The 3 combo pieces

What must be in place

"Saproling" chosen with Plague Engineer.

How to execute it

  1. Yavimaya causes all lands to be Forests in addition to their other types, thus Life and Limb causes all lands to be 1/1 Saproling creatures.
  2. Because Plague Engineer gives all Saprolings your opponents control -1/-1, they die as a state-based action due to having zero toughness.
  3. Whenever an opponent plays a land, it will also die as a state-based action.

What the combo produces
