If a player writes “Ajani” on their decklist while two Ajani cards are legal, what is the consequence?

In this scenario, the appropriate consequence for a player writing "Ajani" on their decklist, when two Ajani cards are legal, is indeed a Game Loss. This is due to the fact that the decklist must be accurate and represent the specific cards that are included in the deck. When a player simply writes the name of a card that has multiple legal versions (in this case, the different Ajani cards), it does not clarify which specific version they are referring to. This leads to a situation where the player's decklist does not match the actual deck they are playing with, which is a significant issue in tournament play.

Accurate deck registration is critical for maintaining the integrity of the game and ensuring that both players are on the same page regarding the rules and the cards being used. Since the decklist is a legally binding document within the context of a tournament, any inaccuracies can lead to confusion or unfair advantages. Therefore, this infraction is serious enough to warrant a Game Loss, which reflects the severity of failing to provide an accurate account of the cards included in the deck.
