Is Conduit of Ruin good in Commander?

Conduit of Ruin in Commander — Combos, Decks & Price

Conduit of Ruin locks in your next Eldrazi draw and cuts its cost by two — that's a tutor stapled to a cost reducer on a six-mana body. The only real cost is the mana, and in any deck built around colorless fatties, six mana is not a problem.

Commanders with the highest synergy

01

Ulalek, Fused Atrocity

55.4% of decks · synergy 0.52

Conduit of Ruin is in over half of all Ulalek, Fused Atrocity decks because it does exactly what that deck needs: it finds the next Eldrazi and makes it cheaper, setting up the cascade of triggered copies that Ulalek depends on.

02

Herigast, Erupting Nullkite

40.8% of decks · synergy 0.40

Herigast, Erupting Nullkite wants a steady pipeline of large Eldrazi to emerge and attack, and Conduit of Ruin guarantees the next one is waiting on top of the library at a discount.

03

Belbe, Corrupted Observer

39.5% of decks · synergy 0.39

Belbe, Corrupted Observer generates bursts of colorless mana by dealing damage, and Conduit of Ruin converts that sudden surplus directly into a discounted Eldrazi bomb the turn you need it.

04

Kozilek, the Great Distortion

70.9% of decks · synergy 0.34

Conduit of Ruin appears in over 70% of Kozilek, the Great Distortion lists because fetching Kozilek off the top and shaving two mana off the cast is often the difference between deploying it on curve and watching it sit in hand.

Zhulodok, Void Gorger

Zhulodok, Void Gorger turns every colorless spell over seven mana into a cascading value engine, and Conduit of Ruin sets the table by tutoring the right Eldrazi to the top while making it cheaper to cast.

Commander is where Conduit of Ruin belongs — the 100-card singleton format rewards the guaranteed-top-card tutor more than any other, since you only run one copy of each payoff and cannot afford to brick. Outside of Commander, the card sees essentially no competitive play: six mana is far too slow for Modern or Pioneer, where the Eldrazi synergy shells that do exist rely on cheaper enablers and faster mana. Legacy and Vintage are legal, but the same logic applies even harder — Conduit of Ruin is not doing anything those formats can't accomplish faster. Stick to Commander, and specifically to decks running eight or more Eldrazi that cost seven or more, where the tutor effect translates directly into a repeatable game-winning sequence.
