6 rulings from Wizards of the Coast
- 14 June 2019If you have less than 1 life and somehow haven't lost the game, damage dealt to you reduces your life total further below 0 (as normal).
- 14 June 2019In the Commander variant, combat damage you're dealt by a commander is still tracked, even if it doesn't change your life total.
- 14 June 2019Serra's emblem doesn't stop loss of life from effects that say that you lose life.
- 14 June 2019Serra's emblem doesn't prevent damage. It only changes the result of damage dealt to you. For example, a creature with lifelink that deals damage to you will still cause its controller to gain life, even if that damage would reduce your life total to less than 1.
- 14 June 2019In a Two-Headed Giant game, damage dealt to you and/or your teammate that would reduce your team's life total to less than 1 reduces it to 1 instead, as long as you control a creature. It doesn't matter whether your teammate controls a creature, even if they're the player being dealt damage
- 14 June 2019Serra's first ability affects only creatures you control with flying at the time it resolves. Creatures you begin to control later in the turn or that gain flying later in the turn won't get +1/+1.
