Mirran Spy is a two-mana 1/3 that untaps an artifact creature whenever you cast a spell — on its own, that's unimpressive, but pair it with Emry, Lurker of the Loch and it becomes a free loop engine. Emry turns that untap trigger into infinite casts from the graveyard, which is why Mirran Spy shows up in 76% of Emry decks.

Commanders with the highest synergy

Emry, Lurker of the Loch
Mirran Spy is a core piece in Emry, Lurker of the Loch decks — Emry casts artifacts from the graveyard, Mirran Spy untaps her, and with a zero-mana artifact in the bin the loop generates infinite casts and whatever payoff you've wired in.

Lady Octopus, Inspired Inventor
Lady Octopus, Inspired Inventor triggers on artifact casts and benefits from repeated activations, making Mirran Spy's untap effect a reliable engine for chaining triggers and generating value across a long game.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | legal |
| oathbreaker | legal |
Mirran Spy is legal in Commander, Legacy, Modern, Pauper, Vintage, and Oathbreaker, but Commander is where it actually matters. In Pauper it's theoretically playable but too slow and narrow to compete. Legacy and Vintage have faster, more reliable combo infrastructure — Mirran Spy doesn't clear the bar there. Commander is its natural home: the singleton format rewards cheap, repeatable engines, and Mirran Spy fills that role cleanly in any artifact-based blue deck that can produce a loop condition.

Current price
$0.22 bulk tier
At $0.22, Mirran Spy is deep bulk — easy to trade for or pick out of a dollar bin. Given its combo-piece role in a popular commander archetype, that price is unlikely to spike significantly, but it's stable enough that there's no urgency in acquiring copies.
