Carte Magic April O'Neil, Human Element

April O'Neil, Human Element 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

Whenever a player casts an artifact, instant, or sorcery spell, you create a Mutagen token. (It's an artifact with "{1}, {T}, Sacrifice this token: Put a +1/+1 counter on target creature. Activate only as a sorcery.")

How it works : April O'Neil, Human Element

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    April's ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered or otherwise leaves the stack.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    Mutagen tokens are a kind of predefined token. Each one is a colorless artifact with the artifact subtype Mutagen and the ability "{1}, {T}, Sacrifice this token: Put a +1/+1 counter on target creature. Activate only as a sorcery."

  3. #3· Wizards of the Coast

    Some spells and abilities that create Mutagen tokens require targets. If each target chosen is an illegal target as that spell or ability tries to resolve, it won't resolve. The Mutagen token won't be created.
