There is something called the Standard Clauses that should be and are expected to be followed in battles taking place on this forum.
Species Clause: You may not have more than one of the
same exact Pokemon on your team. Also, try to refrain from using a
whole team of the gym leaders weakness as this gives an unfair
advantage.
Sleep Clause: No two pokemon can be asleep in a team at the same time (not counting self induced sleep).
Item Clause:
That means you may use more than one of the same item. Just try to
refrain from six focus sashes, and luck items don't actually help much
anyway -- they are based in luck, after all.
Evasion Clause: Moves that increase evasiveness or lower your opponent's accuracy are banned (it makes the game about luck)
OHKO Clause: No OHKO moves (Horn Drill, Sheer Cold, etc.) Also make the game about luck.
Self KO Clause:
This is rare but necessary, if you and your opponent are on your last
pokemon do not use moves like Explosion to induce a draw.
Hack Clause : No Hacks Gym Leaders have the right to trade if they suspect you have hacks.If you do not accept then you will not be awarded a badge.
***NEVER DISCONNECT IF YOU ARE LOSING OR HAVE ALREADY LOST!!! IT WILL NOT BE TOLERATED HERE!!
