Lord of the Abyssal Gates

Menace, haste
Whenever a nontoken creature you control
would die, if it's toughness was greater than
zero, you may instead put a -1/-1 counter on it.
If you do, you lose life equal of the number of
-1/-1 counters on it. (It doesn't die.)
Whenever a creature you control dies, each
opponent loses life equal to the number of -1/-1
counters on it.
