Unnatural Summons

To manifest a card, turn it face down. It becomes a 2/2 face-down creature card with no text, no name, no subtypes, and no mana cost. Put that card onto the battlefield face down. That permanent is a manifested permanent for as long as it remains face down. The effect defining its characteristics works while the card is face down and ends when it’s turned face up.

Any time you have priority, you may turn a manifested permanent you control face up. This is a special action that doesn’t use the stack (see rule 116.2b). To do this, show all players that the card representing that permanent is a creature card and what that card’s mana cost is, pay that cost, then turn the permanent face up. The effect defining its characteristics while it was face down ends, and it regains its normal characteristics. (If the card representing that permanent isn’t a creature card or it doesn’t have a mana cost, it can’t be turned face up this way.)

If a card with morph is manifested, its controller may turn that card face up using either the procedure described in rule 702.37e to turn a face-down permanent with morph face up or the procedure described above to turn a manifested permanent face up.

If a card with disguise is manifested, its controller may turn that card face up using either the procedure described in rule 702.168d to turn a face-down permanent with disguise face up or the procedure described above to turn a manifested permanent face up.

If an effect instructs a player to manifest multiple cards from their library, those cards are manifested one at a time.

If an effect instructs a player to manifest a card and a rule or effect prohibits the face-down object from entering the battlefield, that card isn’t manifested. Its characteristics remain unmodified and it remains in its previous zone. If it was face up, it remains face up.

If a manifested permanent that’s represented by an instant or sorcery card would turn face up, its controller reveals it and leaves it face down. Abilities that trigger whenever a permanent is turned face up won’t trigger.

See rule 708, “Face-Down Spells and Permanents,” for more information.

“Manifest dread” means “Look at the top two cards of your library. Manifest one of them, then put the cards you looked at that were not manifested this way into your graveyard.” See rule 701.34, “Manifest.”

An ability that triggers whenever a player manifests dread triggers after the process described in rule 701.60a is complete, even if some or all of those actions were impossible.

Rebound appears on some instants and sorceries. It represents a static ability that functions while the spell is on the stack and may create a delayed triggered ability. “Rebound” means “If this spell was cast from your hand, instead of putting it into your graveyard as it resolves, exile it and, at the beginning of your next upkeep, you may cast this card from exile without paying its mana cost.”

Casting a spell as an effect of its rebound ability follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Multiple instances of rebound on the same spell are redundant.
