  Angel's Grace 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.
• 2006-09-25
  After the effect wears off during the cleanup step, you'll lose the game if your total is 0 or less (or you have ten or more poison counters).
• 2006-09-25
  If your life total goes below 1, being dealt damage will not increase it back up to 1.
• 2006-09-25
  You can't pay more life than you have.
• 2006-09-25
  The last sentence applies only if your life total is being reduced by damage. Other effects or costs (such as "lose 1 life" or "pay 1 life") can reduce your life total below 1 as normal.

  Players still get priority while a card with split second is on the stack.
• 2013-06-07
  Split second doesn't prevent players from activating mana abilities.
• 2013-06-07
  Split second doesn't prevent triggered abilities from triggering. If one does, its controller puts it on the stack and chooses targets for it, if any. Those abilities will resolve as normal.
• 2013-06-07
  Split second doesn't prevent players from performing special actions. Notably, players may turn face-down creatures face up while a spell with split second is on the stack.
• 2013-06-07
  If the resolution of a triggered ability involves casting a spell, that spell can't be cast if a spell with split second is on the stack.
• 2013-06-07
  Casting a spell with split second won't affect spells and abilities that are already on the stack.
