These first six clauses are standard rules that, unless stated, will and shall be used in all battles that you will come across:
Evasion clause -You and your opponent can not use evasion increasing moves like double team and minimize. This clause does not include Accuracy reducing moves, as this is considered Pseudo Phazer.
Legit/legal clause - None of the pokemon can have illegal movesets, 999 in all stats, 255 EVs in all stats, or have been caught in places that they normally wouldn't have been caught at. An example of an illegal moveset would be would be a Magnezone with Flamethrower or Salamance with Ice Beam.
OHKO clause - You and your opponent can not use moves that causes instant one-hit knockouts. Some examples would be sheer cold, fissure, and guillotine.
Sleep clause - Only one pokemon can be to sleep (on your side of the field) at a time. The only time your opponent can use another sleep move is when your pokemon either wakes up or faints, then your opponent can use a sleep move again. The move Rest does not count toward sleep clause, so if your opponent were to put a Pokemon asleep because of Rest, you can still use a sleep inducing move on your opponent. If you put to sleep a Pokemon that has the ability Natural Cure and your opponent switches out this Pokemon, you can put to sleep pokemon without breaking this clause.
Species clause - You and your opponent can not use more then one of the same pokemon. This means that you or your opponent can not use two Infernapes or Garchomps or two of the same pokemon in general.
Uber clause - You and your opponent can not use ubers in a battle. Refer to the link at the bottom of this post for the tier list.
Those are all of the standard rules.

Now for rules that usually aren't used in standard battles but you might be asked to folow them:
Since everyone gives a rat's scrub about what I put here as a little sarcastic remark about these clauses, I removed it.
Focus Sash/Choice Item Clause - You and your opponent can not use more than one focus sash and choice items (choice scarf, choice specs, choice band) in a battle.
Freeze Clause - You and your opponent can not use moves that can freeze you after a Pokemon has already been frozen. You will have to wait for the frozen Pokemon to faint or thaw out before you can use another move that can possibly cause a freeze. Even though that it is a rare occurance to freeze your opponent's Pokemon, not many people feel like losing due to a freeze. A few moves that cause freeze would be Ice Punch, Ice Beam, Blizzard, and Powder Snow.
Item Clause - You and your opponent can not use Pokemon that hold the same items on their team. Leftovers is usually excluded from Item Clause, but it is up to the person who uses the Clause. Items that have the same effect, like Leftovers and Black Sludge (on poison types only), do not count as the same Item.
Luck items Clause - You and your oppnent can not use Items that rely on luck to be activated. Some examples are focus band, bright powder, and quick claw.
Self-KO clause - You and your opponent can not use moves that KO yourself when it is your last Pokemon vs your opponent's last Pokemon. This is to avoid draws in battle. Some examples are Self-Destruct and Explosion. Destiny Bond does fall under this clause if it works.
Skarmbliss/SkarmCressBliss Clause - You and your opponent can not use skarmory and blissey (and Cresselia, if you are using SkarmCressBliss Clause) on the same team. You can only have one of them on your team.
UBER/OU/UU Battle - You can request what kind of tier you want to play in. If you just want OUs in the battle, then post somewhere in your post or your title that you want an OU battle. If you want a BL battle, then post in your post or in your title that you want a BL battle. You do the same thing for the lower tiers as well. If you want to combine a few tiers together like BL/UU/NU, then post in your post or in you title that you want a BL and lower battle. A link to the tier list can be found at the bottom of this post. Asking for BL and NU battles is POINTLESS.
If you have any questions on why a clause is up there or why a clause is not up there, then feel free to PM me your questions and I will answer them to my fullest extent.
