Under what condition is a deck considered not randomized?

A deck is considered not randomized when a player knows the position of one or more cards. This situation undermines the principles of randomness essential for a fair game. Randomization is crucial in Magic: The Gathering, as it ensures that players cannot predict the order of cards, which can significantly influence the outcome of the game. If a player is aware of where specific cards are located within their deck, they can manipulate their gameplay strategy, creating an unfair advantage over their opponent.

This condition highlights the importance of the integrity of gameplay, as any predictability can adversely affect the gaming experience. Maintaining a truly random state is key to ensuring that matches are fair and rely solely on the players' skill and decisions rather than knowledge of their decks’ arrangements.

In contrast, the other conditions listed do not necessarily indicate a failure of randomization in the same direct manner. For instance, a deck being in numerical order or containing too few cards may suggest suboptimal situations but do not directly imply the knowledge of card positions by a player, which is critical to defining lack of randomization. Additionally, while visibility into the deck's contents can affect game play, it does not inherently indicate that the deck itself is not randomized, as players might still not know the exact order of
