Devour Flesh, Tenacious Dead, Blistergrub and mind rot is to keep you alive untill extraplanar lens, sanguine bond, liliana of the dark realms are out to go for the kill with consume spirit, tendrils of corruption and exsanguinate.Elixer of immortality is kind of to reuse your cards that are in your graveyard, also to get some lifegain and do some dammage when sanguine bond is out. Thinking of adding exquisite blood in there to get the infamous sanguine bond + exquisite blood combo.

Let me know what you think, any help is appreciated!!
