7 rulings from Wizards of the Coast
  1. 19 March 2021If 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.
  2. 19 March 2021After a spell with split second resolves (or otherwise leaves the stack), players may again cast spells and activate abilities before the next object on the stack resolves.
  3. 19 March 2021Because damage remains marked on a creature until the damage is removed as the turn ends, nonlethal damage dealt to a white creature may become lethal if Celestial Crusader leaves the battlefield during that turn.
  4. 19 March 2021Split second doesn't stop triggered abilities from triggering, such as that of Chalice of the Void. If one does, its controller puts it on the stack and chooses targets for it, if any. Those abilities will resolve as normal.
  5. 19 March 2021Players still get priority while a card with split second is on the stack; their options are just limited to mana abilities and certain special actions.
  6. 19 March 2021Players may turn face-down creatures face up while a spell with split second is on the stack.
  7. 19 March 2021Casting a spell with split second won't affect spells and abilities that are already on the stack.
