Maliketh, the Black Blade

Deathtouch, menace, haste
Maliketh, the Black Blade enters the battlefield with X +1/+1 counters, where X is the number of death counters removed from Gurranq, the Death Eater.
Whenever a creature an opponent controls dies, exile it, then deal damage to its controller equal to the number of creatures they own in exile.
"O, death... become my blade once more."
