Carte Magic Oath of Teferi

Oath of Teferi 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 Oath of Teferi enters, exile another target permanent you control. Return it to the battlefield under its owner's control at the beginning of the next end step. You may activate the loyalty abilities of planeswalkers you control twice each turn rather than only once.

Complete guide

Oath of Teferi is a powerful legendary enchantment that doubles the utility of your planeswalkers and provides immediate value through a flicker effect. It is a cornerstone for any 'Superfriends' deck, ensuring your heroes can impact the board twice as often while resetting one of your key permanents.

Mastering Loyalty and Time

Oath of Teferi has two primary functions. First, it features an 'enters-the-battlefield' trigger that exiles another target permanent you control and returns it at the next end step. Second, it creates a static rule change for your planeswalkers: you may activate their loyalty abilities twice each turn. This applies to every planeswalker you control, allowing you to use the same ability twice or two different ones.

Resolving the Flicker Effect

When Oath of Teferi enters the battlefield, you choose a target permanent you control other than the Oath itself. That permanent is moved to the exile zone immediately. It remains there until the beginning of the next end step, at which point it returns to the battlefield under its owner's control. If the target was a token, it ceases to exist once it hits exile and will never return.

Limitations and Layering

It is important to note that controlling multiple copies of Oath of Teferi does not stack the loyalty benefit; you are still limited to a maximum of two activations per turn. Additionally, if the exiled permanent is an Aura, it returns without targeting, meaning you can attach it to permanents with hexproof, though it must still legally be able to enchant that object type.

Interaction examples

Resetting the Tithe

If you cast Oath of Teferi while Smothering Tithe is on the battlefield, you can target the Tithe with the exile trigger. The Tithe will leave the battlefield, then return at the end step. While this doesn't generate extra mana immediately, it can be used to 'save' your Smothering Tithe from an opponent's targeted removal spell cast in response to the Oath.

Drawing into the Future

With Kindred Discovery on the battlefield naming 'Humans', you cast Oath of Teferi and target a Human creature you control. The Human is exiled. At the next end step, the Human returns to the battlefield. This 'enters' event triggers Kindred Discovery, allowing you to draw a card. This interaction highlights how Oath of Teferi can re-trigger your powerful 'enters' effects.

How it works : Oath of Teferi

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    If a token is exiled this way, it ceases to exist and won’t return to the battlefield.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    The exiled card will return to the battlefield at the beginning of the next end step even if Oath of Teferi is no longer on the battlefield at that time.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    If the exiled card is an Aura, that card’s owner chooses what it will enchant as it returns to the battlefield. An Aura put onto the battlefield this way doesn’t target anything (so it could be attached to an opponent’s permanent with hexproof, for example), but the Aura’s enchant ability restricts what it can be attached to. If the Aura can’t legally be attached to anything, it remains exiled.

    No other card is named in this ruling.

  4. #4· Wizards of the Coast

    For Oath of Teferi’s second ability, you may activate the same ability of a planeswalker twice, or you may activate two different abilities of that planeswalker.

    No other card is named in this ruling.

  5. #5· Wizards of the Coast

    If you somehow control more than one Oath of Teferi, you won’t be able to activate abilities of planeswalkers you control more than twice in one turn.

    No other card is named in this ruling.
