Rakdos, God of Despair

Haste, Indestructible
Whenever an opponent loses life, you may put
a 1/1 Pest creature token onto the battlefield.
{1}{b}{r},{t}: Target player loses 1 life equal
to the number of pests you control on the
battlefield.
He lets his minions do his dirty work, while
he sits back and waits. -Avacyn
