11 rulings from Wizards of the Coast
- 14 July 2017If an opponent loses life but Neheb leaves the battlefield before your postcombat main phase begins, its last ability doesn't trigger.
- 14 July 2017Neheb's ability checks only how much life opponents lost during the turn, not by how much their life total decreased compared to the start of the turn. For example, if an opponent lost 2 life and then gained 8 life before your postcombat main phase, you'll add {R}{R}.
- 14 July 2017If multiple creatures block a creature with afflict, afflict triggers only once.
- 14 July 2017Afflict causes the defending player to lose life; it's not damage or combat damage.
- 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 2017You get a postcombat main phase even if no creatures attacked during a turn. Neheb's last ability will trigger.
- 14 July 2017Because it triggers at the beginning of a phase, Neheb's last ability isn't a mana ability. It uses the stack and can be countered by effects that interact with triggered abilities, such as that of Nimble Obstructionist.
- 14 July 2017If you somehow have more than two main phases in a turn, each main phase after your first one is a postcombat main phase, and Neheb's last ability triggers at the beginning of each of them.
- 14 July 2017If an opponent loses life and subsequently loses the game before your postcombat main phase, Neheb's last ability counts that loss of life.
- 14 July 2017Damage dealt to a player causes that player to lose that much life.
- 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.
