Ok heres the rules for my gym
First thing is NO UNLEGIT POKEMON (That means pokemon that break the 510 EV limit, unlegit movesets etc)
No Ubers (Other legends are fine, things such as Legendary Birds, Dogs etc. If you would like a Uber list then just ask)
Evasion Clause (No Double Team or Minimize)
OHKO Clause (No one hit KO moves like fissure)
Sleep Clause (Only one pokemon on each team may be asleep at one time)
Super Effective Clause (You may only have ONE pokemon that is super effective against flying types such as Rock, Ice and Electric)
Disconnection Rule (This sounds harsh I know as sometimes its not a persons fault but if theres a disconnection the person with the most pokemon will win.)
Friendcode etc:
My friend code is 1375 4602 2718
Ill edit this post if I have anything more to put.
If you have any questions then ask them in this post. Thanks and happy battling
