Deck

Your deck consists of the beasts, weapons, traps and zones that you use to play the game. It consists of a maximum of seventy cards, with a minimum of forty, that are shuffled and placed face-down on the deck space. You draw cards from the top of your deck and add them to your hand.

Effects can allow you to look through your deck and find certain cards, as well as draw extra cards. Every time you look through your deck, it must be shuffled afterwards to prevent you from knowing the order of your cards.
