Torment of Hailfire turns a large black mana supply into pressure on every opponent at once. Each repetition asks opponents to discard a card, sacrifice a nonland permanent, or lose three life. A small Torment can strip resources, but the card becomes most threatening when X is high enough that opponents run out of expendable cards and permanents before the process ends.
Cabal Coffers with Urborg, Tomb of Yawgmoth is a natural foundation for a large cast. Crypt Ghast and Nirkana Revenant give Swamp-heavy decks additional ways to build the required mana. These engines suit mono-black control and slower black midrange decks that spend the early turns trading resources before converting an established mana advantage into a finishing spell.
Timing changes the result dramatically. Casting Torment after a board wipe leaves fewer permanents available to sacrifice, while discard effects reduce the number of cards that can absorb repetitions. Conversely, an opponent with many tokens can sacrifice those tokens instead of losing life. Count what each player can afford to give up before deciding whether your available mana is enough.
Torment does not target opponents, and its life loss is not damage. It also does not guarantee identical outcomes around the table: each opponent makes their own choices during each repetition. Treat it as a resource-based finisher, and keep interaction available when possible so a single counterspell does not waste the turn spent assembling your mana.
