Crystal Keep Rulings Summaries

• If used on a sorcery like Hurricane which does X damage to multiple targets, it will cause that player to take damage equal to the sum of all damage inflicted by the spell. Ouch! [Duelist Magazine #2, Page 9]
• Extended tournaments (see Rule 803) have always banned this card.
