Carte Magic Determined Iteration

Determined Iteration 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

At the beginning of combat on your turn, populate. The token created this way gains haste. Sacrifice it at the beginning of the next end step. (To populate, create a token that's a copy of a creature token you control.)

How it works : Determined Iteration

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    If you choose to copy a creature token that's a copy of another creature, the new creature token will copy the characteristics of whatever the original token is copying.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    Populate doesn't target the creature token you're copying. You choose that creature token as you're taking the populate action. You can choose any creature token you control. If a spell or ability causes you to create a creature token and then instructs you to populate, you may choose to copy the token you just created, or you may choose to copy another creature token you control.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    Any enters-the-battlefield abilities of the copied token will trigger when the new token enters the battlefield. Any "as [this creature] enters the battlefield" or "[this creature] enters the battlefield with" abilities of the copied token will also work.

    No other card is named in this ruling.

  4. #4· Wizards of the Coast

    The new token doesn't copy whether the original token is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any noncopy effects that have changed its power, toughness, color, and so on.

    No other card is named in this ruling.

  5. #5· Wizards of the Coast

    If you control no creature tokens when you populate, nothing will happen.

    No other card is named in this ruling.

  6. #6· Wizards of the Coast

    The new creature token copies the characteristics of the original token as stated by the effect that created the original token.

    No other card is named in this ruling.
