- Event card effects engage the game state at the time they resolve. If an event card creates a lasting effect on a set of cards, only cards that are in play at the time the event card is played are eligible to be affected. Cards that enter play after the resolution of the event are not affected by its lasting effect. (See Event Cards.) Additionally, if a Dragon character leaves or enters play later in the phase, it will not raise or lower the STR of any character that was affected by The Field of Fire.
