Brotherhood Spy turns every Assassin you cast into a free loot — draw a card, discard a card — which keeps Assassin-tribal engines running without spending extra mana. At two mana for a 1/1, you're not playing it for the body; you're playing it because Etrata, Deadly Fugitive needs every card-selection tool available to find her hit targets consistently.
Best Commanders
Commanders with the highest synergy
Etrata, Deadly Fugitive
Etrata, Deadly Fugitive is the home — Brotherhood Spy's loot trigger fires on every Assassin cast, which means Etrata's token-generating kills translate directly into card filtering that digs toward more hits and keeps the combo clock ticking.
Ramses, Assassin Lord
Ramses, Assassin Lord turns Assassin density into a win condition, and Brotherhood Spy rewards that density with looting on every Assassin cast, smoothing out the draws needed to flood the board and close games before opponents stabilize.
Ezio Auditore da Firenze
Ezio Auditore da Firenze runs enough Assassins to trigger Brotherhood Spy regularly, and the looting helps cycle past dead draws to find the evasive threats Ezio needs to push damage through and accumulate his poison counters.
Ratonhnhaké꞉ton
Ratonhnhaké꞉ton cares about Assassins and combat, so Brotherhood Spy's incidental card selection on each Assassin cast keeps the hand full during the aggressive turns where Ratonhnhaké꞉ton wants to be attacking, not running out of gas.
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 | not legal |
| oathbreaker | legal |
Commander is where Brotherhood Spy does all of its real work — Assassin tribal is a niche but established archetype, and the looting payoff is worth a deck slot in any build that casts five or more Assassins a game. In Legacy and Vintage it's legal but irrelevant; no competitive shell wants a 1/1 loot-on-Assassin-cast effect when those formats don't support the tribe. Brotherhood Spy is a Commander-only pickup in practice.

Price Context
Current price
$0.20 bulk tier
At $0.20, Brotherhood Spy is pure bulk — pick up as many copies as you need without thinking about it. Bulk rares with narrow tribal applications rarely climb in price, so don't expect this to move.
