Peacekeeper shuts off all creature attacks for as long as you keep paying one white mana during your upkeep — a hard stax ceiling on combat that costs three mana to land. It's one of the cleanest pillowfort pieces in white, and at its price point there's almost no reason to play around it.

Peacekeeper is almost exclusively a Commander card — the format's multiplayer dynamics make a persistent attack-lock dramatically more punishing than in any one-on-one format, and the slower pace means three mana plus an upkeep cost is entirely manageable. In Legacy and Vintage it's technically legal but sees no competitive play; creature-based combo and tempo strategies don't want a slow, upkeep-dependent lock piece when interaction is faster and cheaper. Commander is where Peacekeeper earns its slot: stax and pillowfort shells that want to survive long enough to assemble a win condition treat it as a reliable, repeatable deterrent against the entire table.

Budget Alternatives
Cheaper options that do most of the same work
Kithkin Rabble and Sphere of Safety don't replicate the effect, but Norn's Annex comes closest to Peacekeeper's function — it taxes every attack with life or Phyrexian mana, requires no upkeep payment, and costs under a dollar. Windborn Muse is another strong comparison at a similar price floor, trading Peacekeeper's hard lock for a softer two-generic tax per attacking creature, which is easier to play around but also harder for opponents to simply remove and ignore.
Price Context
Current price
$9.69 mid tier
At $9.69, Peacekeeper sits in the mid tier — affordable enough to include without budgetary hand-wringing, expensive enough that you want to be sure the slot is earning its keep. The price reflects a genuine scarcity from a single old printing rather than any secondary-market hype, so it's unlikely to drop significantly without a reprint.
