Carte Magic Scheming Silvertongue // Sign in Blood

Scheming Silvertongue // Sign in 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

Flying, lifelink At the beginning of your second main phase, if you gained 2 or more life this turn, this creature becomes prepared. (While it's prepared, you may cast a copy of its spell. Doing so unprepares it.) Target player draws two cards and loses 2 life.

Complete guide

Scheming Silvertongue is a versatile Vampire Warlock that bridges the gap between early-game aggression and late-game card advantage. By leveraging its lifelink ability, you can unlock a free-to-cast copy of the classic Sign in Blood, turning your health gains into a powerful grip of cards.

Understanding Preparation

Scheming Silvertongue features the 'prepared' mechanic. At the start of your second main phase, the game checks if you have gained 2 or more life during the turn. If you have, this creature becomes prepared. When a creature becomes prepared, a copy of its associated spell—in this case, Sign in Blood—is created in exile. You may cast this copy from exile as long as the creature remains on the battlefield and prepared. Once you cast the spell, the creature becomes 'unprepared' and the copy is removed from exile.

How it Resolves Step by Step

First, ensure you gain at least 2 life during your turn, typically by attacking with Scheming Silvertongue during your combat phase. As your post-combat main phase begins, the ability checks the life gain condition and triggers. Once the trigger resolves, the creature is marked as 'prepared' and the Sign in Blood copy appears in exile. You may then cast that copy by paying its mana cost ({B}{B}) during that main phase or a future turn, provided the creature stays in play. As soon as you finish casting the spell, the 'prepared' status is removed.

Timing and Common Mistakes

A critical detail is that the ability triggers at the very beginning of your second main phase. You cannot enter your second main phase, then gain life, and expect the ability to trigger; the life must be gained before that phase starts. Additionally, a creature cannot be 'double prepared.' If it is already prepared, the trigger won't grant you a second copy of the spell. Lastly, remember that even if the creature loses its abilities later, it remains prepared until you cast the spell or it leaves the battlefield.

When to Play It

This card is most effective in decks that can reliably trigger its life gain condition. Because it has flying and lifelink, it can often trigger itself by attacking. It serves as a great bridge in midrange strategies, providing a relevant 2-power flyer that threatens to refill your hand if left unanswered.

Interaction examples

Self-Sufficient Preparation

You attack an opponent with Scheming Silvertongue. Since it has 2 power and lifelink, dealing damage causes you to gain 2 life. At the start of your second main phase, the ability checks your life gain, sees you gained exactly 2 life, and makes the creature prepared, giving you access to Sign in Blood.

Strategic Deaths

If your Scheming Silvertongue cannot safely attack, you can use other sources. If your Ornithopter of Paradise dies while Blood Artist is on the battlefield, Blood Artist's ability triggers, causing an opponent to lose 1 life and you to gain 1 life. If another creature dies the same turn, you reach the 2-life threshold, allowing Scheming Silvertongue to become prepared at the start of your next second main phase.

Casting the Copy

Once Scheming Silvertongue is prepared, you have a copy of Sign in Blood in exile. To cast it, you need {B}{B}. You can tap Ornithopter of Paradise for one black mana and use another land for the second black mana. Once you cast the copy, Scheming Silvertongue is no longer prepared. If you gain 2 more life on a subsequent turn, it can become prepared again.

How it works : Scheming Silvertongue // Sign in Blood

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    A preparation card is a creature card in every zone. For example, while it's in your graveyard, Emeritus of Ideation is a blue creature whose mana value is 5. It can't be the target of Zealous Lorecaster's triggered ability ("When this creature enters, return target instant or sorcery card from your graveyard to your hand.").

