I am unfortunately not too familiar with your inventory, I am just suggesting what comes to mind here.

I will assume that this is a deck that you play with friends, and that you don't want to lose too many of them, so I will not suggest the Exquisite Blood + Sanguine Bond combo. However, since this is a lifedrain deck, you can just run Exquisite Blood.

Rhox Faithmender, Alhammarret's Archive, and Beacon of Immortality are nice life doublers. Purity, Debt to the Deathless, Kokusho, the Evening Star (why is he so pricey) and maybe, just maybe Vigil for the Lost and True Conviction (if this is an attacky deck) also increase the lifegain factor.

Some cards that reward you for gaining life are Test of Endurance, Felidar Sovereign, Ayli, Eternal Pilgrim, Karlov of the Ghost Council, Serra Ascendant (too f*cking pricey), Blood Baron of Vizkopa, Serra Avatar, Divinity of Pride, Rune-Tail, Kitsune Ascendant, Defiant Bloodlord, Ajani's Pridemate, Cliffhaven Vampire, Archangel of Thune (also too pricey), etc.

Some cards that gain you life are Soul Warden, Soul's Attendant, Martyr of Sands, Suture Priest, and Auriok Champion (also too f*cking pricey).

This last section I feel should be included, but if you don't want to, you don't have to. I feel that there should be some extent of active control in this deck, since lifegain decks tend to be slow. I would suggest Malicious Affliction, Tragic Slip, Victim of Night, Go for the Throat, Path to Exile, Swords to Plowshares, Thoughtseize, Inquisition of Kozilek, Transgress the Mind, etc. You can also throw in Blind Obedience, Painful Quandary, and Lightmine Field for more asshole control, or you can throw in a few boardwipes such as Languish, Wrath of God (will have to do for a Damnation substitute), and Magister of Worth.

Well, I hope this wall of text I just typed helped. Good luck with the deck, and may topdeck be ever in your favor.

Crap, I meant to say the lifedrainy one is Sanguine Bond, not Exquisite Blood. I mix them up very often, my bad.

i like the asshole control ideas you threw in there, especially Blind Obedience with it having extort on there. im almost kinda shocked that Test of Endurance and Felidar Sovereign are legal in commander, seems like an easy win with a deck with life gain, but what do i know, im still a nub when it comes to mtg even though i started playing like 15+ years ago :D

Nice list +1

What no Pontiff of Blight or Crypt Ghast Arguably 2 of the best creatures with extort.

Might find some fun stuff in God of Leaches

squirlfood, those two cards look awesome, unfortunately i dont have them :D. one day i may buy specific cards to round out my decks, but not any time soon D:. i very much appreciate the input though

Well teh_grimness they both come in the black commander 2014 set.

squirlfood there's a good chance my buddies who have a group card collection as well as smaller personal stash's might have em. Hopefully ill be able to play test the deck this weekend and go through their cards to try to swap some of these suggestions in. I'm pretty excited to try this incarnation of the deck out, it originally had obzedat as the commander, but I picked up larval and a few others from a booster draft we did a few weeks ago and rebuilt the deck from scratch after that :D
