Dust of Moments
A purpose-built lever for the time-counter economy, and a rare instant that treats suspend as a resource to be sped up or stalled rather than merely cast. The two modes pull in opposite directions on the same axis: strip two counters to hurry everything along (your own suspended spells resolve sooner, vanishing creatures hit their sacrifice trigger faster, any permanent counting down to a payoff arrives early), or pile two counters on to drag the clock and push those same payoffs out of reach. Notice the asymmetry the design builds into the second half: the acceleration mode removes counters from every permanent and every suspended card, but the deceleration mode adds them only to suspended cards and permanents that already carry a time counter, so it cannot freeze a board that was never on a timer to begin with. That restriction is what keeps a sweeping clock-manipulator from being broken: it does little against a deck with no counters in play, and everything in a shell built around suspend, vanishing, and the handful of permanents that tick toward a reward. At instant speed it can fire in response to a suspended spell's final tick or an opponent's planned timing, collapsing or extending a window they assumed was fixed. It is less a spell than a clock wrench, and the cleverness is in choosing which way to turn it.
