The Four Golden Rules

 * You cannot summon two Kings that dont each other at the same time or else they will both quickly return if they see each other
 * If you summon a King for a reason they dont believe is valid they have a right to punish you with an agreed punishment
 * If a King is in the middle of business that cannot be unattended he can reject your call. This is very disadvantageous as it can cause the user to waste their magic on nothing.
 * If the summoner is someone unauthorised by the original owner of the cards then the Beast King will attack the summoner.
