Arvad the Cursed: Deathtouch, lifelink, and +2/+2 for legendary creatures - Edgar approves!
Bishop of Binding: Exile a creature (hello indestructible ones) and add to a vampire its power - sounds good to me!
Bishop of Rebirth: You lost a <= 3 CMC vampire? No problem, get it back during your combat step!
Bishop of the Bloodstained: You have many vampires - good, cast this one and see the life points of a target opponent go down! What is even weirder - use some kind of sacrifice/return (see below) mechanism and subdue your fellow players!
Blood Baron of Vizkopa: Holy - lifelink, protection from white and from black and +6/+6 in potential mid- to endgame!
Blood-Cursed Knight: A potential 4/3 with lifelink for 3 CMC - I like that!
Bloodhusk Ritualist: You have some spare untapped swamps? - Let somebody discard his/her entire hand!
Bloodline Keeper
: Do you think Edgar is the only vampire token machine in this set-up? What about some 2/2 tokens WITH flying?!
Bloodline Necromancer: Lifelink + bring back one fellow bloodsucker!
Bloodsworn Steward: Do you remember Arvad the Cursed? This is one is only for our beloved Edgar!
Bloodtracker: Some spare untapped swamps and many life poins? Pump him up, and when he dies - draw some cards!
Butcher of Malakir: There is no way to say "I love you" in commander other than to let your fellow players sacrifice creatures. <3
Crimson Honor Guard: 4 damage each turn to your fellow players while Edgar is chilling on the battlefield with some hot blood tea - cool!
Defiant Bloodlord: Lifelink is cool, but share your happiness with a fellow player and let his/her life points crumble. ;-)
Drana's Emissary: Flying, life gain to us, life loss to the others - everything is ok!
Drana, Kalastria Bloodchief: Bye, bye indestructible creatures! <3
Drana, Liberator of Malakir: Hooh boy, +1/+1 every time combat damage dealt is to a player? Vampire madness is real!
Elenda, the Dusk Rose: Creatures die, Elanda rises - and when she falls, she will leave some vampire tokens WITH lifelink!
Falkenrath Exterminator: The second ability can be good, but combat damage to player with this one? I have to look.....
Falkenrath Marauders: Flying, haste and +2/+2 when combat damage dealt to player? This creature can get pretty big when left alone!
Gatekeeper of Malakir: The kicker ability is ok.
Griselbrand: Just for card drawing, but when effectively used can get you a net win/loss of 0 life points.
Havengul Vampire: If you can't deal combat damage to a player - don't worry, this one pumps up when everbody is dying around him. ;-)
Kalastria Highborn: Hmm.... for a 2/2 with a little punishing effect - this is ok.
Kalastria Nightwatch: You gain life, this guys gains flying - sounds fair to me. ;-)
Kalitas, Bloodchief of Ghet: Wow - destroy a target creature and create a 'copy' token of it - nice!
Kalitas, Traitor of Ghet: Exile target creatures leaving the battlefield and generate 2/2 zombie tokens + pump up ability - cool!
Kazarov, Sengir Pureblood: We have some vampires dealing damage to players - this one is profiting from it in the form of +1/+1 counters.
Kheru Bloodsucker: More life gain for us, life loss for the others, and pump up ability - cool!
Licia, Sanguine Tribune: Crazy vampire which can get very big very fast!
Mephidross Vampire: "Who wants to be a (strong) vampire?" No problem using this creature.
Mirror Entity: Depending on the board state, this creature can potentially lead to your win. Have many vampires and tokens, make them strong and swing in.
Necropolis Regent: If you have some creatures with protection/menace or any other ability which lets you deal direct combat damage to a player - the attacking creature can get pretty big very fast!
Nirkana Assassin: You gain life, this one gets deathtouch.
Nirkana Revenant: As you can see, many vampires are black creatures - since you will have many swamps, this card is a great source.
Patron of the Vein: Just read the text - a must have!
Patron of the Vein card text Show
Flying
When Patron of the Vein enters the battlefield, destroy target creature an opponent controls.
Whenever a creature an opponent controls dies, exile it and put a +1/+1 counter on each Vampire you control.
Regal Bloodlord: Since many vampires can let you gain life points via lifelink or other static abilities, this one generates bat tokens at each end step when life is gained. A possible card combination/combo is described below.
Vampire Champion: Deathtouch, nothing special.
Vampire Nocturnus: Potential +2/+1 AND flying for every vampire on the battlefield!
Vengeant Vampire: "You killed me? Give me one of your creatures (and some life points) and we're even, buddy." :-D
Vish Kal, Blood Arbiter: "Too many vampire on the battlefield?" Sacrifice them for a better cause. ;-)
Vona, Butcher of Magan: "Too many life points? Let us exile some cards so that our fellow player get a chance of winning." ;-)
