Backslide

A targeted answer to one of the trickier rules wrinkles in the morph kit: the card can only point at a creature with a morph ability, but within that restriction it does work nothing else does at this price. Turning a face-up morph creature face down reverts it to its base 2/2 with no abilities, stripping whatever it had unmorphed into until someone pays to turn it face up again. Aimed at an opponent's revealed morph, that is a tempo-positive reset that buys back a turn of investment and demotes a threat to a vanilla body. Aimed at your own, it sets up a second go at the unmorph trigger, since a creature turned face up fires its "as this is turned face up" ability each time it flips. The cycling clause buys insurance against the dead-card scenario: in any game where no morph creature ever surfaces, this shrinks to a one-mana cantrip rather than a stranded answer. That dual identity (a narrow blowout against face-down decks, a replacement draw against everyone else) is the design discipline that lets a hyper-specific interaction spell exist without punishing the games where it never matters. It comes from an effort to build morph into a full strategic axis, where the mechanic needed cards that interacted with face-down status from both directions; Backslide is the cheapest spell policing the morph mirror, and it pays its own way when the mirror never comes.
