What to cut, what to add, and how to play the Rakdos Vampire precon from Innistrad: Crimson Vow, commanded by Strefan, Maurer Progenitor.

Innistrad: Crimson Vow
Vampiric Bloodline
Blood tokens filter into whatever the hand needs. Out of the box, before any upgrades. How we rate precons
Buy Vampiric Bloodline on TCGplayer →Vampiric Bloodline is a focused Vampire deck with plenty of ways to drain the table and a commander that turns that drain into free creatures. Strefan, Maurer Progenitor makes a Blood token at your end step for every player who lost life that turn, and when it attacks it can trade two of them to put a Vampire from your hand onto the battlefield attacking. The weak spots are a slow early game, with few cheap Vampires that cause life loss on their own, and a mana base and set of rocks that enter tapped too often.
TurnZero HQ rates Vampiric Bloodline a 3 out of 5 on difficulty and a 3 out of 5 on power, as it comes in the box. That is our editorial read, not an official Wizards rating. The full hundred cards are on the Vampiric Bloodline decklist page, and every other precon we cover is on the precon directory.
Strefan, Maurer Progenitor is a four-mana 3/2 flier. At the beginning of your end step, you create a Blood token for each player who lost life that turn, and that includes you. Whenever Strefan attacks, you may sacrifice two Blood tokens to put a Vampire card from your hand onto the battlefield tapped and attacking, and it gains indestructible until end of turn. A Blood token can also be spent on its own to discard a card and draw one.
The deck feeds Strefan by draining. Sanctum Seeker drains each opponent whenever a Vampire attacks, Blood Artist and Falkenrath Noble drain when creatures die, and cards like Night's Whisper and Damnable Pact make you lose life too, which still counts. With Blood tokens stocked up, Strefan can put Necropolis Regent , Butcher of Malakir or Vampiric Dragon onto the battlefield for two tokens instead of six or more mana.
There is also a madness subtheme. Falkenrath Gorger gives every Vampire card you own madness, so discarding one to a Blood token lets you cast it for its normal cost from exile. Glass-Cast Heart makes a Blood token each time your Vampires attack and can eventually cash thirteen of them in for a huge drain.
Strefan, Maurer Progenitor ↗
Makes Blood tokens from any life loss and turns two of them into a free Vampire attacking with indestructible. The deck's expensive Vampires cost nothing once it is online.
Sanctum Seeker ↗
Each Vampire that attacks drains each opponent for 1. With a few attackers out, every opponent loses life every turn, so Strefan makes a Blood token for each of them.
Crossway Troublemakers ↗
Gives attacking Vampires deathtouch and lifelink, and lets you pay 2 life to draw whenever a Vampire dies. Attacking becomes safe and profitable.
Bloodsworn Steward ↗
Gives Strefan +2/+2 and haste, so it can attack and use its Blood tokens the turn it comes down.
Blood Artist ↗
A cheap drain whenever any creature dies. It makes sure someone loses life most turns, which is all Strefan needs.
Necropolis Regent ↗
Your creatures get +1/+1 counters equal to the combat damage they deal to a player. Put in by Strefan, it starts working that same combat.
The curve starts slow. Most of the Vampires that drain cost four or more, and two-drops like Cordial Vampire and Stromkirk Condemned don't make anyone lose life on their own. On the turns before Strefan lands, the deck often has nothing to cause the life loss its commander turns into Blood.
The mana is clunky for a two-color deck. Charcoal Diamond and Fire Diamond enter tapped, Unstable Obelisk costs three for one colorless, and lands like Temple of the False God and Myriad Landscape slow the early turns. A few slots also go to cards that don't fit the Vampire plan, like Laurine, the Diversion , a Human that Strefan can't put onto the battlefield.
Each upgrade below starts from something the deck does poorly and says what a replacement card has to do. The cards named are examples, not the only answer: if you own something else that does the same job, or a newer printing does it better, it goes in the same slot. Make one change at a time and play a few games between them, so you can tell which change helped. The general method is in how to upgrade a Commander precon →
Strefan only makes Blood when someone loses life. Two- and three-mana Vampires that cause life loss on their own mean the tokens start piling up from the first end step it is on the battlefield.
What to look for Vampires costing three mana or less that drain, or that turn your lifegain into an opponent's life loss.
