Warhammer 40,000 — In the Grim Darkness

Commanded by Marneus Calgar, Chapter Master, this Mardu (white/black/red) 100-Card Commander Deck is about an empire that pays for everything in people. The Imperium holds a million worlds with no strategy but volume; the Chaos gods make a competing offer, one man and one gift at a time. Both sides spend bodies — the Imperium the bodies it has, Chaos the body it is — and this deck plays them against each other on the same board.

• Tithe: sacrifice a creature you control: add {1}, and spend it only to cast a spell with Tithe. It works from your hand, so the soldiers pay for the order they die for. Tithe mana buys nothing else — no rock, no removal, no ability — so the deck manufactures bodies in series: Calgar makes two Imperial Guardsmen every combat, and Belisarius Cawl turns each sacrifice into a Servitor. A tax with a spending code on it.
• Chaos Boon: pay the cost for an effect well above its rate — Abaddon destroys a creature, Magnus draws three, Ahriman tutors — and put a mutation counter on the creature. At four it is sacrificed and the opponent to your left gets a 3/3 Chaos Spawn. The corruption is personal, and the power you used reappears in front of a neighbour, pointed at you. Seating matters.
• Two combos: The Forge Never Stops — Techmarine of the Forge and Chaplain Cassius loop Servitors into infinite Tithe mana and a table drain. Everybody Gets One — Fabius Bile, Belisarius Cawl and The Storm of Discord mutate every opposing creature to death.

Why Mardu

White is the Imperium as an institution: the Codex Astartes, the oath, the commissar who shoots one man to steady ten and files the paperwork that evening. Black is the count — the levy that is never short, and Chaos, whose reward arrives as a deformity. Red is the war that was never meant to end. Thirty-three cards carry the Tithe line word for word, twelve Chaos creatures carry the Boon, and twenty-two cards touch mutation counters. Calgar himself never mutates: he makes the bodies and signs.
