Nyxcoil Wurm

Trample, Deathtouch
When Nyxcoil Wurm dies, put two 3/3 black Wurm creature tokens onto the battlefield with "When this creature enters the battlefield, vitiate 2." (A creature with Vitiate 2 enters the battlefield vitiating target creature an opponent controls. Whenever that creature deals or is dealt damage, it's controller loses 1 life.)
