Trample, indestructible
You may pay 6 life and sacrifice 3 creatures with
power 4 or greater rather than pay Eater of
Worlds's mana cost.

At the beginning of your upkeep, pay {2} or put 2
-1/-1 counters on each creature you control.
Whenever an opponent gains life, that player
loses that much life instead.
