- 712.1 A meld card has a Magic card face on one side and half of an oversized Magic card face on the other. It doesn’t have a Magic card back.
- 712.1a There are three specific meld pairs. Each meld pair consists of two specific cards whose back faces combine to form one oversized Magic card face: Midnight Scavengers and Graf Rats meld to form Chittering Host; Hanweir Garrison and Hanweir Battlements meld to form Hanweir, the Writhing Township; and Bruna, the Fading Light and Gisela, the Broken Blade meld to form Brisela, Voice of Nightmares.
- 712.1b A meld card isn’t a double-faced card. It can’t transform or enter the battlefield transformed. (See rule 711, “Double-Faced Cards.”)
- 712.3a While a meld 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.
- 712.3b While the two cards of a meld pair are on the battlefield as a melded permanent, the object represented by those cards has only the characteristics of the combined back face, and its converted mana cost is the sum of the converted mana costs of its front faces. If a permanent is copying a melded permanent, the converted mana cost of the copy is 0. See rule 202.3c.
- 712.3c Anything that needs information about a meld card or a melded permanent sees only the information given by the face that is currently up.
Example: A Clone enters the battlefield as a copy of Chittering Host (the combined back face of a meld pair). It has the characteristics of Chittering Host, even though the object it becomes is represented by only a single card, and its converted mana cost is 0.
- 712.4 If a melded permanent leaves the battlefield, one permanent leaves the battlefield and two cards are put into the appropriate zone.
Example: Chittering Host, a melded permanent, dies. An ability that triggers “whenever a creature dies” triggers once. An ability that triggers “whenever a card is put into a graveyard from anywhere” triggers twice.
- 712.4a If a melded permanent is put into its owner’s graveyard or library, that player may arrange the two cards in any order. If it’s put into its owner’s library, that player doesn’t reveal the order.
- 712.4b If a player exiles a melded permanent, that player determines the relative timestamp order of the two cards at that time. This is an exception to the procedure described in rule 613.6j.
Example: Duplicant is a card with the abilities “When Duplicant enters the battlefield, you may exile target nontoken creature” and “As long as a card exiled with Duplicant is a creature card, Duplicant has the power, toughness, and creature types of the last creature card exiled with Duplicant. It’s still a Shapeshifter.” As Duplicant’s first ability exiles Chittering Host, a melded permanent, Duplicant’s controller chooses whether the last creature card exiled is Midnight Scavengers or Graf Rats.
- 712.4c If an effect can find the new object that a melded permanent becomes as it leaves the battlefield, it finds both cards. (See rule 400.7.) If that effect causes actions to be taken upon those cards, the same actions are taken upon each of them.
Example: Otherworldly Journey is an instant that reads “Exile target creature. At the beginning of the next end step, return that card to the battlefield under its owner’s control with a +1/+1 counter on it.” A player casts Otherworldly Journey targeting Chittering Host, a melded permanent. Chittering Host is exiled. At the beginning of the next end step, Midnight Scavengers and Graf Rats are both returned to the battlefield, each with a +1/+1 counter on it.
Example: False Demise is an Aura with the ability “When enchanted creature dies, return that card to the battlefield under your control.” A Chittering Host enchanted by False Demise dies. The triggered ability returns both Midnight Scavengers and Graf Rats to the battlefield.
Example: False Demise is an Aura with the ability “When enchanted creature dies, return that card to the battlefield under your control.” A Chittering Host enchanted by False Demise dies. The triggered ability returns both Midnight Scavengers and Graf Rats to the battlefield.
Example: Mimic Vat is an artifact that reads, in part, “Whenever a nontoken creature dies, you may exile that card.” A Chittering Host dies. As Mimic Vat’s triggered ability resolves, its controller makes a single choice and both cards that represented Chittering Host are either exiled or not.
- 712.4d If multiple replacement effects could be applied to the event of a melded permanent leaving the battlefield or being put into the new zone, applying one of those replacement effects to one of the two cards affects both cards. If the melded permanent is a commander, it may be exempt from this rule; see rule 903.9a.
Example: Leyline of the Void is an enchantment that reads, in part, “If a card would be put into an opponent’s graveyard from anywhere, exile it instead.” Wheel of Sun and Moon is an Aura with enchant player and the ability “If a card would be put into enchanted player’s graveyard from anywhere, instead that card is revealed and put on the bottom of its owner’s library.” If the controller of Chittering Host is affected by both cards’ effects, that player chooses one effect to apply to the event and Midnight Scavengers and Graf Rats are both moved to the appropriate zone.
- 712.4e If an effect needs to know the number of objects that changed zones, a melded permanent among those objects counts as one object that moved. If the effect needs to know the number of cards that changed zones, that melded permanent counts as two cards that moved.
