Yavimaya, Cradle of Growth, Living Lands, and Elesh Norn, Grand Cenobite

Prerequisites

• Yavimaya, Cradle of Growth on the battlefield
• Living Lands on the battlefield
• Elesh Norn, Grand Cenobite on the battlefield

Steps

1. Yavimaya causes all lands to be Forests in addition to their other types, thus Living Lands causes all lands to be 1/1 creatures
2. Because Elesh Norn gives all creatures your opponents control -2/-2, they die as a state-based action due to having less than zero toughness
3. Whenever an opponent plays a land, it will also die as a state-based action

Results

• Destroy all lands opponents control
• Destroy any land that enters the battlefield under an opponent's control
