Steelswarm Operator turns every artifact you control into a free mana source by tapping them for colorless, and with Encroaching Mycosynth on the battlefield, that includes your entire creature base. Mm'menon, the Right Hand decks are the primary home, but any shell that goes wide with artifacts and wants to convert board presence into mana will find real use here.

Mm'menon, the Right Hand
Mm'menon, the Right Hand builds around artifacts and their interactions, and Steelswarm Operator slots directly into that engine — tapping your artifact permanents for mana accelerates the kind of explosive, mana-hungry turns Mm'menon rewards.

Steelswarm Operator is a Commander card through and through — the effect scales with the number of artifacts you control, which Commander's 100-card singleton format and longer game length are built to reward. In competitive non-rotating formats like Modern and Legacy, a three-mana artifact that taps others for colorless rarely clears the bar when faster mana sources exist and games end before the engine matters. Pioneer and Standard give it more room to breathe in artifact-heavy brews, but it still needs dedicated support to do real work. Commander is where it belongs.

Current price
$0.11 bulk tier
At $0.11, Steelswarm Operator is outright bulk — you're picking it up for essentially nothing. It won't hold or gain value, but that's irrelevant: if it fits your deck, the cost is a non-factor.
