What about a tenacious dead, bubbling cauldron, and an ogre slumlord.
{Tenacious Dead}, {Bubbling Cauldron}, {Ogre Slumlord}
You can replace {bubbling cauldron} with {blood bairn} to make it more efficient, if wanted.
{Sanguine Bond} is another card that will play well with this combo. It'll make any creature sacrifice act as if it were a festering newt.
