Carte Magic New Blood

New Blood is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

01

Official card text

As an additional cost to cast this spell, tap an untapped Vampire you control. Gain control of target creature. Change the text of that creature by replacing all instances of one creature type with Vampire.

Complete guide

New Blood is a unique sorcery from the Commander 2017 series that allows Vampire decks to steal their opponents' best threats. Not only do you gain control of a creature, but you also rewrite its very nature to serve your bloodthirsty ranks. This spell is a powerful tool for turning an opponent's tribal synergy against them.

What It Does

New Blood is a control-magic style spell with a tribal twist. As an additional cost to cast it, you must tap an untapped Vampire you control. Upon resolution, you gain permanent control of a target creature and choose one creature type mentioned on that card (either in its type line or its rules text) to be replaced with the word Vampire.

How It Resolves Step by Step

First, when you cast the spell, you tap your Vampire and choose a target creature. Once the spell resolves, you gain control of that creature. At this moment, you choose a single creature type to replace. This change affects every instance of that word on the card, including the type line and the ability text. For example, if you change 'Human' to 'Vampire', a 'Human Soldier' becomes a 'Vampire Soldier'.

Common Mistakes

A frequent error is trying to change a word that isn't a creature type, such as 'Artifact' or 'Enchantment'; you must choose a valid creature type. Additionally, remember that New Blood only changes the text printed on the card or defined by its underlying object. It cannot change creature types mentioned in abilities granted by other cards, such as equipment or auras.

When to Play It

You should play New Blood when your opponent has a creature that provides powerful 'Lord' effects or tribal synergies. Because the control effect is permanent and the text change lasts as long as the creature is on the battlefield, it is ideal for stealing a commander that pumps up its own tribe, allowing it to pump your Vampires instead.

Interaction examples

Sacrificing the Stolen Prize

After you have used New Blood to gain control of an opponent's creature, you can use Victimize to sacrifice that stolen creature as a cost. This allows you to remove the threat permanently from their side while returning two of your own Vampires from your graveyard to the battlefield.

Clearing the Board After Theft

If you use New Blood to steal a creature and then realize the board state is still too dangerous, you can cast Toxic Deluge. Since you now control the stolen creature, it will be affected by the -X/-X along with everything else, but this can be a strategic way to ensure you are the only one left with a board presence if your stolen creature has high toughness.

How it works : New Blood

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    To pay the additional cost of New Blood, you may tap any untapped Vampire you control, including one you haven't controlled continuously since the beginning of your most recent turn. (Note that tapping the creature doesn't use {T} [the tap symbol].)

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    New Blood changes the creature type each time it appears in the creature's type line and/or rules text. It doesn't change the name of the card or any instances of the word being used as part of a card's name.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    You choose what word you're changing as New Blood resolves. You don't have to choose a word that appears in the creature's text.

    No other card is named in this ruling.

  4. #4· Wizards of the Coast

    The creature you gain control of won't be a Vampire if you don't choose a creature type in that creature's type line as one to replace.

    No other card is named in this ruling.

  5. #5· Wizards of the Coast

    New Blood's effect changes only the text printed on the creature. It can't change words found in abilities it's been granted. For example, if you change Rat to Vampire on Hungry Lynx, your Cats will have protection from Vampires; but if instead you change Rat to Vampire on Phantom Nishoba while you control a Hungry Lynx, Phantom Nishoba will have protection from Rats.

    No other card is named in this ruling.

  6. #6· Wizards of the Coast

    The type-changing effect can change part of a word (such as "non-Human") if the part of the word is being used to refer to a creature type.

    No other card is named in this ruling.

  7. #7· Wizards of the Coast

    You must choose an existing creature type, such as Vampire or Cat. Card types such as "artifact" can't be chosen.

    No other card is named in this ruling.

  8. #8· Wizards of the Coast

    You can't choose multiple creature types, such as "Cat Warrior." A Cat Warrior is both a Cat and a Warrior. It's affected by anything that affects either type and unaffected by things that affect non-Cat or non-Warrior creatures.

    No other card is named in this ruling.
