Carte Magic Shadow of Doubt

Shadow of Doubt 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

({U/B} can be paid with either {U} or {B}.) Players can't search libraries this turn. Draw a card.

Complete guide

Shadow of Doubt is a powerful disruption tool that can shut down an opponent's deck-thinning strategies for a single turn. By preventing players from looking through libraries, it effectively turns common search effects into blank spells while keeping your own hand fresh.

What It Does

Shadow of Doubt creates a continuous effect for the remainder of the turn that forbids any player from searching libraries. Additionally, it provides card advantage by allowing you to draw a card immediately upon resolution, making it a 'cantrip' that replaces itself in your hand.

How It Resolves Step by Step

First, cast the spell using either blue or black mana. Once it resolves, the 'no searching' restriction takes effect instantly. Any search effect already on the stack—or any cast later in the turn—will fail to find cards. Finally, you draw a single card as the last part of its resolution.

Common Mistakes and Shuffling

A common point of confusion involves shuffling. If a card says 'Search your library... then shuffle,' the player must still shuffle their library even though no search occurred. However, if the card says 'You may search... If you do, shuffle,' the player cannot choose to search and therefore does not shuffle.

When to Play It

The best time to cast Shadow of Doubt is in response to a spell or ability that requires a search, such as a fetch land or a tutor. Since it stops all players, ensure you have already completed your own necessary searches for the turn before casting it.

Interaction examples

Protecting the Shadow

If you cast Shadow of Doubt to stop an opponent's search and they attempt to use Counterspell to stop you, the search will proceed normally if your spell is countered. You must ensure Shadow of Doubt resolves for the restriction to apply.

Offering a Trade

If you cast a search spell and your opponent responds with Shadow of Doubt, you could use An Offer You Can't Refuse to counter your own spell. While you lose the search, you would gain two Treasure tokens instead of simply letting the search fail under the Shadow's effect.

How it works : Shadow of Doubt

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    If an effect says "You may search your library . . . If you do, shuffle your library" or "You may search your library . . . then shuffle your library," you can't choose to search, so you won't shuffle.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    If an effect says "Search your library . . . then shuffle your library," you shuffle you libraries even though you can't search.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    Effects that instruct you to reveal or look at cards from the top of you library will still work. Only effects that use the word "search" are affected.

    No other card is named in this ruling.
