Standard deck based around Grimgrin, Corpse-Born I've been toying around with. Life loss through sacrificing Geralf's Messengers along with sacrificing Gravecrawlers to use Bone Splinters and Altar's Reaps.

Killing Wave as a good board clear as I'm usually ok with letting either all or all but one of my creatures die.

Blood Artist can leech some serious life and put the opponent in a bad position early on.
