What is a Deck/Decklist Problem?

A Deck/Decklist Problem encapsulates all scenarios where there is a discrepancy or issue regarding the construction or reporting of a player's deck in relation to the decklist submitted for a tournament. Each of the options contributes to the overall definition of a Deck/Decklist Problem.

Having too many cards in the deck falls under this category because it violates the deck construction rules. In most formats, a deck must have a specific minimum and maximum number of cards, making any violation a significant issue.

An illegal number of cards is also relevant, as it directly conflicts with the game’s regulations on deck size. If a player presents a deck with too few or too many cards, it constitutes a problem that must be addressed.

A mismatch between the decklist and the actual deck is critical as it can lead to unfair advantages or disadvantages depending on the cards recorded versus the cards physically present. This scenario can create confusion and enable inadvertent cheating, thus necessitating thorough checks to ensure compliance.

In summary, a Deck/Decklist Problem can involve any of these conditions, making the option of "All of the above" the most comprehensive and accurate choice.
