For 1 life and a creature, Yawgmoth lets you draw a card and place a -1/-1 counter on another creature, providing a sacrifice outlet, card draw, and board control in one package
And make sure to catch me here every couple of weeks sharing my thoughts and insights into the Commander format

Like many Commander precons, where this deck does falter slightly is in its selection of lands
