Festering March is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Complete guide
Festering March is a relentless black sorcery that acts as a recurring plague for your opponents. By utilizing the Suspend keyword, it creates a cyclical effect that weakens the enemy's forces every few turns, ensuring their creatures struggle to survive.
A Recurring Blight
When Festering March resolves, it applies a -1/-1 penalty to all creatures your opponents control until the end of the turn. Instead of going to the graveyard, the card then exiles itself with three time counters. This sets it up to be cast again automatically via its Suspend ability, creating a loop where the spell haunts the battlefield every three turns.
Understanding the Suspend Loop
You can initiate Festering March by either casting it for its full cost of {3}{B}{B} or by paying its Suspend cost of {2}{B} during a main phase when the stack is empty. Once suspended, a time counter is removed at the beginning of each of your upkeeps. When the final counter is removed, a trigger goes on the stack that allows you to cast the spell without paying its mana cost. Because it exiles itself again as part of its resolution, this process repeats indefinitely unless the spell is countered or the triggered ability to cast it is declined.
Strategic Timing and Common Pitfalls
A common mistake is forgetting that Suspend timing follows normal casting rules for the initial exile: you can only suspend Festering March when you could normally cast a sorcery. However, when the last counter is removed, you cast it immediately during your upkeep, ignoring normal timing restrictions. If you choose not to cast the spell when the last counter is removed, or if the 'cast' trigger is countered, the card stays in exile forever and is no longer considered 'suspended' because it has no time counters.
Why Run Festering March?
This card is excellent for controlling board states filled with small creatures or tokens. Because the -1/-1 effect does not target, it bypasses Hexproof and Shroud. It serves as a persistent psychological pressure, forcing opponents to commit more resources to the board while knowing a sweep is coming in a predictable number of turns.
Interaction examples
DamnationIf your opponent has a large creature that survives Festering March's -1/-1 effect, you can still cast Damnation during your post-combat main phase. Festering March will have already finished resolving and moved itself to exile with time counters, ensuring it is safe from being destroyed and ready to return later.
Living DeathFestering March is particularly potent when paired with Living Death. As Festering March resolves and weakens your opponent's board, some creatures might die from having 0 toughness. When you later cast Living Death, those creatures are in the graveyard and can be swapped back, but since Festering March is in exile (suspended), it is not affected by Living Death's graveyard-swapping effect and continues its countdown.
On turn three, you pay {2}{B} to suspend Festering March. It enters exile with three time counters. On your next three upkeeps, you remove one counter. When the last is removed, you cast it for free. The creatures your opponents control get -1/-1, and Festering March returns to exile with three new counters to start the process again.

How it works : Festering March
Original English text — Wizards of the Coast / Scryfall
- #1· Wizards of the Coast
When the last time counter is removed, the second triggered ability of suspend (the one that lets you cast the card) triggers. It doesn't matter why the last time counter was removed or what effect removed it.
No other card is named in this ruling.
- #2· Wizards of the Coast
If the second triggered ability is countered, the card can't be cast. It remains exiled with no time counters on it, and it's no longer suspended.
No other card is named in this ruling.
- #3· Wizards of the Coast
Suspend is a keyword that represents three abilities. The first is a static ability that allows you to exile the card from your hand with the specified number of time counters (the number before the dash) on it by paying its suspend cost (listed after the dash). The second is a triggered ability that removes a time counter from the suspended card at the beginning of each of your upkeeps. The third is a triggered ability that gives you the option to cast the card when the last time counter is removed.
No other card is named in this ruling.
- #4· Wizards of the Coast
You can exile a card in your hand using suspend any time you could cast that card. Consider its card type, any effects that modify when you could cast it (such as flash) and any other effects that stop you from casting it (such as from Meddling Mage's ability) to determine if and when you can do this. Whether you could actually complete all steps in casting the card is irrelevant. For example, you can exile a card with suspend that has no mana cost or that requires a target even if no legal targets are available at that time.

- #5· Wizards of the Coast
Cards exiled with suspend are exiled face up.
No other card is named in this ruling.
- #6· Wizards of the Coast
Exiling a card with suspend isn't casting that card. This action doesn't use the stack and can't be responded to.
No other card is named in this ruling.
- #7· Wizards of the Coast
If the spell requires any targets, those targets are chosen when the spell is finally cast, not when it's exiled.
No other card is named in this ruling.
- #8· Wizards of the Coast
If an effect refers to a "suspended card," that means a card that (1) has suspend, (2) is in exile, and (3) has one or more time counters on it.
No other card is named in this ruling.
- #9· Wizards of the Coast
If the first triggered ability of suspend (the one that removes time counters) is countered, no time counter is removed. The ability will trigger again at the beginning of the card's owner's next upkeep.
No other card is named in this ruling.
- #10· Wizards of the Coast
Due to a recent rules change to suspend, you are no longer required to cast the suspended card as the second triggered ability of suspend resolves. Instead, as the second triggered ability resolves, you may cast the card. Timing permissions based on the card's type are ignored. If you don't cast the card, it remains exiled with no time counters on it, and it's no longer suspended.
No other card is named in this ruling.
- #11· Wizards of the Coast
If you cast a card "without paying its mana cost," such as with suspend, you can't choose to cast it for any alternative costs. You can, however, pay additional costs. If the card has any mandatory additional costs, you must pay those if you want to cast the card.
No other card is named in this ruling.
- #12· Wizards of the Coast
If the card has
in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.No other card is named in this ruling.
- #13· Wizards of the Coast
The mana value of a spell cast without paying its mana cost is determined by its mana cost, even though that cost wasn't paid.
