Carte Magic Tezzeret's Gatebreaker

Tezzeret's Gatebreaker 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

When this artifact enters, look at the top five cards of your library. You may reveal a blue or artifact card from among them and put it into your hand. Put the rest on the bottom of your library in a random order. {5}{U}, {T}, Sacrifice this artifact: Creatures you control can't be blocked this turn.

Complete guide

Tezzeret's Gatebreaker is a versatile artifact that acts as both a precision tutor and a definitive finisher. By digging into your library and later ensuring your forces bypass all defenses, it bridges the gap between mid-game consistency and end-game victory.

Finding Your Pieces

When Tezzeret's Gatebreaker enters the battlefield, you look at the top five cards of your library. You can choose any one blue card or any one artifact card (including artifact creatures) from those five to put into your hand. This helps you maintain card advantage while setting up your next big play.

Clearing the Path

The second ability is a powerful utility that costs six mana and requires sacrificing the artifact. Once activated, it creates a continuous effect for the remainder of the turn. Unlike many effects that only target creatures currently on the battlefield, this ability creates a rule for the turn that applies to all creatures you control, even those that enter the battlefield after the ability has resolved.

Timing and Strategy

Since the unblockable effect lasts until the end of the turn, you should typically activate it during your Precombat Main Phase or at the start of the Combat Phase. Remember that once a creature is legally blocked, making it unblockable afterwards will not remove the blocker or allow the damage to go through to the player.

Interaction examples

Digging for Utility

You cast Tezzeret's Gatebreaker. Upon entering, you look at your top five cards and see a Solemn Simulacrum. Since the Simulacrum is an artifact creature, it qualifies for the reveal. You put it into your hand to ensure your next turn's land drop and creature presence.

Mana Fix and Finish

You have both artifacts on the battlefield. You tap Commander's Sphere for blue mana to help pay the activation cost of the Gatebreaker. You sacrifice the Gatebreaker, and for the rest of the turn, all your creatures are unblockable. If you then sacrifice the Sphere to draw a card and find a haste creature, that new creature will also be unblockable when it attacks.

How it works : Tezzeret's Gatebreaker

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    Because the last ability of Tezzeret’s Gatebreaker doesn’t change the characteristics of any permanents, the set of creatures affected by it is constantly updated. Creatures that come under your control later in the turn can’t be blocked.

    No other card is named in this ruling.
