Carte Magic Rootha, Mastering the Moment

Rootha, Mastering the Moment 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, if you've cast an instant or sorcery spell this turn, create an X/X blue and red Elemental creature token with flying and haste, where X is the greatest mana value among instant and sorcery spells you've cast this turn.

How it works : Rootha, Mastering the Moment

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    For spells you cast with {X} in their mana costs, use the value chosen for X to determine the spell's mana value.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    Rootha's ability will check as your beginning of combat step starts to see if you've cast an instant or sorcery spell this turn. If you haven't, the ability won't trigger at all. It's not possible to cast an instant or sorcery spell during your beginning of combat step in time to have the ability trigger.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    A spell's mana value is determined only by its mana cost. Ignore any alternative costs, additional costs, cost increases, or cost reductions.

    No other card is named in this ruling.
