Torment (a.k.a. the black set) is the second set, and first small expansion, in the Odyssey block. It is the 25th Magic expansion and was released on February 8, 2002.
Torment featured 143 black-bordered cards (55 commons, 44 uncommons and 44 rares). Its expansion symbol represents a nightmare, to evoke the set's dark themes and 'dementia summoning'. Torment was notable for its shift from the conventional distribution, and equal focus, on all the five colors of Magic to a particular thematic and mechanical emphasis on black. Consequently, from the set's development on, it was referred to as the "black set". To account for the over-representation of black, the total number of green and white cards was accordingly reduced; there are 40 black cards, 28 blue and red, 21 green and white, and there are 5 nonbasic lands. The following expansion, Judgment, would later correct the inequality of black, green, and white cards. In addition to there being more black cards, the general level of power of black cards was comparably more powerful than those of other-colored cards.
In addition to a higher-than-usual number of black cards, there are numerous cards in other colors that specifically refer to black or Swamps (e.g., Major Teroh, Stern Judge, Cephalid Snitch, Barbarian Outcast, Enslaved Dwarf, Krosan Constrictor, Nantuko Blightcutter, Cabal Coffers), are thematically related to black (e.g., Possessed Nomad, Possessed Aven, Possessed Barbarian, Possessed Centaur), or use black mana (e.g., Balshan Collaborator, Pardic Collaborator).
Torment was noted for featuring a four-card cycle of tainted lands, which could add black mana or mana of another color if their controllers controlled a Swamp and were the only lands in the expansion. The original basic land artists of Odyssey were commissioned to do darker versions of their original basic lands.
