The Commander

Menace

Creatures you control have wither. (They deal damage to creatures in the form of -1/-1 counters.)

Whenever a creature an opponent controls dies, if its toughness was less than 1, draw a card.

Guide

Gameplan

You attack with a wide or evasive board to ping opponents' creatures with wither, shrinking them to lethal toughness so they die and you draw cards. Many builds combo off by giving Massacre Girl deathtouch plus an untapper or a free-attack/fight engine to chain through entire boards, drawing your library and finding a finisher.

Strengths

Massive card advantage engine that refills your hand by killing opposing creatures
Powerful board-wipe combos with deathtouch + repeated combat/fight effects
Menace makes her hard to block and pressures the table
Mono-black gives access to elite tutors and ramp

Weaknesses

Heavily commander-dependent and vulnerable to removal
Needs deathtouch enablers to truly pop off, otherwise grindy
Wither only matters in combat or fights, so creature-light/control opponents blunt her
Single color limits interaction (no counters, weak enchantment removal)

Key Cards

Glistening Oil — Grants deathtouch so any wither damage kills, instantly turning Massacre Girl into a one-sided board wipe.
Fireshrieker — Double strike plus deathtouch lets her assign lethal -1/-1 counters and trample-through to chain kills.
Nemesis Mask — Forces all creatures to block her, so with deathtouch she wipes the board and draws a card per creature.
Maze of Ith — Untaps her after combat or removes blockers, enabling repeated wither swings.
Grave Pact — Each opponent creature death from your wither forces additional sacrifices, snowballing the board control.
Cauldron of Souls — Recurs your wither creatures and shrinks them to refill via her draw trigger.

Upgrade Path

Add fast mana (Dark Ritual, Sol Ring) and elite tutors (Demonic Tutor, Vampiric Tutor) to reliably assemble deathtouch + untap loops. Stack redundant deathtouch granters (Quietus Spike, Loxodon Warhammer-style equipment) and protection like Lightning Greaves or Swiftfoot Boots. Top it off with a deterministic payoff such as Torment of Hailfire or Exsanguinate to convert your card flood into a kill.

Archetypes

Combo — Deathtouch plus untap/extra-combat or fight loops lets her kill the table's board and draw your deck.
Aristocrats — Wither deaths feed sacrifice payoffs and Grave Pact-style attrition.
Voltron Control — Menace plus deathtouch turns her into an evasive board-keeper that grinds opponents out.
Wither Tribal — Her ability gives every creature wither, supporting a swarm that erodes opposing boards.
