Massacre wipes all creatures with toughness 1 or less for free if an opponent controls a Plains and you control no Plains — a conditional but devastating board reset that costs zero mana. Outside of Massacre Girl, Known Killer shells, you're running it because your meta has white decks and you want a no-mana-investment answer to token floods and deathtouchers.
Best Commanders
Commanders with the highest synergy

Massacre Girl, Known Killer
Massacre Girl, Known Killer's triggered ability deals 1 damage to all other creatures whenever something dies, which turns any Massacre into a chain-reaction wipe far beyond toughness 1 — the name match is incidental, the engine is real.

Maha, Its Feathers Night
Maha, Its Feathers Night reduces the toughness of all non-black creatures, which pushes a wider range of threats into Massacre's kill range and makes the free cost even more punishing for white-heavy opponents.

Massacre Girl
Massacre Girl's -1/-1 on entry pairs directly with Massacre's toughness-1 threshold, and running Massacre as a zero-mana setup piece means you can deploy the commander and immediately clear the board of anything that survived the initial wither trigger.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | not legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Commander is where Massacre earns its slot — free spells are structurally powerful in a format where mana is your most constrained resource, and Plains are common enough that the condition fires reliably. In Legacy and Vintage, the free clause is attractive but the toughness-1 floor is too narrow when Swords to Plowshares and Fatal Push exist at the same or lower cost. Oathbreaker follows Commander's logic: if your meta has white players, Massacre is live.

Price Context
Current price
$4.89 cheap tier
At $4.89, Massacre sits at the bottom of the mid-budget range — cheap enough that it's not a barrier for Commander players who know they want it. It's a niche card with a loyal audience in black-based Commander builds, so the price is stable rather than a deal to chase or avoid.
