Schlüssel zum Tresorgewölbe

Immer wenn die ausgerüstete Kreatur einem Spieler Kampfschaden zufügt, schaue dir entsprechend viele Karten oben von deiner Bibliothek an. Du kannst davon eine Nichtland-Karte ins Exil schicken. Lege den Rest in zufälliger Reihenfolge unter deine Bibliothek. Du kannst die ins Exil geschickte Karte wirken, ohne ihre Manakosten zu bezahlen.

La clé du coffre-fort

À chaque fois que la créature équipée inflige des blessures de combat à un joueur, regardez autant de cartes du dessus de votre bibliothèque. Vous pouvez exiler une carte non-terrain parmi elles. Mettez le reste au-dessous de votre bibliothèque dans un ordre aléatoire. Vous pouvez lancer la carte exilée sans payer son coût de mana.

The Key to the Vault

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.

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.

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.

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.
