Is Rain of Filth good in Commander?

Rain of Filth in Commander — Combos, Decks & Price

Rain of Filth turns every land you control into a one-shot mana source — on the turn you need it, that's routinely six to ten mana for one black mana and a sorcery-speed slot. Decks like Rograkh, Son of Rohgahh // Silas Renn, Seeker Adept run it as a ritual that scales with board state rather than a fixed return, making it one of the most explosive burst-mana spells available in black.

Commanders with the highest synergy

01

Rograkh, Son of Rohgahh // Silas Renn, Seeker Adept

46.0% of decks · synergy 0.44

Rograkh, Son of Rohgahh // Silas Renn, Seeker Adept is a storm-adjacent combo deck that needs to chain spells in a single turn, and Rain of Filth plugs directly into that engine by converting an entire developed land base into mana on the critical turn.

02

The Gitrog Monster

33.3% of decks · synergy 0.32

The Gitrog Monster wants to sacrifice lands as a resource rather than treat them as sacred, so Rain of Filth is both a mana ritual and a way to feed the Frog's draw trigger by dumping lands into the graveyard en masse.

03

Gwenom, Remorseless

20.1% of decks · synergy 0.18

Gwenom, Remorseless builds toward a single explosive turn where every extra mana matters, and Rain of Filth provides the kind of sudden mana spike that lets the deck outpace the table when it goes off.

04

K'rrik, Son of Yawgmoth

18.3% of decks · synergy 0.16

K'rrik, Son of Yawgmoth already converts life into mana, and Rain of Filth stacks on top of that to generate a second wave of resources — together they can produce enough mana in one turn to empty a hand of expensive black spells.

05

Varragoth, Bloodsky Sire

16.9% of decks · synergy 0.14

Varragoth, Bloodsky Sire tutors at the cost of attacking, which means the payoff spell often needs to be cast the very next turn; Rain of Filth ensures the mana is there to immediately cast whatever Varragoth found.

Format Analysis

Where it lives, where it can’t

Format	Verdict
commander	legal
legacy	legal
modern	not legal
pioneer	not legal
standard	not legal
vintage	legal
pauper	not legal
oathbreaker	legal

Commander is where Rain of Filth does its best work — the format's larger land counts mean this ritual regularly produces five or more mana for one black, making it competitive with fast mana pieces that cost multiples of its price. In Legacy and Vintage, the comparison set is brutal: Dark Ritual and similar effects are faster, cheaper, and more consistent, so Rain of Filth sees essentially no competitive play in those formats. Oathbreaker runs it for the same reasons Commander does, particularly in black combo signatures where a land-based burst is sometimes the only line available. Anywhere it's legal, the card earns its slot only in decks that plan to sacrifice lands anyway or need a single massive mana spike — in a slower value-oriented build it's a dead card late.

Budget Alternatives

Cheaper options that do most of the same work

Cabal Ritual is the closest budget substitute at under a dollar, producing up to five black mana when threshold is active — it caps out lower than Rain of Filth on a developed board but costs nothing and asks nothing of your land count. Dark Ritual is even cheaper and more consistent but delivers a flat three mana, which means in the mid-to-late game scenarios where Rain of Filth shines brightest, Ritual falls significantly short.

Price Context

Current price

$28.24 premium tier

At $28.24, Rain of Filth sits in premium territory for a single-use instant with no reprint history to speak of, and that price reflects genuine demand from competitive Commander rather than hype. It holds value as long as black storm and land-sacrifice commanders remain popular, but it's a hard sell for anyone not explicitly building around the effect.
