4 rulings from Wizards of the Coast
- 29 September 2017You can reveal the same Dinosaur card for multiple Priests of the Wakening Sun or for the same one over multiple turns.
- 29 September 2017While resolving Priest of the Wakening Sun’s triggered ability, you can’t reveal multiple Dinosaur cards to gain more life.
- 29 September 2017You don’t choose whether to reveal a Dinosaur card from your hand until the triggered ability of Priest of the Wakening Sun resolves. You may respond to the triggered ability by taking an action to get a Dinosaur card into your hand, such as activating its second ability.
- 19 January 2018If an effect refers to a “[subtype] spell” or “[subtype] card,” it refers only to a spell or card that has that subtype. For example, March of the Drowned is a card that benefits Pirates and features Pirates in its illustration, but it isn’t a Pirate card.
