-Rules-
Alright, so "Standard Rules" entails the normal dealio of clauses. I suggest looking at the other Gym Leader posts for better elaboration. Basically:
No Ubers
No Soul Dew (though that doesn't matter since Latios/Latias are now ubers)
No Selfdestruct, Explosion, Perish Song, Destiny Bond when we've got one pokemon left
No OHKO moves
No 2 Pokemon may be the same
No Evasion moves
No more than one pokemon per team may be put to sleep at the same time.
But you should be hip to this jive already.
