Carte Magic Grand Architect

Grand Architect 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

Other blue creatures you control get +1/+1. {U}: Target artifact creature becomes blue until end of turn. Tap an untapped blue creature you control: Add {C}{C}. Spend this mana only to cast artifact spells or activate abilities of artifacts.

How it works : Grand Architect

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    Because damage remains marked on a creature until the damage is removed as the turn ends, nonlethal damage dealt to a blue creature you control may become lethal if Grand Architect leaves the battlefield during that turn.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    Grand Architect's second ability causes the affected artifact creature to lose any other colors it has, but it doesn't cause it to stop being an artifact.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    You can tap any untapped blue creature you control, including one you haven't controlled continuously since the beginning of your most recent turn, to pay the cost of Grand Architect's mana ability. This includes Grand Architect itself.

    No other card is named in this ruling.
