Eternal Agony

Whenever a creature an opponent controls
would die, It instead gains two -1/-1 counters
and becomes indestructible until the beginning
of its controllers next upkeep. Its controller loses
2 life.
{b}: Put a -1/-1 counter on target creature.
"I don't want you to die, I want you to suffer" -
Nefti, Pact Master.
