Hey guys, I am posting the this because I'm sure many new people will be unaware of these rules. Gym Leaders will often use these rules so read them carefully.
Sleep Clause
The first and most basic clause of any battle states that only one pokemon may be put to sleep by an opponent at any given time. It's fairly simple to follow, if you put one pokemon to sleep, you can't put another one to sleep until the previous wakes up. There are some conditions that may throw people off however, the first is Rest.
•Rest - When the opponent uses the move rest, it does not count towards this clause. This is because you did not put the opponent's pokemon to sleep, but it is actually vice versa. It's important to know this, as it will stop some arguments.
•Natural Cure - Keep in mind that some pokemon have the ability Natural Cure, which heals status upon switching out. If you are positive the opponent has this ability, it is ok to send the next pokemon of theirs to sleep. This is because the pokemon with Natural Cure is no longer asleep. The same thing applies for moves such as Heal Bell and Aromatherapy.
Evasiveness Clause
This clause is a very important one as it bans the use of anything that is involved with accuracy. This includes moves that raise evasiveness or lower accuracy, as well as items that lower accuracy.
•Banned Moves - Acupressure, Double Team, Minimize, Flash, Kinesis, Mud Slap, Sand-Attack, Smokescreen
•Banned Items - Lax Incense, Bright Powder
A little debate about abilities is quite confusing, but remember, abilities that affect these stats are not banned from being abused. Examples are Snow Cloak, Tangled Feet, ect. Those are allowed seeing as how they are the pokemon's ability and they can't always be avoided.
OHKO Clause
Moves that guarantee a OHKO on pokemon are banned from use. It's extremely unfair when used on pokemon like Articuno where they have access to moves such as Mind Reader (guarantees that Sheer Cold can hit the next turn). Moves are:
•Fissure
•Sheer Cold
•Guillotine
•Horn Drill
Species Clause
This clause allows the use of only one of each pokemon. This means that there can't be two Gyarados on your team or something of the such. Pre-evolutions of pokemon are allowed on the same team however, as they have different Pokedex numbers. Basically, if two or more pokemon on your team have the same Pokedex number, you're violating this clause.
Item Clause
this clause allows only one of each items is allowed, so basically having a team with two or three pokemon with leftovers is not allowed. Only one leftovers is allowed.
Destiny Bond Clause
This Clause does not allow destiny bond to be used when both opponents are at their last pokemon. If it is used it usually ends in a tie. If it is used then the one using Destiny Bond loses the match.
Selfdestruct Clause
The moves Selfdestruct, Explosion, Perish Song, Destiny Bond, or any other such move may not be used if both players only have 1 remaining Pokemon. If a player uses one of those moves under this condition, they automatically lose.
