You must have beaten all gym leaders and obtained 8 badges in order to challenge the Elite 4.There is something called the Standard Clauses that should be and are expected to be followed in battles taking place on this forum.
Uber Clause:
No UBERS ALLOWED (see
TIER list)
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 Elite 4's 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 Elite 4 have the right to trade if they suspect you have hacks.If you do not accept your victory will not count.
You may not use more than two super effective types
Moody Clause - A team cannot have a Pokemon with the ability Moody. This rule was implemented for BW tiers by acclamation on June 7, 2011.
***NEVER DISCONNECT IF YOU ARE LOSING OR HAVE ALREADY LOST!!! IT WILL NOT BE TOLERATED HERE!!
