Rulings:

• 5/1/2007 The delayed triggered ability will trigger regardless of whether any damage is actually prevented.
• 6/7/2013 Although originally printed with a characteristic-defining ability that defined its color, this card now has a color indicator. This color indicator can’t be affected by text-changing effects (such as the one created by Crystal Spray), although color-changing effects can still overwrite it.
