Forecast
Forecast is a special kind of activated ability that can be played only from a player’s hand. It’s written “Forecast – [Activated ability].” A forecast ability may be played only during the upkeep step of the card’s owner and only once each turn. The controller of the forecast ability reveals the card with that ability from his or her hand as the ability is played. That player plays with that card revealed in his or her hand until the upkeep step ends or until it leaves the player’s hand, whichever comes first.
