Stitched Mangler

The disruption is a one-shot tap-and-freeze on an opposing creature, and the enters-tapped clause is the tax the design charges for it. Tapping a target creature and denying its next untap step keeps an opposing attacker or blocker off the board for a full cycle, long enough to swing through unopposed or push a slower clock past a wall that would otherwise stabilize. But the self-tap splits the value across two turns: the turn you cast it you buy the tap-down without gaining a blocker, and by the time the 2/3 can hold the line the lock has already expired. That staggering is what stops the double-tempo (freeze a body, add one of your own) from being free. The Zombie Horror line is the wrinkle that changes its ceiling. In a color usually short on bodies, a graveyard-relevant creature with a one-time disruption rider becomes something different in a recursion shell than it is as a single cast: every re-entry retriggers the tap-and-hold, so the rider that reads as one use turns into a repeatable lock on whatever the opponent most wants untapped. Cast once, it is a fair-rate tempo creature with a short leash; looped, the leash comes off.
