Nosth, the Rotweaver

Sacrifice a creature: Put a number of cards
equal to the sacrificed creatures toughness
from the top of your library into your graveyard.
Whenever a non-token Insect, Spider or Scorpion creature enters the battlefield under your control,
you may return target permanent card from your graveyard to your hand.
Without a doubt, she's the finest purveyor
of rancid meat and old carcasses you'll find in
all the Jade Moon.
