A Balanced Game

Shroud Indestructible
Players may not sacrifice permanents. Exile all permanents that would enter the battlefield that were not cast from hand. If a player would cast a spell that counters another spell, tap all permanents that player controls. If a spell would cause a player to discard, all players discard that number of cards. All permanents excluding "A Balanced Game" lose all abilities except keyword abilities and mana abilities.
