The Tower of Heaven is an ancient structure that stretches deep into the   clouds, the heavens, and far beyond. It is composed of a material   similar to rock, but far more durable and nearly impossible to break.   Most of the structure is open-air giving a good glimpse of the clear   sky. Moss and other small plant life have grown on the outcropping on   the rock-like material with small butterflies flying about. There are   small streams and pools of water within the structure for Water attacks   and Water Pokemon. The battle will take place within one of the many   chambers of the tower. 
All moves can be used within the Tower of Heaven. However, there is a   catch. Within my hands is the Book of Laws. At the end of each round,   I'll write down a new law. The laws restrict what attacks, actions, or   commands you may or may not take in battle. Violation of any law in   battle will still allow you to perform the command, however the offender   will be struck down with a lightning bolt that deals 10 damage flat  and  ignores abilities, weakness, and resistance. The lightning bolt  cannot  be deflected, dodged, evaded, or otherwise blocked. It will hit  the  Pokemon behind a Substitute, find its way through Double Team, and  will  go through Wonder Guard. Pokemon that are immune to Electric  attacks by  ability or typing will still be struck down and will gain no  benefit  such as Motor Drive's Speed boost. Violation of multiple laws  in an  action will drop down multiple lightning bolts on the offender  depending  on how many laws they've broken in a given action.
For instance, Pikachu decides to use Thunderbolt on a Staryu. If I   restrict the usage of Thunderbolt, Pikachu will be smote once for 10   damage. If I restrict the usage of Thunderbolt and all Electrical   attacks, Pikachu will be hit twice for 20 damage. Finally, if I restrict   the usage of Thunderbolt, Electrical attacks, and super-effective   moves, Pikachu will be struck thrice for 30 damage.
If there's any questions or need clarification on anything, PM me.
Summary: All moves can be used initially, however new laws added   in each round will restrict what commands can be used. Violation of any   law will be penalized with a lightning bolt dealing 10 damage flat   ignoring typing and abilities. Combatants can be penalized multiple   times in an action.
