5 rulings from Wizards of the Coast
- 14 July 2017An ability that triggers when something "attacks and isn't blocked" triggers in the declare blockers step after blockers are declared if (1) that creature is attacking and (2) no creatures are declared to block it. It will trigger even if that creature was put onto the battlefield attacking rather than having been declared as an attacker in the declare attackers step.
- 14 July 2017Afflict resolves before combat damage is dealt. If this loss of life brings a player to 0 life or less, that player loses the game immediately. A blocking creature with lifelink won't deal combat damage in time to save that player.
- 14 July 2017Afflict causes the defending player to lose life; it's not damage or combat damage.
- 14 July 2017If multiple creatures block a creature with afflict, afflict triggers only once.
- 28 July 2023If a creature is attacking a planeswalker, that planeswalker's controller is the defending player. If a creature is attacking a battle, that battle's protector is the defending player.
