~~~~~~~~~~~~~~Mana Rocks~~~~~~~~~~~~~~~~~
Mox Diamond / Lotus Petal - Really important to have these free ramp spells because if you start to draw your deck down very heavily, these free spells allow you that extra push
Pristine Talisman - very good when trying to get to an even life total, so if you have phyrexian unlife on the field you can make it to 0. You can also use it to go down to one and win with near death.
Sol Ring- Auto include in most every deck
Orzhov Signet - Some fixing and early ramp
Darksteel ingot - Keeps your mana on board if something happens
Thran dynamo - Solid include 4 mana for a rock that gives 3 colorless
Gilded Lotus - Helps mana fixing
~~~~~~~~~~~~~~~~~Draw ~~~~~~~~~~~~~
Syphon Mind - Not the best card on it's own, but it shines in a multiplayer format
Ambition's Cost - 4 mana for 3 cards, you're not really worried about losing life in this deck.
Necrologia - Instant speed card draw. Don't be afraid to pay life on this, but remember it's at end step so if you don't have a tower out you'll have to discard
Promise of Power - Just a very good card draw spell in black, also has the option of putting a demon on the field
Night's Whisper - a better sign in blood because it doesn't require the 2 black.
Necropotence - Amazing in a deck like this allowing us to search for combo peices and manipulate our life total at a moment's notice.
~~~~~~~~~~~~~~~~~~~~~Tutors ~~~~~~~~~~~~~~~
Enlightened tutor / Vampiric tutor/ Demonic tutor/ Idyllic Tutor/ Beseech the Queen - all very good tutors in our colors.
Academy rector - lets us block and search for enchantments
Liliana Vess - Normally she gets two tutors off for five mana, sadly she puts them on top but with sensei's it's basically a demonic tutor
~~~~~~~~~~~~~~~ Utility ~~~~~~~~~~~~~
Nihil spellbomb - better than a tormod's crypt because it allows us to draw a card.
Land tax - very good synergy with scroll rack and helps us hit land drops/fix.
Scroll rack - Awesome for fixing our draws and with land tax it's a free ancestral recall because we can put our lands on top, draw 3 cards and then shuffle them away with next time with land tax
Sensei's divining top - auto include in any deck, especially a combo deck
Yawgmoth's will - in case somebody destroys a critical combo piece.
Aura of silence - underplayed in my opinion, we can tutor this up off an academy rector. makes their spells cost more and we can sac it to destroy problem
enchantment/artifacts.
Replenish - returns all our enchantment cards to play
Return to Dust - one of the best spells for dealing with enchantments/artifacts
Beacon of Unrest - We mainly use this to return artifacts, but if your opponents have a rune-scarred demon we'll gladly take one.
Eternity Vessel - allows us to stabilize our life total, fetches make this card awesome.
Beacon of immortality - another way for us to stablize plus can kill people with sanguine bond in play.
Arbiter of Knollridge- keeps our life up high, as well as slows down any aggro player from killing people.
~~~~~~~~~~~~~~ Removal ~~~~~~~~~~~~~
Swords to plowshares - obvious inclusion
Path to exile - another, obvious inclusion
Go for the throat - I run this because my meta doesn't include a lot of artifact creatures.
Mortify - Kills creatures and pesky enchantments
Utter end - get rid of anything you don't like
Day of Judgement / wrath of god / Rout / Toxic Deluge / Hallowed Burial / Terminus - a variety of sweepers to hit any kind of board, we have anti regeneration, instant speed, tuck, and even -1/-1 counters
~~~~~~~~~~~~~~ Win Cons ~~~~~~~~~~~~~
Selenia + Children of Korlis / Tainted Sigil + sanguine bond / wound reflection - bring yourself down with selenia and then sac'ing a tainted sigil with one of the enchantments out can one shot sombody most of the time.
Selenia + Phyrexian Unlife + repay in kind = everybody goes to 0 and you win.
Selenia + Phyrexian Unlife + mirror universe/ Magus of the mirror / reverse the sands / soul conduit - put yourself to 0 and switch with somebody
Near-Death Experience - as long as you're at 1 life you win on your next upkeep. cards like Angel's grace help make sure you don't die.
Exsanguinate - you have cabal coffers and urborg, go to work.
Selenia + Hatred = most people let selenia through making her a one shot is very helpful.
pestilence / crypt rats - sometimes you can't always get down to 0. but getting down to 1 or 2 and using these finishes them off.
Angel's grace / phyrexian unlife + adnauseam - if you need to find that last card feel free to draw your deck, this lets you dig as far as you want. Phyrexian unlife gives you posion counters when you take damage, thankfully for us. damage and loss of life is different so we can go as far as we need with ad nauseam
