What infraction occurs when a player intentionally reveals a card she drafted to another player during a booster draft?

When a player intentionally reveals a card she drafted to another player during a booster draft, this scenario constitutes a Hidden Information Violation. This infraction arises because players in a booster draft are expected to keep the contents of their drafted card pool secret from their opponents until the draft is complete. Revealing a drafted card not only provides an unfair advantage or insight into the drafting strategy but also disrupts the integrity of the draft process, which relies on players making informed choices based on limited knowledge.

In tournaments and competitive play, the rules emphasize the importance of maintaining hidden information to ensure a fair and balanced environment. The action taken for this infraction typically involves a warning or other penalty depending on the circumstances, but the fundamental aspect is the violation of the expectation that players do not disclose information regarding their draft picks.
