Is Agent of Treachery good in Commander?

Agent of Treachery in Commander — Combos, Decks & Price

Agent of Treachery steals any permanent on entry — no targeting restriction, no exceptions — and if you control three or more permanents you stole, you draw three cards at your end step. Seven mana is steep, but commanders like Y'shtola Rhul that flicker or recur it repeatedly make the cost irrelevant after the first cast.

Commanders with the highest synergy

01

Y'shtola Rhul

73.0% of decks · synergy 0.69

Y'shtola Rhul's ability to return Agent of Treachery from the graveyard to the battlefield means every removal spell your opponents fire at it just resets the engine — you retrigger the steal, stack stolen permanents, and draw three cards each turn cycle without paying seven mana again.

02

Xanathar, Guild Kingpin

37.7% of decks · synergy 0.35

Xanathar, Guild Kingpin lets you play off the top of opponents' libraries, and Agent of Treachery converts their best permanents into yours before you even spend your own resources — the two effects compound into a lock that dismantles tables quickly.

03

Yorion, Sky Nomad

36.6% of decks · synergy 0.33

Yorion, Sky Nomad flickers Agent of Treachery on every attack, resetting the "steal a permanent" trigger to hit a fresh target each time while the original stolen permanent stays under your control permanently.

04

Brago, King Eternal

34.1% of decks · synergy 0.31

Brago, King Eternal does exactly what Yorion does but in combat on every swing — Agent of Treachery is one of the highest-value flicker targets in the deck because each blink nets a new permanent and refreshes the draw-three condition.

05

Roon of the Hidden Realm

32.7% of decks · synergy 0.31

Roon of the Hidden Realm can blink Agent of Treachery at instant speed on each player's end step, letting you systematically dismantle the table one permanent at a time while building toward the three-stolen-permanents draw trigger.

Where it lives, where it can’t

Format	Verdict

standard	not legal
vintage	legal
pauper	not legal

Commander is the natural home for Agent of Treachery — four opponents means four target-rich environments, and flicker and recursion commanders turn a single seven-mana spell into a repeating engine that takes over the board. In Pioneer and Modern it sees fringe play in value-blink shells, but seven mana is genuinely hard to reach in those formats and the payoff rarely justifies the curve. Legacy and Vintage offer more broken things to do at that mana investment, so Agent of Treachery effectively stays benched there. Stick to Commander, where the card is at its unambiguous best.
