Roshan, Hidden Magister card art
Roshan, Hidden Magister turns every Assassin that connects into a tutor-plus-deploy engine, which is an absurd amount of card advantage stapled to combat damage triggers. The catch is that he only works if you're already built around Assassins — in any other shell he's a do-nothing 4/4 for five mana, and Etrata, Deadly Fugitive decks are the only place he consistently earns that slot.

Commanders with the highest synergy

01
Etrata, Deadly Fugitive

Etrata, Deadly Fugitive

88.3% of decks · synergy 0.87

Etrata, Deadly Fugitive is the natural home for Roshan, Hidden Magister — Etrata's hit-triggers and clone-based attack plan fill the board with Assassins, and Roshan converts each successful connection into a free creature deployed directly from the deck.

02
Altaïr Ibn-La'Ahad

Altaïr Ibn-La'Ahad

59.2% of decks · synergy 0.58

Altaïr Ibn-La'Ahad builds around leveling up Assassins through kills, and Roshan, Hidden Magister feeds that engine by pulling more Assassins out of the library whenever one connects, keeping the chain going without spending cards from hand.

03
Ezio Auditore da Firenze

Ezio Auditore da Firenze

33.6% of decks · synergy 0.32

Ezio Auditore da Firenze rewards unblocked Assassin damage with escalating effects, and Roshan, Hidden Magister layers on top by converting those same unblocked hits into additional threats, compounding the payoff for successfully pushing damage through.

04
Kadena, Slinking Sorcerer

Kadena, Slinking Sorcerer

31.8% of decks · synergy 0.31

Kadena, Slinking Sorcerer is a morph commander, and Roshan, Hidden Magister's face-down deployment means every Assassin he puts onto the battlefield arrives as a free morph — letting Kadena's draw trigger fire the moment you flip one.

05
Missy

Missy

24.4% of decks · synergy 0.24

Missy cares about creature types from across different properties, and Roshan, Hidden Magister slots in as an Assassin-tribal payoff that generates card advantage independently of Missy's own text, giving the deck a redundant engine when the commander gets answered.

Format Analysis

Where it lives, where it can’t

FormatVerdict
commander legal
legacy legal
modern legal
pioneer not legal
standard not legal
vintage legal
pauper not legal
oathbreaker legal

Commander is where Roshan, Hidden Magister actually functions — the format's longer games and tribal-synergy environment give Assassin-based strategies the time and density they need to make his trigger fire repeatedly. In Legacy and Vintage he's legal but irrelevant; a five-mana creature that requires a specific creature type to do anything useful has no competitive window in formats that end on turn two or three. Oathbreaker is the one non-Commander 60-card format worth mentioning: if you're running an Assassin-centric signature spell package, Roshan can serve as the planeswalker-support piece, though the format's smaller deck size makes the tribal density easier to hit.

Price Context

Current price

$0.27 bulk tier

At $0.27, Roshan, Hidden Magister is deep bulk — pick it up for essentially nothing if you're building Etrata or Altaïr. Bulk rares with narrow tribal applications rarely climb unless the tribe gets a high-profile push, so don't expect the price to move.
