There's a lot more to it than that.
These are the official Elite Rules taken from Paradox's recent Rules thread.
ELITE:
- harming potions are illegal
- You may only have 6 dogs in the elite-Flying is disallowed in elite 4 fights
- You can only challenge the Elite Four once you have all the badges of a region, when the first Elite of that region is online, and when a Moderator/Admin is online.WARNING: ONCE YOU CHALLENGE THE ELITE FOUR IN A REGION, ALL BADGES FROM THAT ONE REGION ARE WIPED, AND YOU MUST COLLECT THEM AGAIN IF YOU WISH TO RECHALLENGE.
- Only one person can challenge the Elite Four at a time.
- You cannot be an Elite in more than one region.
- You can bring whatever you want in Elite fights except for two things:You are only allowed up to six dogs.You cannot bring harming potions.
- Elites time out after seven days.
- If a region has no Elites or a Champion, the first person to collect all badges in that region and who wishes to become the champion can become the champion.
-If a region has a Champion, but no Elites, anyone with all of the badges in that region can fight the Champion for their position. If they lose, they are offered a position in the Elite Four for that region.
- If a region has four Elites, but no Champion, anyone with all of the badges in that region can fight the Elite Four for Champion. If the challenger wins, they get Champion, and if they lose, they don't get any spots in the Elite Four, and the Elite Four will remain as it is.
