Malicious Malfunction

• WWizards of the Coast2022-02-18
  Official Ruling
  Creatures that would die for any reason this turn are exiled instead, not just creatures that would die after getting -2/-2.
• WWizards of the Coast2022-02-18
  Official Ruling
  While the -2/-2 applies only to creatures that are on the battlefield as Malicious Malfunction resolves, the replacement effect applies to all creatures that turn, including ones that enter the battlefield after Malicious Malfunction resolves or noncreatures that become creatures after Malicious Malfunction resolves.
