Treachery card art
Treachery steals a creature and immediately untaps five lands, effectively making a five-mana Control Magic cost nothing after the trigger resolves. It is the strongest creature-theft spell in Commander, and decks like Orvar, the All-Form and Merieke Ri Berit treat it as a must-include.

Merieke Ri Berit already wants to steal creatures repeatedly, and Treachery pairs with that plan by refunding the mana spent — letting you hold up interaction or chain into another theft effect the same turn.

Commander is where Treachery does its best work: five mana is easy to hit by the midgame, and the untap trigger routinely generates a full turn of mana advantage on top of a stolen threat. In Legacy and Vintage it is legal but rarely played — faster formats punish five-mana sorcery-speed spells without a free-spell exception, and Treachery's untap trigger doesn't compensate for the tempo loss the same way it does across a longer Commander game. Oathbreaker follows Commander rules closely enough that the same logic applies, and in any format where it's legal it belongs in blue decks that can curve into it.

Budget Alternatives

Cheaper options that do most of the same work

Callous Oppressor and Confiscate are both well under a dollar and trade away the mana-untap trigger entirely, which is most of what makes Treachery exceptional — you're paying for the effect, not just the theft. Mass Manipulation and Blatant Thievery steal multiple permanents at higher mana costs and are worth considering if your deck wants a late-game closer rather than a tempo play, but neither recoups its cost the way Treachery does.

Price Context

Current price

$42.27 premium tier

At $42.27, Treachery sits firmly in the premium tier — it has never been reprinted, which is the entire reason the price is this high. Demand from Commander is consistent enough that this number is unlikely to soften without a reprint announcement.