Cut, for example
Laurine, the Diversion Not a Vampire, so Strefan can't use it, and its goad needs you to sacrifice an artifact or creature each time.
Crimson Honor Guard Deals 4 damage at each end step only to a player who doesn't control a commander. Most of the time nobody qualifies, and once Strefan dies it can be you.
Add, for example
Vito, Thorn of the Dusk Rose ↗
Three mana: whenever you gain life, a target opponent loses that much. The deck's many lifelink creatures turn into a drain.
Kalastria Highborn ↗
Whenever it or another Vampire you control dies, you may pay {B} to make a player lose 2 life and gain 2 yourself.
Vampire Socialite ↗
Two mana with menace. If an opponent lost life this turn, your other Vampires get +1/+1 counters when it enters and every later Vampire enters with an extra counter.
The deck already plays Blood Artist , Falkenrath Noble and Timothar, Baron of Bats , but has few free ways to sacrifice a creature on your own terms. A sacrifice outlet and another death payoff make every chump block and removal spell drain the table.
What to look for Free sacrifice outlets that are Vampires, or Vampires that drain whenever any creature dies.
Cut, for example
Midnight Arsonist Only destroys artifacts without mana abilities, which many tables barely have. It is often a 3/2 for four.
Imposing Grandeur Lets every player discard their hand and draw cards equal to their commander's mana value. It helps whoever has the biggest commander as much as you.
Add, for example
Viscera Seer ↗
A one-mana Vampire that sacrifices a creature for free and scries 1. It turns Blood Artist and Falkenrath Noble on whenever you want.
Vein Ripper ↗
Whenever any creature dies, a target opponent loses 2 life and you gain 2. Its ward makes opponents sacrifice a creature to target it, and Strefan can put it in for two Blood tokens.
Two diamonds that enter tapped and a three-mana colorless rock slow down a deck that wants Strefan on turn three. Two-mana rocks that are ready to use the turn you play them fix that.
What to look for Two-mana mana rocks that enter untapped and make black or red, or that turn into a card later. The mana rocks guide has more options.
Cut, for example
Charcoal Diamond Enters tapped and makes only black, so it doesn't speed up the next turn the way an untapped rock does.
Fire Diamond The red version, with the same problem of entering tapped.
Unstable Obelisk Three mana for one colorless mana. Its removal mode costs seven more and a sacrifice.
Add, for example
Talisman of Indulgence ↗
Two mana, enters untapped, and taps for black or red at the cost of 1 damage. That damage also counts as you losing life for Strefan.
Mind Stone ↗
Two mana for one colorless, and you can sacrifice it later to draw a card when you no longer need the mana.
Fellwar Stone ↗
Two mana, enters untapped, and taps for any color an opponent's lands could make, which almost always includes black or red.
Several lands enter tapped or make only colorless, which hurts most on the turns you want to cast a two-drop and hold up mana. Untapped Rakdos duals keep the early curve on time.
What to look for Black-red dual lands that usually enter untapped. See the land and mana base guide for how many to run.
Cut, for example
Temple of the False God Makes no mana until you control five lands, so it is a blank early.
Myriad Landscape Enters tapped and needs two more mana and a sacrifice to fetch lands that also enter tapped.
Add, for example
Dragonskull Summit ↗
Taps for black or red and enters untapped if you control a Swamp or a Mountain.
Sulfurous Springs ↗
Always enters untapped. Tapping it for colored mana costs 1 life, which Strefan counts at your end step.
Haunted Ridge ↗
Taps for black or red and enters untapped once you control two other lands.
The upgraded deck wins by draining. Cheap Vampires like Vito, Thorn of the Dusk Rose and Sanctum Seeker make the table lose life every turn, Strefan turns that into Blood tokens, and the tokens put Vein Ripper , Butcher of Malakir or Necropolis Regent onto the battlefield attacking. Death triggers from Blood Artist and friends finish the last few points, and Glass-Cast Heart can end a long game on its own.
A good pick for someone who likes typal decks with a clear plan and is happy to track Blood tokens. Strefan asks you to decide each turn whether to spend tokens on a free Vampire or on card filtering, which is a moderate amount to think about. It suits players who like attacking and draining rather than heavy interaction.
