Carte Magic Isshin, Two Heavens as One

Isshin, Two Heavens as One 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 a creature attacking causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time.

How it works : Isshin, Two Heavens as One

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    Isshin, Two Heavens as One's ability affects only triggered abilities with conditions that are directly related to attacking, such as “whenever [this creature] attacks” or “whenever you attack with one or more creatures.” It does not affect triggered abilities with other trigger conditions, such as “whenever [this creature] becomes tapped.”

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    Isshin's effect doesn't copy the triggered ability; it just causes the ability to trigger twice. Any choices made as you put the ability onto the stack, such as modes and targets, are made separately for each instance of the ability. Any choices made on resolution are also made individually.

    No other card is named in this ruling.
