Primordial Mist

13/07/18

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.

13/07/18

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

13/07/18

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.

13/07/18

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.

13/07/18

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 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.

13/07/18

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.

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).

13/07/18

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.
