MassacreHow it works & interactions with other cards

What It Does

Massacre is a sorcery that gives all creatures -2/-2 until the end of the turn. While its standard cost is four mana, it features a special static ability that allows you to cast it for free if an opponent controls a Plains and you control a Swamp. This check happens as you are casting the spell, looking only for the specific land subtypes, not necessarily basic lands.

How It Resolves

When Massacre resolves, every creature currently on the battlefield is affected by the -2/-2 penalty. This includes your own creatures. Creatures that have their toughness reduced to 0 or less are put into their owners' graveyards as a state-based action. Note that the effect only applies to creatures on the battlefield at the moment the spell resolves; any creatures entering the battlefield later in the turn will not be affected.

Common Mistakes

A common error is forgetting that Massacre affects your own board, unlike some modern one-sided wipes. Additionally, players often assume the 'free' condition requires basic lands. In reality, any land with the 'Plains' or 'Swamp' subtype—such as Shock lands or Triomes—will satisfy the requirement. Lastly, remember that Massacre does not target; it will affect creatures with Hexproof or Shroud.

When to Play It

Massacre is best used as a tempo swing against aggressive decks playing white. By casting it for free, you can clear a board of tokens or small utility creatures and still have all your mana available to develop your own board or hold up interaction. It is also excellent for bypassing protection from black, as it does not target.

Interaction examples

Stacking the Debuff

Massacre Girl

If you cast Massacre followed by Massacre Girl, the initial -2/-2 from the sorcery will likely cause several small creatures to die. When Massacre Girl enters, her trigger gives another -1/-1. Because creatures died earlier, Massacre Girl's second ability will trigger multiple times, potentially clearing even high-toughness creatures by stacking repeated -1/-1 effects.

Health and Resource Management

Toxic Deluge

If you are facing a board of 2/2 creatures and an opponent has a Plains, Massacre is superior to Toxic Deluge because it costs zero mana and zero life. However, if the opponent has a 3/3 creature, Massacre will not kill it alone, whereas Toxic Deluge could be scaled up by paying 3 life and three mana to ensure the threat is removed.

Synergy with Death Triggers

The Meathook Massacre

If you have The Meathook Massacre already on the battlefield and cast Massacre, any creature that dies from the -2/-2 penalty will trigger the enchantment. You will gain 1 life for every opponent's creature that dies and each opponent will lose 1 life for every creature you lose, significantly swinging the life totals while clearing the board.

Recovering After the Wipe

Victimize

After casting Massacre for free to clear the opponent's small creatures, you might have a creature of your own that survived with reduced toughness. You can then cast Victimize, sacrificing that weakened creature to bring back two larger creature cards from your graveyard that were not affected by the Massacre.
