2 rulings from Wizards of the Coast
- 7 June 2013Although 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.
- 19 March 2021If Summoner's Pact is countered, the delayed triggered ability that threatens you with a game loss won't trigger at the beginning of your next upkeep.
