Nurgle, Lord of Decay

Deathtouch, persist
Eminence— As long as Nurgle is in the command
zone or on the battlefield, creatures have "Pay 3
life: Regenerate."
At the beginning of each of your upkeeps, put a
-1/-1 counter on each other creature on the
battlefield. Then, each player loses 2 life.
Enemies and allies both will wither and die.
