Can a card that is revealed remain revealed for an extended time during an effect?

The correct answer indicates that a card can indeed remain revealed for as long as necessary, depending on the context of the game and the specific effect being applied. When a card is revealed, such as when a player uses an ability that calls for revealing a card from their hand, the game state allows that card to remain in a revealed state for the duration specified by the effect or until the conditions are met that cause it to stop being revealed.

In many instances, cards are revealed for a limited timeframe necessary to resolve certain effects, like when checking if a card meets criteria during a search or an effect that grants knowledge of what card is in another player's hand. As long as the game rules or the effect's instructions do not specify a time limit, the card remains revealed for as long as it is pertinent to the resolution of that effect.

This highlights how crucial the text of the card and the timing of effects are to the game state. It provides players with strategic options—both in terms of revealing cards to gather information and using those moments strategically to influence gameplay. In certain situations or sequences, revealed cards can be pivotal, thus maintaining their revealed state until the game necessitates their return to a hidden state.
