Urnebel

Zu Beginn deines Endsegments kannst du die oberste Karte deiner Bibliothek manifestieren. (Bringe sie als eine 2/2 Kreatur verdeckt ins Spiel. Decke sie zu einem beliebigen Zeitpunkt für ihre Manakosten auf, falls es eine Kreaturenkarte ist.)
Schicke eine verdeckte bleibende Karte, die du kontrollierst, aufgedeckt ins Exil: Du kannst die Karte in diesem Zug spielen. (Du bezahlst immer noch ihre Kosten. Zeitpunkts-Einschränkungen gelten weiterhin.)

Niebla primordial

Al comienzo de tu paso final, puedes manifestar la primera carta de tu biblioteca. (Ponla en el campo de batalla boca abajo como una criatura 2/2. Ponla boca arriba en cualquier momento por su coste de maná si es una carta de criatura.)
Exiliar boca arriba un permanente boca abajo que controlas: Puedes jugar esa carta este turno. (Sigues pagando sus costes. Las reglas sobre cuándo jugarla se siguen aplicando.)

Brume primordiale

Au début de votre étape de fin, vous pouvez manifester la carte du dessus de votre bibliothèque. (Mettez-la sur le champ de bataille face cachée comme une créature 2/2. Retournez-la face visible à tout moment pour son coût de mana si c'est une carte de créature.)
Exilez, face visible, un permanent face cachée que vous contrôlez : Vous pouvez jouer cette carte ce tour-ci. (Vous payez toujours ses coûts. Les restrictions de temps s'appliquent quand même.)

Nebbia Primordiale

All'inizio della tua sottofase finale, puoi manifestare la prima carta del tuo grimorio. (Mettila sul campo di battaglia a faccia in giù come una creatura 2/2. Se è una carta creatura, girala a faccia in su in qualsiasi momento pagando il suo costo di mana.)
Esilia a faccia in su un permanente a faccia in giù che controlli: Puoi giocare quella carta in questo turno. (Paghi comunque i suoi costi. Le regole sulla tempistica si applicano comunque.)

始源の霧

あなたの終了ステップの開始時に、あなたはあなたのライブラリーの一番上のカードを予示してもよい。（それを裏向きの状態で２/２クリーチャーとして戦場に出す。それがクリーチャー・カードであるなら、そのマナ・コストで、いつでも表向きにしてよい。）
あなたがコントロールしている裏向きのパーマネント１つを表向きに追放する：このターン、あなたはそのカードをプレイしてもよい。（そのコストは支払う必要がある。タイミングのルールも依然として適用される。）

Névoa Primordial

No início de sua etapa final, você pode manifestar o card do topo de seu grimório. (Coloque-o no campo de batalha com a face voltada para baixo como uma criatura 2/2. Volte sua face para cima a qualquer momento pagando seu custo de mana se for um card de criatura.)
Exile uma permanente com a face voltada para baixo que você controla: Você pode jogar aquele card neste turno. (Você ainda paga seus custos. As regras de tempo ainda se aplicam.)

Primordial Mist

At the beginning of your end step, you may manifest the top card of your library. (Put it onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it's a creature card.)
Exile a face-down permanent you control face up: You may play that card this turn. (You still pay its costs. Timing rules still apply.)

A permanent that turns face up or face down changes characteristics but is otherwise the same permanent. Spells and abilities that were targeting that permanent, as well as Auras and Equipment that were attached to the permanent, aren't affected.

Activating Primordial Mist's last ability doesn't trigger abilities that trigger "when [something] is turned face up."

Any time you have priority, you may turn a manifested creature face up by revealing that it's a creature card (ignoring any type-changing effects that might be applying to it) and paying its mana cost. This is a special action. It doesn't use the stack and can't be responded to.

At any time, you can look at a face-down permanent you control. You can't look at face-down permanents you don't control unless an effect instructs you to do so.

Because face-down creatures don't have a name, they can't have the same name as any other creature or share any creature types with any other creature, even another face-down creature.

Because the permanent is on the battlefield both before and after it's turned face up, turning a permanent face up doesn't cause any enters-the-battlefield abilities to trigger.

Casting an exiled card causes it to leave exile. You can't cast it multiple times.

If a face-down permanent you control leaves the battlefield, you must reveal it. You must also reveal all face-down spells and permanents you control if you leave the game or if the game ends.

If an effect tries to return a face-down creature to the battlefield after it leaves (such as Aminatou's second ability or Adarkar Valkyrie's delayed triggered ability), that effect returns the card face up. If it tries to put an instant or sorcery card onto the battlefield this way, that card remains in its current zone instead.

If you activate Primordial Mist's last ability but don't play the exiled card this turn, it remains exiled.

If you somehow control a face-down token, you may exile it to activate Primordial Mist's last ability, but you won't be able to cast that token.

Some previous Magic sets feature double-faced cards, which have a Magic card face on each side rather than a Magic card face on one side and a Magic card back on the other. If a double-faced card is manifested, it will be put onto the battlefield face down. While face down, it can't transform. If the front face of the card is a creature card, you can turn it face up by paying its mana cost. If you do, its front face will be up. Although a double-faced card can enter the battlefield face down, one already on the battlefield can't be turned face down.

The face-down characteristics of a permanent are copiable values. If another object becomes a copy of a face-down creature or if a token is created that's a copy of a face-down creature, that new object is a 2/2 colorless face-up creature with no abilities.

The face-down permanent is a 2/2 creature with no name, mana cost, creature types, or abilities. It's colorless and has a mana value of 0. Other effects that apply to the permanent can still grant or change any of these characteristics.

There are no cards in this set that would turn a face-down instant or sorcery card on the battlefield face up, but some older cards can try to do this. If something tries to turn a face-down instant or sorcery card on the battlefield face up, reveal that card to show all players it's an instant or sorcery card. The permanent remains on the battlefield face down. Abilities that trigger when a permanent turns face up won't trigger, because even though you revealed the card, it never turned face up.

Turning a permanent face up or face down doesn't change whether that permanent is tapped or untapped.

You may play a land exiled this way only if you have an available land play this turn.

You must ensure that your face-down spells and permanents can easily be differentiated from each other. You're not allowed to mix up the cards that represent them on the battlefield to confuse other players. The order they entered the battlefield should remain clear. Common methods for indicating this include using markers or dice, or simply placing them in order on the battlefield. You must also track how each became face down (manifested, cast face down using a morph ability, and so on).

You must follow the normal timing permissions and restrictions of each card you play.

You'll still pay all costs for a spell cast this way, including additional costs. You may also pay alternative costs such as evoke costs.
