As Plague Engineer enters the battlefield, choose a creature type.
Creatures of the chosen type your opponents control get -1/-1.
The choice of creature type is made as Plague Engineer enters the battlefield. Players can’t respond to this choice. The -1/-1 effect starts applying immediately.
You must choose an existing creature type, such as Sliver or Warrior. Card types such as artifact, and supertypes such as legendary or snow, can’t be chosen.
