Maliketh, the Black Blade

Destined Death—Whenever Maliketh deals
damage to an opponent, put a Death counter on
them. Whenever they gain life, subtract from
that gain how many Death counters they have.
Once there is ten Death counters on an opponent
they lose the game.
"O, Death. Become my blade, once more."
