Festering March

A board-wide -1/-1 that re-exiles itself with three fresh time counters every time it resolves: that self-recurring loop, not the sweep, is the engine this design is built around. Cast it through suspend for and you commit to a clock that fires on your upkeep three turns out, then resets and fires again, a sorcery that keeps casting itself so long as nothing interrupts the cycle. The cost is information: your opponent watches the counters tick down and knows exactly when the wave of -1/-1 lands, so they can hold back one-toughness bodies, develop creatures that survive a single shrink, or simply wait out the window. The trade is broadcast tempo for a repeatable effect, and against a go-wide deck the recurrence is what turns the screw, because every token committed between resolutions is a token marked for a death everyone can see scheduled in advance. The timing matters too: suspend casts the spell at the beginning of your upkeep, which falls after you untap but before your draw step, so a board that looked stable at the end of the opponent's turn can shrink before they take another action. What this asks of the pilot is forecasting rather than reaction, reading the table several turns deep, which is precisely the axis suspend was meant to explore when bolted onto an effect that would otherwise be a one-and-done sorcery pointed at a crowd.
