NB : Rotting giant might be good again with some of the following cards (Liliana, Pox, Delve...); remove Stromgald crusader instead

//Look at the following cards :
Liliana of the Veil
Liliana, the Last Hope
Innocent blood (get rid of abyssal, dark confidant, can sac gravecrawler)
Murderous Cut (delve can be great with diregreaf and rotting)
Disfigure (small grasp)
Dismember (kind of cheap grasp, might be hard with confidant)
Smother (mid fatal push for one more, meh..)
Slaughter Pact (removal with trick)
Tragic Slip (tiny or huge grasp, fun)
Vendetta (kind of cheap non black removal, might be hard with confidant)
SmallPox
