Carte Magic Thawing Glaciers

Thawing Glaciers 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

This land enters tapped. {1}, {T}: Search your library for a basic land card, put that card onto the battlefield tapped, then shuffle. Return this land to its owner's hand at the beginning of the next cleanup step.

Complete guide

Thawing Glaciers is a classic utility land designed for long-term resource management and deck thinning. While it doesn't provide mana immediately, it ensures you never miss a land drop by repeatedly pulling basic lands from your library directly onto the battlefield.

Continuous Land Advantage

Thawing Glaciers enters the battlefield tapped, meaning it cannot be used the turn it is played. However, for a small investment of one generic mana and tapping the land, you search your library for any basic land card and put it onto the battlefield tapped. This effect allows you to accelerate your mana base over several turns, as the land you search for is an addition to your normal land drop for the turn.

The Cleanup Step Return

The unique aspect of Thawing Glaciers is its delayed triggered ability. After you resolve its activation, a trigger is created for the beginning of the next cleanup step. During that step, Thawing Glaciers returns to your hand. This prevents it from being used every single turn like a standard land but allows you to replay it from your hand on your next turn to repeat the search process.

Step-by-Step Resolution

First, ensure Thawing Glaciers is untapped at the start of your turn. Second, pay one mana and tap the land to activate its ability. Third, search your library for a basic land (such as a Forest or Island), put it onto the battlefield tapped, and shuffle. Finally, at the end of the current turn during the cleanup step, Thawing Glaciers leaves the battlefield and returns to your hand.

Strategic Timing

Since the return trigger happens during the cleanup step, you typically want to activate Thawing Glaciers on your opponent's end step. This ensures the land stays on the battlefield throughout your turn (perhaps as a target for other effects) before returning to your hand right before you start your next turn, ready to be played again.

Interaction examples

Fixing Your Colors

If you have Command Tower and Thawing Glaciers on the field, you can use the mana from Command Tower to pay the activation cost of Thawing Glaciers. This allows you to find a basic land that matches your commander's identity, ensuring you have the specific colors needed for your spells even if your hand is full of colorless lands.

The Search Choice

When you activate Thawing Glaciers, you are searching for a card with specific characteristics (a basic land). Even if you have basic lands in your library, you are not legally required to find one. If for some strategic reason you simply want to shuffle your library or trigger an 'activate an ability' effect without increasing your land count, you can choose to find nothing. You would still shuffle and Thawing Glaciers would still return to your hand at the next cleanup step.

How it works : Thawing Glaciers

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    The land put onto the battlefield does not count toward your one per turn limit because it was put onto the battlefield by an effect.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    Because the “search” requires you to find a card with certain characteristics, you don’t have to find the card if you don’t want to.

    No other card is named in this ruling.
