If a player searches for three cards but only two are present, what should happen?

When a player is instructed to search for a certain number of cards and there are fewer cards available than what is being searched for, the correct action is to find only the available cards. In this case, if the player is searching for three cards but only two are present in the deck or zone they are searching, the player will find those two cards that are available.

This action aligns with the rules governing searches in Magic: The Gathering, which state that a player can only find and collect the cards that are physically present and eligible to be searched for. The intent is to allow the player to take the specific actions allowed by game mechanics without penalizing them for the absence of cards. Thus, retrieving the cards that are available reflects the actual circumstances within the game and allows the player to proceed appropriately.

In contrast, other options suggest actions that do not align with the game's rules regarding searches—such as the player being required to find all requested cards or not finding any at all. Those would not apply because the emphasis is on the cards that exist within the game state, rather than an expectation to meet the exact numbers requested.
