Crystal Keep Rulings Summaries

• If an instant or sorcery is played that would damage this creature, the instant or sorcery will go to the graveyard during its resolution prior to the check for lethal damage that occurs as a state-based effect. This means it is possible for the spell card to increase this creature's power/toughness prior to the check. [D'Angelo 2008/05/25]
