3. The deck must be maintained in a single, uniform pile.
4. Players can’t look at or change the order of cards in their deck.
5. Each deck must start the game in a randomized state.
6. A player may only shuffle their deck when instructed to do so by an effect or in between games to randomize the deck.
7. A player may not look through any decks while in the game and may only look through their deck in between games.
8. Players can only draw cards from the deck.
