- 711.1 A double-faced card has a Magic card face on each side rather than a Magic card face on one side and a Magic card back on the other. Each face may have abilities that allow the card to “transform,” or turn over to its other face. Tokens and cards with a Magic card back can’t transform. (See rule 701.27, “Transform.”)
- 711.1a A double-faced card’s front face is marked by a front-face symbol in its upper left corner. On Magic Origins and Core Set 2019 double-faced cards, the front-face symbol is a modified Planeswalker icon. On cards in the Innistrad block and Shadows over Innistrad set, as well as on Ulrich of the Krallenhorde in the Eldritch Moon set, the front-face symbol is a sun. On other Eldritch Moon double-faced cards, the front-face symbol is a full moon. On Ixalan cards, the front-face symbol is a compass rose.
- 711.1b A double-faced card’s back face is marked by a back-face symbol in its upper left corner. On Magic Origins and Core Set 2019 double-faced cards, the back-face symbol is a full Planeswalker icon. On cards in the Innistrad block and Shadows over Innistrad set, as well as on Ulrich, Uncontested Alpha in the Eldritch Moon set, the back-face symbol is a crescent moon. On other Eldritch Moon double-faced cards, the back-face symbol is a stylized image of Emrakul. On Ixalan cards, the back-face symbol is a land icon.
- 711.1c If the back face of a double-faced card is a creature, the front face of that card will have the back face’s power and toughness printed in gray above the power and toughness box. This is reminder text and has no effect on game play.
- 711.1d Meld cards have a Magic card face on one side and half of an oversized Magic card face on the other. These aren’t double-faced cards and are subject to their own set of rules. See rule 712, “Meld Cards.”
- 711.3a A checklist card has a normal Magic card back. The face of a checklist card is divided into sections. Each section lists the name and mana cost of each double-faced card it could represent and includes a fill-in circle. Before a checklist card can be used, exactly one of the fill-in circles must be marked to denote which double-faced card the checklist card represents.
- 711.3b If a checklist card is used in a deck, the double-faced card it represents is set aside prior to the beginning of the game (see rule 103.1a) and must remain available throughout the game. A checklist card can’t be included in a deck unless it is representing a double-faced card.
- 711.3c For all game purposes, the checklist card is considered to be the double-faced card it’s representing.
- 711.3d If the checklist card is face up in a public zone, it should be set aside and the double-faced card used instead.
- 711.4a While a double-faced card is outside the game, in a zone other than the battlefield, or on the battlefield with its front face up, it has only the characteristics of its front face.
- 711.4b While a double-faced permanent’s back face is up, it has only the characteristics of its back face. However, its converted mana cost is calculated using the mana cost of its front face. If a permanent is copying the back face of a double-faced card (even if the card representing that copy is itself a double-faced card), the converted mana cost of that permanent is 0.
Example: A Clone enters the battlefield as a copy of Wildblood Pack (the back face of a double-faced card). The Clone will be a copy of the Wildblood Pack. Because the Clone is itself not a double-faced card, it can’t transform.
Example: A player casts Cytoshape, causing a Kruin Outlaw (the front face of a double-faced card) to become a copy of Elite Vanguard (a 2/1 Human Soldier creature) until end of turn. The player then casts Moonmist, which reads, in part, “Transform all Humans.” Because the copy of Elite Vanguard is a double-faced card, it will transform. The resulting permanent will have its back face up, but it will still be a copy of Elite Vanguard that turn.
- 711.6 If a spell or ability instructs a player to transform a permanent, and the face that permanent would transform into is represented by an instant or sorcery card face, nothing happens.
- 711.7 If a double-faced card is cast as a spell, it’s put on the stack with its front face up. See rule 601, “Casting Spells.”
- 711.8 A double-faced card enters the battlefield with its front face up by default. If a spell or ability puts it onto the battlefield “transformed,” it enters the battlefield with its back face up.
- 711.8a If a player is instructed to put a card that isn’t a double-faced card onto the battlefield transformed, that card stays in its current zone.
- 711.9a While face down, a double-faced permanent can’t transform. If it is turned face up, it will have its front face up.
- 711.13 If an effect instructs a player to choose a card name, the player may name either face of a double-faced card but not both.
