"Armament" EX Deck (7) - You may begin the game with an "Armament" EX Deck of exactly seven Armament sub-rulers. You may not have more than one copy of any card in your "Armament" EX Deck and you may not have any High Armament sub-rulers in your "Armament" EX Deck.
As the game starts, you may reveal a card from your "Armament" EX deck at random and put it into your ruler area.
