy, and then wipe out an entire enemy team with its increased stats. (Such as dragon dance Tyranitar)
An annoyer is a Pokemon that can inflict moves that annoy the opponents, with status effects, etc. (Such as Golbat)
A tank is a Pokemon with a lot of health. (Such as Blissey)
Here are some of the teams the website suggests:
- Physical Sweeper, Physical Sweeper, Special Sweeper, Special Sweeper, Tanker, and Annoyer.
First, two of the six Pokémon need to also be a Hazer or Pseudo-Hazer.
This will be the theme to all of the sets, because Hazing is so
important that it's critical to have some Pokémon doing it. Second, a
Spinner would be a great addition to this team, since this team relies
mainly on attacking power and Spikes would greatly hinder that. You
might make one of your Special Sweepers a Starmie since it can be both
a Special Sweeper and a Spinner. Also, you might want to make your
Tanker or Annoyer a Pseudo-Hazer since they are the prime candidates.
Again, start with Zapdos or another fast Pokémon.
- Baton Passer, Physical Sweeper, Physical or Mixed Sweeper, Special Sweeper, Tanker, and Wall.
Ninjask is perfect for this team, because Speed Boost will benefit all
Sweepers and even Tanks. Plusle and Minun are also great because they
benefit your special sweeper, rather than your Physical one, by using
Nasty Plot. If you do manage a Swords Dance with Ninjask or a Nasty
Plot with Plusle/Minun, then Baton Pass it to your Physical/Special
Sweeper because it can really Sweep. The Tanker and Wall are for
switch-ins, such as when the Sweeper encounters something that you're
sure it cannot KO. The Tanker or Wall would then absorb the damage,
sending out Ninjask again or another Sweeper when you predict a
switch. This relies on some prediction. You can have only one
Pseudo-Hazer in this team since this is a fast-paced team, and you
should try to defeat your opponent before they can set up their Stat
- Physical Sweeper, Special Sweeper, Physical or Mixed Sweeper, Drainer, Tanker, and Cleric.
This is a Sleep Talking team, even though it doesn't show it. Two of
the Sweepers should have Rest, and so should the Drainer and possibly
the Tanker. Then, the Cleric should pop up from time to time to use
Heal Bell, and it would be good if this Cleric is a Tanker or Wall
(not someone that can't survive very long like Vileplume or Miltank).
This is actually an Annoy Team, even though it has many Sweepers. With
Rest + Heal Bell, the Sweepers won't seem to faint!
- Spiker, Physical Sweeper, Special or Mixed Sweeper, Tanker, Drainer, and Cleric.
This team is purely Annoying. The Sweepers are for Stallers or
Drainers such as Ludicolo, but with a Spiker, Drainer and a Tanker,
you will seriously aggravate your opponent, especially with a Cleric.
A Sleep Talker would fit the theme here, and of course two or more
Hazers or Pseudo-Hazers are needed. The more you Roar or Whirlwind,
the more your opponent will be hurt with Spikes.
- Baton Passer, Baton Passer, Physical Sweeper, Physical Sweeper, Special or Mixed Sweeper, and Magnezone/Probopass.
This is really a weak team in the hands of a novice but powerful in
the hands of an experienced battler. It is true that Roar and
Whirlwind clear Status Changes, but a good battler would know what to
Baton Pass, when to Baton pass, and when to send in Magnezone or
Probopass. One of Magnezone's traits is Magnet Pull, which prevents
Skarmory from switching, getting rid of one major Pseudo-Hazer.
Probopass can also have this trait. This team relies heavily on
- Zapdos, Umbreon, Celebi, Drainer, Physical Sweeper, and Special Sweeper.
Once again, this team requires a lot of prediction and should only be
handled by experienced battlers. Umbreon can use Mean Look and Baton
Pass to Celebi and Celebi can use Perish Song. Zapdos' Thunder Wave
and Substitute makes this strategy easier, especially because Umbreon
and Celebi will not take that much damage from a Paralyzed Pokémon.
- Spiker or Drainer, Special or Mixed Sweeper, Heracross, Magnezone, Dugtrio, and Shuckle.
If you're been battling for a while, then you should know what to do
here. Shuckle's Wrap and Encore keep its opponent in while you switch
to Heracross or Dugtrio, doing damage. Magnezone is there once again
for Skarmory, and it's nice to have a Spiker to take off more damage
as your opponent switches since this is a major Annoy team. As always,
you need a Sweeper to take down those Stallers.
Some more terms:
For example, if you have a pokemon that is weak against a water type, try to include a grass type in your lineup.
Finally, make sure you don't have too many pokemon of the same type or else facing an opponent with a pokemon that is super effective against multiple pokemon will be difficult.
