- 19 January 2018In a Two-Headed Giant game, the last ability of Forerunner of the Coalition causes the opposing team to lose 2 life.
- 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.
