Ojutai's Breath

Rebound is the mechanic that lifts this out of the throwaway tempo trick it would otherwise be. A bare tap-and-hold-down effect at instant speed wins a combat or buys a turn and then sits in the graveyard; here, the first cast pays for one resolution now, exiles the card, and hands you a second, free resolution one turn later. That deferred cast is the design's whole purpose. It is not a copy: the exiled card itself waits, and when you cast it again it is a fresh spell that picks its own target. That stretches one card's disruption across a window the opponent cannot collapse. You can hold down the same attacker again if it is still the threat that matters, or point the second cast at whatever stood up in the meantime: a new blocker, a freshly resolved bomb, a different creature angling to swing back. Note that two casts on the same creature do not stack into a two-turn lock if you fire the first on the opponent's turn; both "doesn't untap" clauses reference the same next untap step and overlap harmlessly. The repetition lives across turns, not within one. It is the patient, recurring cousin of a hard answer, trading permanence for two separate moments of denial scheduled on your clock rather than theirs.
