Split second (As long as this spell is on the stack, players can't cast spells or activate abilities that aren't mana abilities.)
Choose target card in a graveyard other than a basic land card. Search its owner's graveyard, hand, and library for all cards with the same name as that card and exile them. Then that player shuffles.

8 rulings from Wizards of the Coast
- 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.
- 19 March 2021Players may turn face-down creatures face up while a spell with split second is on the stack.
- 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.
- 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.
- 19 March 2021You don't have to find and exile cards with the same name as the target card in its owner's hand or library if you don't want to, but you do have to exile the cards from the player's graveyard.
- 19 March 2021Because the first step of casting a spell is to move it from the zone it's in, Extirpate can't be used to stop a spell with flashback from being cast after its controller has announced that they're casting it.
- 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.
- 19 March 2021Casting a spell with split second won't affect spells and abilities that are already on the stack.