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    A creature with a prepare spell can't become prepared more than once at the same time. For example, Emeritus of Ideation is on the battlefield and is prepared. When it attacks, its last ability triggers. When that ability resolves, its controller may still exile eight cards from their graveyard, but doing so won't cause Emeritus of Ideation to become prepared a second time or create a second copy of Ancestral Recall in exile.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    Scheming Silvertongue's last ability will check as your second main phase starts to see if you gained 2 or more life this turn. If you didn't, the ability won't trigger at all. It's not possible to gain life during your second main phase in time to have the ability trigger.

    No other card is named in this ruling.

  4. #4· Wizards of the Coast

    Being prepared isn't a copiable value. If a permanent becomes a copy of a prepared creature, it won't be prepared. That permanent will have the alternative characteristics, though, and some other effect could cause it to become prepared later.

    No other card is named in this ruling.

  5. #5· Wizards of the Coast

    If an effect instructs you to choose a card name, you may choose the alternative prepare spell's name. Consider only the alternative characteristics to determine whether that is an appropriate name to choose.

    No other card is named in this ruling.

  6. #6· Wizards of the Coast

    As an effect causes a creature with a prepare spell to become prepared (including effects that state that a creature "enters prepared"), that creature's controller creates a copy of that creature's prepare spell in exile. That copy remains in exile for as long as that permanent is on the battlefield and is prepared. That creature's controller may cast that copy as long as it remains in exile. As they cast it, that creature stops being prepared.

    No other card is named in this ruling.

  7. #7· Wizards of the Coast

    Casting a copy of a prepare spell from exile isn't casting it for an alternative cost. Effects that allow you to cast a spell for an alternative cost or without paying its mana cost may allow you to apply those to a copy of a prepare spell cast from exile.

    No other card is named in this ruling.

  8. #8· Wizards of the Coast

    Preparation cards can only be cast with their base characteristics.

    No other card is named in this ruling.

  9. #9· Wizards of the Coast

    If a prepared creature stops being a creature, it will still be prepared, and the copy of its prepare spell will remain in exile. That permanent's controller will still be able to cast it. The same is true if a prepared creature becomes a copy of something else, even if it's then a permanent without a prepare spell.

    No other card is named in this ruling.

  10. #10· Wizards of the Coast

    While copies of spells in zones other than the stack cease to exist when state-based actions are checked, this does not apply to copies of prepare spells in exile that were created as a creature became prepared.

    No other card is named in this ruling.

  11. #11· Wizards of the Coast

    If a prepare spell with one or more targets has no legal targets when it tries to resolve, it won't resolve and none of its effects will happen. Since the spell was cast, the associated permanent will still not be prepared.

    No other card is named in this ruling.

  12. #12· Wizards of the Coast

    If a prepared creature loses all abilities, it won't stop being prepared, and nothing will happen to its alternative characteristics or to the copy of its prepare spell in exile.

    No other card is named in this ruling.

  13. #13· Wizards of the Coast

    A creature without a prepare spell can't become prepared.

    No other card is named in this ruling.

  14. #14· Wizards of the Coast

    Only the current controller of a prepared creature can cast the copy of its prepare spell in exile. It doesn't matter who owns that creature or who controlled it when it became prepared.

    No other card is named in this ruling.

  15. #15· Wizards of the Coast

    Creating a copy of a creature's prepare spell in exile ignores copy exceptions applied to that creature that would affect the copiable values of that spell. For example, say a player casts Croaking Counterpart (a sorcery that says "Create a token that's a copy of target non-Frog creature, except it's a 1/1 green Frog.") targeting Goblin Glasswright. The token copy of Goblin Glasswright will enter prepared as a 1/1 green Frog creature, but the copy of Craft with Pride in exile will still be a red sorcery. The copy of Craft with Pride won't be green, a creature, or a Frog, and it won't have power or toughness.

    No other card is named in this ruling.

  16. #16· Wizards of the Coast

    If an effect causes a creature to become unprepared, a prepared creature stops being prepared and the associated copy of its prepare spell in exile ceases to exist. If it wasn't prepared at that time, nothing happens.

    No other card is named in this ruling.
