Carte Magic Land Equilibrium

Land Equilibrium 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

If an opponent who controls at least as many lands as you do would put a land onto the battlefield, that player instead puts that land onto the battlefield then sacrifices a land of their choice.

Complete guide

Land Equilibrium is a classic blue enchantment that punishes opponents for ramping or trying to keep up with your land count. It creates a restrictive environment where your opponents are effectively capped at the number of lands you currently control. This card is a staple for control decks looking to lock down the board early and prevent opponents from establishing a resource advantage.

What It Does

Land Equilibrium establishes a replacement effect that monitors how many lands your opponents have compared to you. If an opponent attempts to put a land onto the battlefield while they already control as many lands as you—or more—they are forced to sacrifice a land immediately. This applies to lands played normally as the turn action and lands put into play via spells or abilities.

How It Resolves Step by Step

First, the game checks the current land count as a land is about to enter the battlefield. If the opponent meets the condition (controlling at least as many lands as you), the replacement effect triggers. The land enters the battlefield, and then the opponent must choose and sacrifice a land they control. Note that they can choose to sacrifice the land that just entered, but they cannot tap it for mana first, as the sacrifice happens immediately as part of the resolution of the entry.

Common Mistakes

A frequent error is thinking this prevents the land from entering; it does not. The land actually hits the battlefield before the sacrifice occurs. Another mistake is assuming this only affects 'played' lands. It actually affects any effect that puts a land onto the battlefield, regardless of who will eventually control it. If your opponent is the one putting it there, they are the one who must sacrifice a land.

When to Play It

This card is most effective when you have a low land count or a way to bounce your own lands. It is a powerful tool to pair with tax effects that make spells expensive, as it prevents opponents from ever gaining the mana base required to pay those taxes.

Interaction examples

Stalling the Resource Race

With Land Equilibrium on the field and you at three lands, your opponent cannot increase their land count beyond two without sacrificing. This makes Rhystic Study significantly more powerful, as the opponent will struggle to find the extra mana to pay the tax for their spells, ensuring you draw more cards.

Building a Mana Fortress

If you control four lands and your opponent controls four, every time they try to play a fifth land, they must sacrifice one. This keeps their available mana static. Combined with Propaganda, the opponent may never reach the mana threshold needed to both play spells and pay the attack costs, effectively shutting down their combat phase.

How it works : Land Equilibrium

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    This effect applies no matter how the land would enter: because an opponent plays it, or because a spell or ability allows that opponent to put it onto the battlefield. Note that it doesn't matter under whose control the land enters. If the opponent would put the land onto the battlefield under someone else's control (as a result of Yavimaya Dryad's ability, for example), that opponent will still have to sacrifice a land.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    If an opponent puts a land onto the battlefield under their own control, they may sacrifice that same land. The player won't be able to tap that land for mana before sacrificing it.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    If a land that would enter has its own "If [this land] would enter" replacement effect, the player who will control that land chooses which replacement effect to apply. After applying one, if the other one would still be applicable, it's then applied.

    No other card is named in this ruling.
