What it does

Whenever equipped creature deals combat damage to a player, look at that many cards from the top of your library. You may exile a nonland card from among them. Put the rest on the bottom of your library in a random order. You may cast the exiled card without paying its mana cost.

Rulings

3 official rulings, in the order Wizards published them.

  • 2024-04-12

    If you cast a spell “without paying its mana cost,” you can’t choose to cast it for any alternative costs. You can, however, pay additional costs, such as kicker costs. If the spell has any mandatory additional costs, those must be paid to cast the spell.

  • 2024-04-12

    You choose whether to cast the exiled card as The Key to the Vault’s triggered ability resolves. If you do, you do so as part of the resolution of that ability. You can’t wait to cast it later in the turn. Timing restrictions based on the card’s types are ignored.

  • 2024-04-12

    If the spell you cast has X in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.

Rulings are Wizards of the Coast's own, mirrored from Scryfall and refreshed nightly.

Every version of The Key to the Vault

5 printings, newest first. Prices are the market figures Scryfall publishes, refreshed nightly. A printing with no figure shows a dash rather than a zero, because Scryfall publishes none for some of them.

Prices from Scryfall, which tracks the TCGplayer and Cardmarket markets. They move daily and are a guide rather than a quote. Search TCGplayer for The Key to the Vault. It runs a name search across every version, which covers the printings TCGplayer publishes no direct link to.

Aggregated from Commander games tracked in TurnZero HQ. Every figure counts decks and games only. No individual deck list, player or playgroup is identified. Win rates are withheld below 5 completed games, where the sample is too small to mean anything.
