Yawgmoth, Flesh Bane

When Yawgmoth, Flesh Bane enters the battlefield, put X -1-1 counters on each other creature, where X is half the amount of life you
paid to cast this spell.
Whenever a creature dies, if it had a -1-1 counter on it, create a 1/1 colorless Phyrexian artifact creature token with infect.
"The greatest sin in life is ignoring death's embrace."
